Camera Pixels App (Updated Review): Significant improvements in the new version make this a best-in-class app

I’ve posted repeatedly about the importance of understanding how to take manual control of your camera in order to make images that are properly exposed and focused.  Whether you are using a professional DSLR, an advanced full-frame mirrorless ILC, a compact point-and-shoot, or the camera built into your smart phone, there is no way you will get consistently acceptable results if you leave the camera’s settings to its auto mode.  See this post for an overview: Post on Beyond the Auto Mode.

About three months ago, I posted a review of an early version of an iPhone app called “Camera Pixels”.  In that review, I found the app to be a very promising concept due to its advanced DSLR-like features and intuitive controls, but I couldn’t fully endorse it in the earlier version because I found several bugs and interface quirks.  You can read that earlier review here: Previous review of early version of Camera Pixels app.  Since that review was published, I have had several discussions with the Camera Pixels support team to detail my concerns about the various issues I found.

For the past two days I have been testing a new version of the Camera Pixels app, and I can now recommend it wholeheartedly.  The new release preserves the advanced features and (relatively) simple interface of the earlier version, but it has addressed all of the significant issues I outlined in my review of the previous release.  Specifically:

  • the image flicker in the “viewfinder” area of the screen has been eliminated,
  • the bracketing of exposures now retains the proper requested spacing (unless at a physical limit of a setting),
  • there is a new “Pro View” mode that keeps the manual settings toolbar always on the screen so any manual overrides are immediately apparent, and
  • the controls to separate the exposure point from the focus point are now more intuitive.

Like the “Manual” camera app that I’ve been using for years and the “ProCam 4” app that has been my go-to camera control app for the past several months, the new “Camera Pixels” app allows the manual selection of ISO, shutter speed, exposure compensation, and focus distance (note that the iPhone camera’s lens has a fixed aperture, so F-stop cannot be manually set).  Also like the Manual app and the ProCam 4 app, Camera Pixels allows images to be captured using RAW mode, which has a great many advantages over capture in JPEG format (see this post for more information: Post on RAW Capture).  And all three of these camera apps display a histogram to assist in setting exposure properly.  

In addition, both Camera Pixels and ProCam 4 (but not Manual) offer some very useful advanced camera control capabilities, including the following:

  • Shutter Priority: You can choose an exposure mode in which you select the shutter speed first and the app will set the appropriate ISO.
  • Exposure Bracketing: You can shoot a series of four shots at different exposures to increase the likelihood that one of them will be at the best exposure for the lighting conditions.  The series of shots can also be combined using HDR tools found in Lightroom, Photoshop, and other editing software into a single image with a higher range of tones from very dark to very bright.
  • White Balance: You can adjust white balance in the app, which is often preferable to having to adjust it in your RAW files during post-processing.
  • Virtual Horizon: The display can show you when the horizon is level.
  • Slow Shutter Options: You can select long fixed shutter speeds as well as bulb mode to keep the shutter open for as long as you’d like.
  • RAW+JPEG: You can choose to store the image in both RAW and JPEG formats.

With all this incremental functionality, your little phone’s camera begins to behave a lot like a more advanced standalone camera.  While the iPhone’s camera, with its small sensor and its tiny fixed-aperture non-interchangeable lens, still cannot compare to a professional or enthusiast DSLR or ILC camera, the results using an advanced manual camera control app such as Camera Pixels or ProCam 4 are vastly improved compared to using the phone’s native camera app.  At iTunes App Store pricing of $2.99 for Camera Pixels or $4.99 (temporarily reduced to $1.99) for ProCam 4, either of these apps is a great buy and a serious enhancement to the iPhone’s built-in camera.

There are some significant differences between Camera Pixels and ProCam 4.  ProCam 4 offers advanced image editing capabilities, while Camera Pixels does not.  However, Camera Pixels offers more flexible exposure bracketing options, the ability to separate exposure point from focus point, a better histogram, and more advanced RAW and video shooting options.  And a significant advantage of the new Camera Pixels app over ProCam 4 is its simple and intuitive user interface for setting and resetting the manual camera control features such as exposure compensation, shutter priority, and ISO priority.  In fact, the Camera Pixels app comes the closest I’ve ever found to the user interface of an advanced DSLR or mirrorless camera.

One note to enhance the usability of the Camera Pixels app: As far as I can tell, there is no built-in help content in the app itself, but there is a very useful online user guide available from the app’s developers.  You can find the user guide here: Camera Pixels app user guide.

In summary, the new Camera Pixels app is a great concept that comes closest of any camera control app I’ve found to the look-and-feel of an advanced standalone camera.  With the greatly improved new release, Camera Pixels has become the best option I’ve found for iPhone users wishing to control the phone’s built-in camera like an advanced DSLR or mirrorless standalone camera.  I now fully recommend this app, and I plan to use it as my first choice for advanced control of my iPhone’s camera.

Decent Exposure [Encore Publication]: Mastering exposure is key to getting great images

Of all the primary elements a photographer controls–composition, focus, the moment the shutter is released, and of course the choice of the subject–none is more critical to making a great image than setting a proper exposure.  Some corrections to a poorly exposed image can be made in post-processing, and there are occasionally good artistic reasons to override the norms of exposure in order to evoke a certain mood in an image by making it darker or brighter than usual, but before we can effectively make these exceptional choices it is necessary to learn the basics of setting an appropriate exposure.

Let’s begin by defining exposure and the elements that comprise it.  Simply put, exposure refers to the amount of light that reaches the camera’s sensor and therefore how light or dark the resulting image will appear.  Four components together determine the exposure: 1) the brightness of the light reflecting off the subject and reaching the front of the lens, 2) the aperture setting on the lens (how wide or narrow is the opening of the lens), 3) the shutter speed setting (how long is the camera’s shutter open to allow light to strike the sensor), and 4) the sensitivity setting of the camera’s sensor.  We don’t always have control over the first component, but the other three are within our control using our camera’s settings.

Many photographers simply set their camera on Auto mode and let the camera’s built-in meter make its best guess as to how the image should be exposed.  That method can work well under certain conditions, but it is highly prone to errors.  For example, if your main subject is strongly backlit, the camera’s meter will expose for the average brightness in the scene and will underexpose the subject.  This is why so often we see underexposed photos of people standing outside in bright sunlight.

Although I compensated for the strong backlighting in this image of a Tibetan family enjoying a midday picnic, their faces are still quite shadowy, indicating a bit brighter exposure would have been better still.  Buy this photo

Fortunately, there are several easy methods to achieve a correct exposure even under challenging lighting conditions.  Here are a few that I use frequently:

  1. Set the camera’s metering mode to Spot Metering: By default most cameras’ metering systems use a sophisticated pattern-matching algorithm that measures how bright or dark each area of the image is and makes its best guess about a workable exposure based on similar scenes in the camera’s database.  Most cameras allow you to select a simpler metering mode called Spot Metering, that just measures the light at the central point in the image or another point that you select.  If you choose Spot Metering and select the measuring point to be right where your main subject is, you should get just the right exposure.
  2. Dial in some exposure compensation: Most cameras let you override the meter’s exposure setting by dialing in a compensation setting to lighten or darken the image.  If your subject is backlit, you will likely want to increase the exposure by one to two stops (each “stop” of additional exposure represents a doubling of the amount of light reaching the sensor).  The camera’s display should show something like “+1 EV” to alert you that you’ve dialed in 1 extra stop of exposure, and the number changes as you change the compensation setting.  Just be sure to set the exposure compensation back to zero when you’re done using it.
  3. Go fully manual: To gain complete control over your camera’s exposure settings, choose the meter’s Manual mode.  Then you can change all three exposure elements (shutter speed, aperture, and ISO) until the image appears properly exposed when you review it on your camera’s display.
  4. Use flash to increase the lighting on your main subject: One good way to achieve proper exposure with a backlit subject is to increase lighting on the subject itself, so that there is no longer such a difference in brightness between the subject and the background.  Your camera’s built-in flash may be strong enough to pull off this trick, but it often helps to have a more powerful flash unit with you.  There are some other reasons why you may not want to use flash as a main source of light on your subject, so this method should be used sparingly.  A reflector can be used instead of flash to reflect some of the sun’s light onto the front of your subject.

For this photo shoot with a musician friend, I shot into the light so she wouldn’t have to squint into the sun and also so that we’d have a beautiful rim light from the sun around her hair.  To pull this off, I used manual mode and selected the proper exposure for her face.  I employed a reflector to bounce some sunlight back onto her face and trumpet.  [Client image not for sale.]

Similar methods can be used for other challenging lighting conditions besides backlighting.  If the subject is a brighter or darker color than the “neutral gray” your camera’s meter uses for a standard, then you need to dial in more or less exposure as appropriate.  My black cat Dragonfly, for example, requires an especially dark exposure to override the meter from thinking he’s a gray cat and choosing too bright an exposure.  Similarly, a white polar bear will need additional exposure to stop the meter from underexposing what it assumes to be a gray bear.

When photographing a black subject, reduce the exposure to compensate for the light meter’s mistaken assumption that the subject is a neutral gray color.  Buy this photo

Whatever method you use to choose your exposure, be sure to take a look at the resulting image using your camera’s monitor.  Does the main subject appear to be properly exposed, or is it still too dark or perhaps too bright?  If your camera offers a histogram display, learn how it works and use it to check your exposure in tricky lighting conditions.  I’ll write a future post specifically about the histogram, as it is a very useful and often overlooked feature.

With some attention to the exposure of your images and use of some of the techniques described here, you can achieve a correctly exposed image nearly all of the time.  After mastering the essentials of exposure, you will have more keepers and fewer images in the virtual trash can, and you can even begin to break the rules for artistic effect.

Bracketing: Hedging Your Bets [Encore Publication]: In challenging shooting conditions, exposure bracketing is a great insurance policy

In the old film days of photography, it would be days or even weeks after shooting before we could see the results.  I would routinely use a procedure called “bracketing” to make a series of shots, each at a slightly different exposure, to increase the odds that one would come out decently exposed.  Even today, when digital photography allows us to see the results immediately, there are two good reasons to employ the exposure bracketing technique: 1) it can be hard to assess on a small LCD screen in bright daylight and while in the excitement of shooting whether the exposure is really correct, and 2) when the contrast between the brighter and dimmer parts of the scene is high we may want to stitch several different exposures together using software to create a high dynamic range (HDR) image later.

Tricky subjects, like this tiny Svalbard reindeer against a glacier background, benefit greatly from exposure bracketing.  From a series of 5, 7, or even 9 images shot at slightly different exposures, you can choose the one with the correct exposure for the conditions.  Buy this photo

So there are still good reasons to use exposure bracketing, and fortunately, it is quite easy to employ this technique.  Here’s how.

If possible, mount your camera on a tripod when using bracketing so it won’t move between exposures.  Then you can combine several of the exposures into an HDR image later if desired.

If your camera has a bracketing button or menu item, use it to specify how many shots you want to take (I usually shoot 5 or 7 different exposures when bracketing) and how much you want to vary the exposure between each shot and the next (often I choose a 1-stop difference).  If your camera lacks this feature, you can still use bracketing by manually adjusting the exposure between each shot and the next; just use your camera’s exposure compensation control to dial in first -2 stops, then -1 stop, then 0, then +1 stop, and finally +2 stops.

I like to set my camera for continuous shooting while bracketing.  That way, I just hold down the remote shutter release and the camera shoots all 5 or 7 exposures in rapid succession.  But it’s fine to shoot each frame individually in single release mode, if you prefer.

There are some subtleties to think about when employing exposure bracketing.  Some cameras let you choose whether to vary the aperture, the shutter speed, or the ISO setting, while holding the other two settings constant.  In most cases, I prefer to vary the shutter speed and hold the aperture and ISO settings constant, because changing the aperture affects the images’s depth-of-field, and changing the ISO setting can affect the noise in the image.

Later, during post-processing, you review the images and choose the one that is properly exposed.  Or if the scene is very high contrast, you can use photo editing software such as Lightroom or Photoshop to stitch several frames in your series together into an HDR image, which ensures good exposure from the brightest to the darkest tones in your photo.

Several exposures were shot using bracketing and then combined in Photoshop to create this HDR  image.  All tones from the darkest shadows on the mountain walls to the brightest highlights on the icebergs and lake are properly exposed in the final image.  Buy this photo

Have you used exposure bracketing techniques?  What are your best practices?  Do you use this process mostly for selecting the best exposure or for creating HDR images?  Please share your thoughts here.

Top Tips for Great Travel Images [Encore Publication]: These five simple “hacks” will result in more professional images

Festivals and street fairs can be challenging to shoot due to backgrounds cluttered with people, buildings, and cars.  To make this portrait of grandmother and granddaughter at Carnaval San Francisco, I got down low so that most of the background was covered by the cloth of the costume, and I used a wide aperture to throw the hectic street scene into soft focus.  Buy this photo

The web is positively overflowing with “life hacks,” simple tips and tricks to save us all time and effort and to achieve better results.  Some lists are better than others, but it is in the spirit of these lists that I bring you this compilation of five simple travel photography hacks.  These techniques are not difficult and do not require expensive gear.  They work equally well for your photography whether traveling or at home.  And I promise that if you follow them, your images will improve.  The pros do these things almost automatically; to them, it’s hygiene, like tooth brushing.  If you read no other post about photography, read this one.

  1. Avoid cluttered backgrounds: So often the travel images of a professional stand out from those of amateurs simply because they took careful notice of what was in the background while composing the shot.  Try to frame your subject against a clean backdrop such as a dark-colored wall or the sky.  If there’s no way to avoid including some clutter in the background, at least use a wide aperture (low F-stop number) to throw the background into soft focus.
  2. Watch your horizon: Frequently, we’re so intent on composing the main subject within our viewfinder that we forget to check whether the camera is level before firing the shutter.  An uneven horizon can give the impression of vertigo, like the subject is going to fall out of the frame.  Some cameras have a virtual horizon function to show you whether the horizontal and vertical axes are level, but whether you use it or not, be sure to check visually that the edge of the image looks correct.
  3. Achieve sharp focus: The one characteristic of an image that even the most inexperienced viewer can identify immediately, and one that’s almost impossible to fix in post-processing, is poor focus.  Today’s cameras are so easy to use that we often overlook this most basic element.  The camera can’t know for sure what subject you intend to have in focus; it can only make its best guess.  So take the extra fraction of a second while composing your image to move the camera’s focus point onto the main subject.  Or use a small aperture (high F-stop number) to provide a wide depth of field so that essentially everything is in focus.
  4. Choose the correct exposure: Another very basic element of any photograph, exposure can only be correctly chosen by the photographer, not by the camera.  Your camera’s Auto mode can be fooled very easily by many tricky situations, most commonly by backlighting of the subject.  It’s fine to use the camera’s guess as a starting point, but nearly every camera (including smartphone cameras) have a way to manually override this guess, so learn how to do this and add in about a stop or so of extra exposure if your subject is backlit, more if the backlighting is severe.
  5. Turn off the darned flash: Nearly every camera has a mode where it fires the flash automatically if it determines the extra light is needed.  This is rarely a good thing.  Far better to turn off the auto flash setting and make your own decision about when to use the flash.  Otherwise, your low-light images could end up with an eerie, unnatural color cast or your far-away subject could be underexposed (a flash typically lights an object only a few feet away from the camera, so why fire the flash when you’re photographing an object hundreds of yards or even miles away?).  Worse, if you are shooting through glass or another reflective surface, your flash reflects off the surface, ruining your whole image.  Worse still, your flash may blind everyone else near you in a very dim setting, damage sensitive artwork, or scare or anger nearby wildlife.  I’ve seen countless visitors ejected from museums, zoos and aquariums, and other wonderful destinations because they hadn’t figured out how to override their camera’s auto flash setting.  Just turn off the darned flash, and use it manually when appropriate.

Learn these simple techniques and follow them whenever you shoot, and you’ll start making images that stand out from the crowd.  Remember, you, and not the technology inside your camera, are the creative force behind your images.

While this image of a yurt in the remote mountainous region between China and Tajikistan succeeds in spite of (or perhaps because of) the off-kilter horizon, it serves as a good reminder to check the horizons at the edge of our photos.  Buy this photo

Beyond the Auto Mode [Encore Publication]: Take control of your images by learning to manually set exposure, focus, and more

Travel photography is so exciting and satisfying in part because it requires us to capture every kind of image in all kinds of shooting environments.  You could be heading out to shoot landscapes when suddenly a rare sighting of an animal transforms your activity into a wildlife shoot.  Or you may be on the road for your next destination when you stumble upon a colorful local festival, and now you’re shooting portraits of the revelers.  This rich diversity of subjects also creates one of the biggest challenges for travel photographers: how to be prepared for anything that comes our way.  For beginning photographers there is some comfort in using the Auto mode that nearly every camera offers.  After all, we’re more likely to get an acceptable shot this way, when the subject turns quickly from fast action to landscapes to the low light of evening, or to an indoor performance.  But in most cases, your camera’s Auto mode, which attempts to make its best guesses as to what settings to use given existing conditions, will yield only acceptable photos and not the striking and memorable images we’re after.

There is a better way.  Take control of your images by learning how to manually set your exposure, focus, and other aspects of your photo.  All advanced point-and-shoot cameras and all mirrorless and DSLR cameras allow you to set most functions manually.  Even some basic point-and-shoot models have a way to go manual, but often this will involve options buried deep in a menu somewhere.  And there are apps available for both iOS and Android smart phones that allow you to take manual control over your phone’s camera.  I use an iPhone 6S, and I’ve found the “ProCam 4” app to work very nicely for providing control over the phone’s camera setting for exposure, focus, and flash.  You can find it for less than $5 on the Apple App Store: ProCam 4 App.  Even without using an app, most smart phone cameras do allow you to override the automatic settings by clicking on the part of the image you want to be in focus and used for the exposure setting; usually you can also set the exposure based on a different area of the image from the area that you want to be in focus.  But the dedicated apps will give you greater control, as they allow you to choose the shutter speed, aperture (when not fixed), and ISO for each shot.

For this image of a whirling dervish in Goreme, Turkey, I wanted to blur the dancer so as to give a sense of the continual turning motion in the ceremony, so I used my camera’s shutter-priority exposure mode and selected a slower shutter speed.  Buy this photo

The key to successfully using your camera’s manual settings is to learn how they work and to practice at home, long before you actually take a trip.  Like anything else, selecting the settings we want on a camera takes practice.  In this digital era, it’s easier to learn because you can see the results of each setting immediately on your camera’s screen.  So dig out that camera user guide, or find it online, or search for a good tutorial.  But do learn how to adjust the key settings manually.

The first manual setting every photographer should learn is how to turn off your camera’s flash.  This sounds very basic, but I’m always amazed to see so many flashes going off in inappropriate places: museums that don’t allow flash photography, cultural performances, sports stadiums where the subject is thousands of feet away from the camera (the flash will only provide acceptable lighting for a few dozen feet, at most), and even the shy octopus exhibit at our local aquarium.  Believe me, you do not want to flash the octopus.  So learn how to turn your flash off, and be sure you actually do turn it off when you’re in a venue where flash is inappropriate or won’t help your image be better exposed.  Remember that glass reflects light, so you don’t want your flash on when shooting through windows of a vehicle or the glass windows of animal enclosures at zoos or aquariums.

Next, learn how to set your camera’s exposure manually.  The light meters built into today’s cameras are very smart, but they are also easily fooled by tricky lighting conditions.  The most common problem is backlighting.  If your subject is lit from behind, as many outdoor subjects are, your camera’s auto mode will likely expose for the brighter background and will leave your main subject underexposed.  You can adjust for this is several ways.  It may be good enough to just use your camera’s exposure compensation button to dial in, say, one extra stop of exposure.  Use your camera’s LCD screen and (if it has one) the histogram, to see how the subject is exposed with varying levels of compensation.  In some cases (if your main subject is quite close to the camera), you can use fill flash to fix backlighting problems.  To do so, manually turn on your camera’s flash, or attach a separate flash unit, and choose the setting for “fill flash” or “balanced TTL” (through the lens) flash mode.  Again, check exposure using your camera’s screen and histogram.  I find I usually get good results in tricky lighting conditions by using my camera’s spot metering mode, which tells the camera’s meter to use only the very center (or whatever area I select) of the image when choosing the exposure.

Other than allowing you to properly expose your main subject, manually setting the exposure also gives you control over what combination of shutter speed (how long the exposure lasts), aperture (how wide the lens is open), and ISO (how sensitive the camera is to light) you want for each shot.  If you’re shooting fast moving action like sports or wildlife, you will likely want to choose a fast shutter speed to freeze the motion (unless you want a blur effect as an artistic choice).  If you’re photographing a waterfall or sky and want to get some nice blurring of the water and/or clouds, you will probably want to choose a slower shutter speed.  Many times you want only certain parts of the image to be in focus.  A wide aperture (low F-stop number such as f/1.8) will give you a shallow depth-of-field, allowing only one part of the image to be in focus and blurring the other parts.  Conversely, a narrow aperture (high F-stop number such as f/16) will allow all parts of the photo to be in focus.  The final element determining exposure is the sensitivity of the camera’s sensor, measured by an ISO number.  Select a higher ISO (such as 1600 or above) only when you really need the extra sensitivity for very low-light subjects when a longer shutter speed or wider aperture is not suitable.  When you use very high ISO settings, the image will tend to have a lot of noise.  Today’s cameras are getting better at limiting noise at high ISO settings, and there are ways to reduce some of the effects of the noise using post-processing software, so my approach is to use as high an ISO as is required after considering the range of available shutter speeds and apertures.

To capture these professional beach volleyball players in sharp focus and to freeze the moment, I selected single-focus-point focus mode and chose the exact spot in the viewfinder where the players would be positioned, and also used my camera’s shutter-priority exposure mode to select a very fast shutter speed.  Buy this photo

The other major type of manual setting that you need to know how to use is focus.  Most cameras today do a pretty good job of choosing the right part of the image to focus on, but they often need some help from the photographer.  From simple smart phone cameras through professional DSLRs, the autofocus function almost always lets the photographer select what part of the image they want to be in focus.  If you keep your camera in fully autofocus mode and don’t help by selecting where your main subject is, it may very well guess incorrectly and put another part of the image as the center of focus.  So, learn how to select the focus point even while letting your camera’s autofocus mechanism actually choose the focus distance.  Sometimes a camera’s autofocus capability may not work for the conditions under which you’re shooting, and in these cases you need to turn off autofocus completely, and focus in manual mode.  Some instances when this is necessary are when shooting in very low light conditions, or when shooting in poor contrast environments (for example, your subject’s texture looks a lot like that of its background, or you’re shooting into the bright sun).  In these cases, turn off the autofocus function and adjust focus manually until the subject looks sharp.

It’s still fine to walk around during your travels with your camera set in fully Auto mode, just in case something very unexpected comes up.  But do know how to set the main functions manually so you’ll get the best possible images in the 95% of the shooting situations when you do have time to set up first.

Bracketing: Hedging Your Bets [Encore Publication]: In challenging shooting conditions, exposure bracketing is a great insurance policy

In the old film days of photography, it would be days or even weeks after shooting before we could see the results.  I would routinely use a procedure called “bracketing” to make a series of shots, each at a slightly different exposure, to increase the odds that one would come out decently exposed.  Even today, when digital photography allows us to see the results immediately, there are two good reasons to employ the exposure bracketing technique: 1) it can be hard to assess on a small LCD screen in bright daylight and while in the excitement of shooting whether the exposure is really correct, and 2) when the contrast between the brighter and dimmer parts of the scene is high we may want to stitch several different exposures together using software to create a high dynamic range (HDR) image later.

Tricky subjects, like this tiny Svalbard reindeer against a glacier background, benefit greatly from exposure bracketing.  From a series of 5, 7, or even 9 images shot at slightly different exposures, you can choose the one with the correct exposure for the conditions.  Buy this photo

So there are still good reasons to use exposure bracketing, and fortunately, it is quite easy to employ this technique.  Here’s how.

If possible, mount your camera on a tripod when using bracketing so it won’t move between exposures.  Then you can combine several of the exposures into an HDR image later if desired.

If your camera has a bracketing button or menu item, use it to specify how many shots you want to take (I usually shoot 5 or 7 different exposures when bracketing) and how much you want to vary the exposure between each shot and the next (often I choose a 1-stop difference).  If your camera lacks this feature, you can still use bracketing by manually adjusting the exposure between each shot and the next; just use your camera’s exposure compensation control to dial in first -2 stops, then -1 stop, then 0, then +1 stop, and finally +2 stops.

I like to set my camera for continuous shooting while bracketing.  That way, I just hold down the remote shutter release and the camera shoots all 5 or 7 exposures in rapid succession.  But it’s fine to shoot each frame individually in single release mode, if you prefer.

There are some subtleties to think about when employing exposure bracketing.  Some cameras let you choose whether to vary the aperture, the shutter speed, or the ISO setting, while holding the other two settings constant.  In most cases, I prefer to vary the shutter speed and hold the aperture and ISO settings constant, because changing the aperture affects the images’s depth-of-field, and changing the ISO setting can affect the noise in the image.

Later, during post-processing, you review the images and choose the one that is properly exposed.  Or if the scene is very high contrast, you can use photo editing software such as Lightroom or Photoshop to stitch several frames in your series together into an HDR image, which ensures good exposure from the brightest to the darkest tones in your photo.

Several exposures were shot using bracketing and then combined in Photoshop to create this HDR  image.  All tones from the darkest shadows on the mountain walls to the brightest highlights on the icebergs and lake are properly exposed in the final image.  Buy this photo

Have you used exposure bracketing techniques?  What are your best practices?  Do you use this process mostly for selecting the best exposure or for creating HDR images?  Please share your thoughts here.

Camera Pixels App Review: A great concept but still needs work

I’ve posted repeatedly about the importance of understanding how to take manual control of your camera in order to make images that are properly exposed and focused.  Whether you are using a professional DSLR, an advanced full-frame mirrorless ILC, a compact point-and-shoot, or the camera built into your smart phone, there is no way you will get consistently acceptable results if you leave the camera’s settings to its auto mode.  See this post for an overview: Post on Beyond the Auto Mode.

For the past two days I have been testing an iPhone app called “Camera Pixels”.  Full Disclosure: The developer of Camera Pixels requested I test their new app and offered me a free download for trial, but to preserve my independence I paid for the download myself.

Like the “Manual” camera app that I’ve been using for years and the “ProCam 4” app that has been my go-to camera control app for the past several months, the new “Camera Pixels” app allows the manual selection of ISO, shutter speed, exposure compensation, and focus distance (note that the iPhone camera’s lens has a fixed aperture, so F-stop cannot be manually set).  Also like the Manual app, ProCam 4 allows images to be captured using RAW mode, which has a great many advantages over capture in JPEG format (see this post for more information: Post on RAW Capture).  And all three of these camera apps display a histogram to assist in setting exposure properly.  

In addition, both Camera Pixels and ProCam 4 (but not Manual) offer some very useful advanced camera control capabilities, including the following:

  • Shutter Priority: You can choose an exposure mode in which you select the shutter speed first and the app will set the appropriate ISO.
  • Exposure Bracketing: You can shoot a series of four shots at different exposures to increase the likelihood that one of them will be at the best exposure for the lighting conditions.  The series of shots can also be combined using HDR tools found in Lightroom, Photoshop, and other editing software into a single image with a higher range of tones from very dark to very bright.
  • White Balance: You can adjust white balance in the app, which is often preferable to having to adjust it in your RAW files during post-processing.
  • Virtual Horizon: The display can show you when the horizon is level.
  • Slow Shutter Options: You can select long fixed shutter speeds as well as bulb mode to keep the shutter open for as long as you’d like.
  • RAW+JPEG: You can choose to store the image in both RAW and JPEG formats.

With all this incremental functionality, your little phone’s camera begins to behave a lot like a more advanced standalone camera.  While the iPhone’s camera, with its small sensor and its tiny fixed-aperture non-interchangeable lens, still cannot compare to a professional or enthusiast DSLR or ILC camera, the results using an advanced manual camera control app such as Camera Pixels or ProCam 4 are vastly improved compared to using the phone’s native camera app.  At iTunes Store pricing of $3.99 for Camera Pixels or $4.99 for ProCam 4, either of these apps is a great buy and a serious enhancement to the iPhone’s built-in camera.

There are some significant differences between Camera Pixels and ProCam 4.  ProCam 4 offers advanced image editing capabilities, while Camera Pixels does not.  However, Camera Pixels offers more flexible exposure bracketing options, the ability to separate exposure point from focus point, a better histogram, and more advanced RAW and video shooting options.  And a significant advantage of the new Camera Pixels app over ProCam 4 is its user interface for setting and resetting the manual camera control features such as exposure compensation, shutter priority, and ISO priority.  In fact, the Camera Pixels app comes the closest I’ve ever found to the user interface of an advanced DSLR or mirrorless camera.

Unfortunately, in its current state I cannot unreservedly recommend the Camera Pixels app.  I encountered too many glitches during my brief testing to be able to give this app a glowing review at this time.  Here are a few of the issues I noted:

  • The “viewfinder” (image preview on the screen) flickers intermittently, which can be very distracting when trying to compose images.
  • The bracketing exposure settings are sometimes incorrectly spaced, i.e., instead of being exposed at -3, -2, -1, 0, +1, +2, and +3; the sequence may be exposed at -3, -2, -1, 0, +1, +1, and +1.
  • It can be hard to tell if manual overrides are set, leading to incorrect exposures.
  • The very useful feature to separate the exposure point from the focus point doesn’t always work.

In summary, the new Camera Pixels app is a great concept that comes closest of any camera control app I’ve found to the look-and-feel of an advanced standalone camera; however, there are significant bugs in the current version that hamper the shooting experience.  With further development to fix the problems, Camera Pixels could become an excellent option for iPhone users wishing to control the phone’s built-in camera like an advanced DSLR or mirrorless standalone camera.  I will eagerly await the next revision of this app.

Here’s the link to the Camera Pixels app on the Apple App Store: Camera Pixels app.

Decent Exposure [Encore Publication]: Mastering exposure is key to getting great images

Of all the primary elements a photographer controls–composition, focus, the moment the shutter is released, and of course the choice of the subject–none is more critical to making a great image than setting a proper exposure.  Some corrections to a poorly exposed image can be made in post-processing, and there are occasionally good artistic reasons to override the norms of exposure in order to evoke a certain mood in an image by making it darker or brighter than usual, but before we can effectively make these exceptional choices it is necessary to learn the basics of setting an appropriate exposure.

Let’s begin by defining exposure and the elements that comprise it.  Simply put, exposure refers to the amount of light that reaches the camera’s sensor and therefore how light or dark the resulting image will appear.  Four components together determine the exposure: 1) the brightness of the light reflecting off the subject and reaching the front of the lens, 2) the aperture setting on the lens (how wide or narrow is the opening of the lens), 3) the shutter speed setting (how long is the camera’s shutter open to allow light to strike the sensor), and 4) the sensitivity setting of the camera’s sensor.  We don’t always have control over the first component, but the other three are within our control using our camera’s settings.

Many photographers simply set their camera on Auto mode and let the camera’s built-in meter make its best guess as to how the image should be exposed.  That method can work well under certain conditions, but it is highly prone to errors.  For example, if your main subject is strongly backlit, the camera’s meter will expose for the average brightness in the scene and will underexpose the subject.  This is why so often we see underexposed photos of people standing outside in bright sunlight.

Although I compensated for the strong backlighting in this image of a Tibetan family enjoying a midday picnic, their faces are still quite shadowy, indicating a bit brighter exposure would have been better still.  Buy this photo

Fortunately, there are several easy methods to achieve a correct exposure even under challenging lighting conditions.  Here are a few that I use frequently:

  1. Set the camera’s metering mode to Spot Metering: By default most cameras’ metering systems use a sophisticated pattern-matching algorithm that measures how bright or dark each area of the image is and makes its best guess about a workable exposure based on similar scenes in the camera’s database.  Most cameras allow you to select a simpler metering mode called Spot Metering, that just measures the light at the central point in the image or another point that you select.  If you choose Spot Metering and select the measuring point to be right where your main subject is, you should get just the right exposure.
  2. Dial in some exposure compensation: Most cameras let you override the meter’s exposure setting by dialing in a compensation setting to lighten or darken the image.  If your subject is backlit, you will likely want to increase the exposure by one to two stops (each “stop” of additional exposure represents a doubling of the amount of light reaching the sensor).  The camera’s display should show something like “+1 EV” to alert you that you’ve dialed in 1 extra stop of exposure, and the number changes as you change the compensation setting.  Just be sure to set the exposure compensation back to zero when you’re done using it.
  3. Go fully manual: To gain complete control over your camera’s exposure settings, choose the meter’s Manual mode.  Then you can change all three exposure elements (shutter speed, aperture, and ISO) until the image appears properly exposed when you review it on your camera’s display.
  4. Use flash to increase the lighting on your main subject: One good way to achieve proper exposure with a backlit subject is to increase lighting on the subject itself, so that there is no longer such a difference in brightness between the subject and the background.  Your camera’s built-in flash may be strong enough to pull off this trick, but it often helps to have a more powerful flash unit with you.  There are some other reasons why you may not want to use flash as a main source of light on your subject, so this method should be used sparingly.  A reflector can be used instead of flash to reflect some of the sun’s light onto the front of your subject.

For this photo shoot with a musician friend, I shot into the light so she wouldn’t have to squint into the sun and also so that we’d have a beautiful rim light from the sun around her hair.  To pull this off, I used manual mode and selected the proper exposure for her face.  I employed a reflector to bounce some sunlight back onto her face and trumpet.  [Client image not for sale.]

Similar methods can be used for other challenging lighting conditions besides backlighting.  If the subject is a brighter or darker color than the “neutral gray” your camera’s meter uses for a standard, then you need to dial in more or less exposure as appropriate.  My black cat Dragonfly, for example, requires an especially dark exposure to override the meter from thinking he’s a gray cat and choosing too bright an exposure.  Similarly, a white polar bear will need additional exposure to stop the meter from underexposing what it assumes to be a gray bear.

When photographing a black subject, reduce the exposure to compensate for the light meter’s mistaken assumption that the subject is a neutral gray color.  Buy this photo

Whatever method you use to choose your exposure, be sure to take a look at the resulting image using your camera’s monitor.  Does the main subject appear to be properly exposed, or is it still too dark or perhaps too bright?  If your camera offers a histogram display, learn how it works and use it to check your exposure in tricky lighting conditions.  I’ll write a future post specifically about the histogram, as it is a very useful and often overlooked feature.

With some attention to the exposure of your images and use of some of the techniques described here, you can achieve a correctly exposed image nearly all of the time.  After mastering the essentials of exposure, you will have more keepers and fewer images in the virtual trash can, and you can even begin to break the rules for artistic effect.

Beyond the Auto Mode [Encore Publication]: Take control of your images by learning to manually set exposure, focus, and more

Travel photography is so exciting and satisfying in part because it requires us to capture every kind of image in all kinds of shooting environments.  You could be heading out to shoot landscapes when suddenly a rare sighting of an animal transforms your activity into a wildlife shoot.  Or you may be on the road for your next destination when you stumble upon a colorful local festival, and now you’re shooting portraits of the revelers.  This rich diversity of subjects also creates one of the biggest challenges for travel photographers: how to be prepared for anything that comes our way.  For beginning photographers there is some comfort in using the Auto mode that nearly every camera offers.  After all, we’re more likely to get an acceptable shot this way, when the subject turns quickly from fast action to landscapes to the low light of evening, or to an indoor performance.  But in most cases, your camera’s Auto mode, which attempts to make its best guesses as to what settings to use given existing conditions, will yield only acceptable photos and not the striking and memorable images we’re after.

There is a better way.  Take control of your images by learning how to manually set your exposure, focus, and other aspects of your photo.  All advanced point-and-shoot cameras and all mirrorless and DSLR cameras allow you to set most functions manually.  Even some basic point-and-shoot models have a way to go manual, but often this will involve options buried deep in a menu somewhere.  And there are apps available for both iOS and Android smart phones that allow you to take manual control over your phone’s camera.  I use an iPhone 6S, and I’ve found the “ProCam 4” app to work very nicely for providing control over the phone’s camera setting for exposure, focus, and flash.  You can find it for less than $5 on the Apple App Store: ProCam 4 App.  Even without using an app, most smart phone cameras do allow you to override the automatic settings by clicking on the part of the image you want to be in focus and used for the exposure setting; usually you can also set the exposure based on a different area of the image from the area that you want to be in focus.  But the dedicated apps will give you greater control, as they allow you to choose the shutter speed, aperture, and ISO for each shot.

For this image of a whirling dervish in Goreme, Turkey, I wanted to blur the dancer so as to give a sense of the continual turning motion in the ceremony, so I used my camera’s shutter-priority exposure mode and selected a slower shutter speed.  Buy this photo

The key to successfully using your camera’s manual settings is to learn how they work and to practice at home, long before you actually take a trip.  Like anything else, selecting the settings we want on a camera takes practice.  In this digital era, it’s easier to learn because you can see the results of each setting immediately on your camera’s screen.  So dig out that camera user guide, or find it online, or search for a good tutorial.  But do learn how to adjust the key settings manually.

The first manual setting every photographer should learn is how to turn off your camera’s flash.  This sounds very basic, but I’m always amazed to see so many flashes going off in inappropriate places: museums that don’t allow flash photography, cultural performances, sports stadiums where the subject is thousands of feet away from the camera (the flash will only provide acceptable lighting for a few dozen feet, at most), and even the shy octopus exhibit at our local aquarium.  Believe me, you do not want to flash the octopus.  So learn how to turn your flash off, and be sure you actually do turn it off when you’re in a venue where flash is inappropriate or won’t help your image be better exposed.  Remember that glass reflects light, so you don’t want your flash on when shooting through windows of a vehicle or the glass windows of animal enclosures at zoos or aquariums.

Next, learn how to set your camera’s exposure manually.  The light meters built into today’s cameras are very smart, but they are also easily fooled by tricky lighting conditions.  The most common problem is backlighting.  If your subject is lit from behind, as many outdoor subjects are, your camera’s auto mode will likely expose for the brighter background and will leave your main subject underexposed.  You can adjust for this is several ways.  It may be good enough to just use your camera’s exposure compensation button to dial in, say, one extra stop of exposure.  Use your camera’s LCD screen and (if it has one) the histogram, to see how the subject is exposed with varying levels of compensation.  In some cases, you can use fill flash to fix backlighting problems.  To do so, manually turn on your camera’s flash, or attach a separate flash unit, and choose the setting for “fill flash” or “balanced TTL” (through the lens) flash mode.  Again, check exposure using your camera’s screen and histogram.  I find I usually get good results in tricky lighting conditions by using my camera’s spot metering mode, which tells the camera’s meter to use only the very center (or whatever area I select) of the image when choosing the exposure.

Other than allowing you to properly expose your main subject, manually setting the exposure also gives you control over what combination of shutter speed (how long the exposure lasts), aperture (how wide the lens is open), and ISO (how sensitive the camera is to light) you want for each shot.  If you’re shooting fast moving action like sports or wildlife, you will likely want to choose a fast shutter speed to freeze the motion (unless you want a blur effect as an artistic choice).  If you’re photographing a waterfall or sky and want to get some nice blurring of the water and/or clouds, you will probably want to choose a slower shutter speed.  Many times you want only certain parts of the image to be in focus.  A wide aperture (low F-stop number such as f/1.8) will give you a shallow depth-of-field, allowing only one part of the image to be in focus and blurring the other parts.  Conversely, a narrow aperture (high F-stop number such as f/16) will allow all parts of the photo to be in focus.  The final element determining exposure is the sensitivity of the camera’s sensor, measured by an ISO number.  Select a higher ISO (such as 1600 or above) only when you really need the extra sensitivity for very low-light subjects when a longer shutter speed or wider aperture is not suitable.  When you use very high ISO settings, the image will tend to have a lot of noise.  Today’s cameras are getting better at limiting noise at high ISO settings, and there are ways to reduce some of the effects of the noise using post-processing software, so my approach is to use as high an ISO as is required after considering the range of available shutter speeds and apertures.

To capture these professional beach volleyball players in sharp focus and to freeze the moment, I selected single-focus-point focus mode and chose the exact spot in the viewfinder where the players would be positioned, and also used my camera’s shutter-priority exposure mode to select a very fast shutter speed.  Buy this photo

The other major type of manual setting that you need to know how to use is focus.  Most cameras today do a pretty good job of choosing the right part of the image to focus on, but they often need some help from the photographer.  From simple smart phone cameras through professional DSLRs, the autofocus function almost always lets the photographer select what part of the image they want to be in focus.  If you keep your camera in fully autofocus mode and don’t help by selecting where your main subject is, it may very well guess incorrectly and put another part of the image as the center of focus.  So, learn how to select the focus point even while letting your camera’s autofocus mechanism actually choose the focus distance.  Sometimes a camera’s autofocus capability may not work for the conditions under which you’re shooting, and in these cases you need to turn off autofocus completely, and focus in manual mode.  Some instances when this is necessary are when shooting in very low light conditions, or when shooting in poor contrast environments (for example, your subject’s texture looks a lot like that of its background, or you’re shooting into the bright sun).  In these cases, turn off the autofocus function and adjust focus manually until the subject looks sharp.

It’s still fine to walk around during your travels with your camera set in fully Auto mode, just in case something very unexpected comes up.  But do know how to set the main functions manually so you’ll get the best possible images in the 95% of the shooting situations when you do have time to set up first.

Bracketing: Hedging Your Bets [Encore Publication]: In challenging shooting conditions, exposure bracketing is a great insurance policy

In the old film days of photography, it would be days or even weeks after shooting before we could see the results.  I would routinely use a procedure called “bracketing” to make a series of shots, each at a slightly different exposure, to increase the odds that one would come out decently exposed.  Even today, when digital photography allows us to see the results immediately, there are two good reasons to employ the exposure bracketing technique: 1) it can be hard to assess on a small LCD screen in bright daylight and while in the excitement of shooting whether the exposure is really correct, and 2) when the contrast between the brighter and dimmer parts of the scene is high we may want to stitch several different exposures together using software to create a high dynamic range (HDR) image later.

Tricky subjects, like this tiny Svalbard reindeer against a glacier background, benefit greatly from exposure bracketing.  From a series of 5, 7, or even 9 images shot at slightly different exposures, you can choose the one with the correct exposure for the conditions.  Buy this photo

So there are still good reasons to use exposure bracketing, and fortunately, it is quite easy to employ this technique.  Here’s how.

If possible, mount your camera on a tripod when using bracketing so it won’t move between exposures.  Then you can combine several of the exposures into an HDR image later if desired.

If your camera has a bracketing button or menu item, use it to specify how many shots you want to take (I usually shoot 5 or 7 different exposures when bracketing) and how much you want to vary the exposure between each shot and the next (often I choose a 1-stop difference).  If your camera lacks this feature, you can still use bracketing by manually adjusting the exposure between each shot and the next; just use your camera’s exposure compensation control to dial in first -2 stops, then -1 stop, then 0, then +1 stop, and finally +2 stops.

I like to set my camera for continuous shooting while bracketing.  That way, I just hold down the remote shutter release and the camera shoots all 5 or 7 exposures in rapid succession.  But it’s fine to shoot each frame individually in single release mode, if you prefer.

There are some subtleties to think about when employing exposure bracketing.  Some cameras let you choose whether to vary the aperture, the shutter speed, or the ISO setting, while holding the other two settings constant.  In most cases, I prefer to vary the shutter speed and hold the aperture and ISO settings constant, because changing the aperture affects the images’s depth-of-field, and changing the ISO setting can affect the noise in the image.

Later, during post-processing, you review the images and choose the one that is properly exposed.  Or if the scene is very high contrast, you can use photo editing software such as Lightroom or Photoshop to stitch several frames in your series together into an HDR image, which ensures good exposure from the brightest to the darkest tones in your photo.

Several exposures were shot using bracketing and then combined in Photoshop to create this HDR  image.  All tones from the darkest shadows on the mountain walls to the brightest highlights on the icebergs and lake are properly exposed in the final image.  Buy this photo

Decent Exposure [Encore Publication]: Mastering exposure is key to getting great images

Of all the primary elements a photographer controls–composition, focus, the moment the shutter is released, and of course the choice of the subject–none is more critical to making a great image than setting a proper exposure.  Some corrections to a poorly exposed image can be made in post-processing, and there are occasionally good artistic reasons to override the norms of exposure in order to evoke a certain mood in an image by making it darker or brighter than usual, but before we can effectively make these exceptional choices it is necessary to learn the basics of setting an appropriate exposure.

Let’s begin by defining exposure and the elements that comprise it.  Simply put, exposure refers to the amount of light that reaches the camera’s sensor and therefore how light or dark the resulting image will appear.  Four components together determine the exposure: 1) the brightness of the light reflecting off the subject and reaching the front of the lens, 2) the aperture setting on the lens (how wide or narrow is the opening of the lens), 3) the shutter speed setting (how long is the camera’s shutter open to allow light to strike the sensor), and 4) the sensitivity setting of the camera’s sensor.  We don’t always have control over the first component, but the other three are within our control using our camera’s settings.

Many photographers simply set their camera on Auto mode and let the camera’s built-in meter make its best guess as to how the image should be exposed.  That method can work well under certain conditions, but it is highly prone to errors.  For example, if your main subject is strongly backlit, the camera’s meter will expose for the average brightness in the scene and will underexpose the subject.  This is why so often we see underexposed photos of people standing outside in bright sunlight.

Although I compensated for the strong backlighting in this image of a Tibetan family enjoying a midday picnic, their faces are still quite shadowy, indicating a bit brighter exposure would have been better still.  Buy this photo

Fortunately, there are several easy methods to achieve a correct exposure even under challenging lighting conditions.  Here are a few that I use frequently:

  1. Set the camera’s metering mode to Spot Metering: By default most cameras’ metering systems use a sophisticated pattern-matching algorithm that measures how bright or dark each area of the image is and makes its best guess about a workable exposure based on similar scenes in the camera’s database.  Most cameras allow you to select a simpler metering mode called Spot Metering, that just measures the light at the central point in the image or another point that you select.  If you choose Spot Metering and select the measuring point to be right where your main subject is, you should get just the right exposure.
  2. Dial in some exposure compensation: Most cameras let you override the meter’s exposure setting by dialing in a compensation setting to lighten or darken the image.  If your subject is backlit, you will likely want to increase the exposure by one to two stops (each “stop” of additional exposure represents a doubling of the amount of light reaching the sensor).  The camera’s display should show something like “+1 EV” to alert you that you’ve dialed in 1 extra stop of exposure, and the number changes as you change the compensation setting.  Just be sure to set the exposure compensation back to zero when you’re done using it.
  3. Go fully manual: To gain complete control over your camera’s exposure settings, choose the meter’s Manual mode.  Then you can change all three exposure elements (shutter speed, aperture, and ISO) until the image appears properly exposed when you review it on your camera’s display.
  4. Use flash to increase the lighting on your main subject: One good way to achieve proper exposure with a backlit subject is to increase lighting on the subject itself, so that there is no longer such a difference in brightness between the subject and the background.  Your camera’s built-in flash may be strong enough to pull off this trick, but it often helps to have a more powerful flash unit with you.  There are some other reasons why you may not want to use flash as a main source of light on your subject, so this method should be used sparingly.  A reflector can be used instead of flash to reflect some of the sun’s light onto the front of your subject.

For this photo shoot with a musician friend, I shot into the light so she wouldn’t have to squint into the sun and also so that we’d have a beautiful rim light from the sun around her hair.  To pull this off, I used manual mode and selected the proper exposure for her face.  I employed a reflector to bounce some sunlight back onto her face and trumpet.  [Client image not for sale.]

Similar methods can be used for other challenging lighting conditions besides backlighting.  If the subject is a brighter or darker color than the “neutral gray” your camera’s meter uses for a standard, then you need to dial in more or less exposure as appropriate.  My black cat Dragonfly, for example, requires an especially dark exposure to override the meter from thinking he’s a gray cat and choosing too bright an exposure.  Similarly, a white polar bear will need additional exposure to stop the meter from underexposing what it assumes to be a gray bear.

When photographing a black subject, reduce the exposure to compensate for the light meter’s mistaken assumption that the subject is a neutral gray color.  Buy this photo

Whatever method you use to choose your exposure, be sure to take a look at the resulting image using your camera’s monitor.  Does the main subject appear to be properly exposed, or is it still too dark or perhaps too bright?  If your camera offers a histogram display, learn how it works and use it to check your exposure in tricky lighting conditions.  I’ll write a future post specifically about the histogram, as it is a very useful and often overlooked feature.

With some attention to the exposure of your images and use of some of the techniques described here, you can achieve a correctly exposed image nearly all of the time.  After mastering the essentials of exposure, you will have more keepers and fewer images in the virtual trash can, and you can even begin to break the rules for artistic effect.

Beyond the Auto Mode: Take control of your images by learning to manually set exposure, focus, and more [Encore Publication]

Travel photography is so exciting and satisfying in part because it requires us to capture every kind of image in all kinds of shooting environments.  You could be heading out to shoot landscapes when suddenly a rare sighting of an animal transforms your activity into a wildlife shoot.  Or you may be on the road for your next destination when you stumble upon a colorful local festival, and now you’re shooting portraits of the revelers.  This rich diversity of subjects also creates one of the biggest challenges for travel photographers: how to be prepared for anything that comes our way.  For beginning photographers there is some comfort in using the Auto mode that nearly every camera offers.  After all, we’re more likely to get an acceptable shot this way, when the subject turns quickly from fast action to landscapes to the low light of evening, or to an indoor performance.  But in most cases, your camera’s Auto mode, which attempts to make its best guesses as to what settings to use given existing conditions, will yield only acceptable photos and not the striking and memorable images we’re after.

There is a better way.  Take control of your images by learning how to manually set your exposure, focus, and other aspects of your photo.  All advanced point-and-shoot cameras and all mirrorless and DSLR cameras allow you to set most functions manually.  Even some basic point-and-shoot models have a way to go manual, but often this will involve options buried deep in a menu somewhere.  And there are apps available for both iOS and Android smart phones that allow you to take manual control over your phone’s camera.  I use an iPhone 6S, and I’ve found the “Manual” app to work very nicely for providing control over the phone’s camera setting for exposure, focus, and flash.  You can find it for less than $2 on the Apple App Store: https://itunes.apple.com/us/app/manual-custom-exposure-camera/id917146276?mt=8.  Even without using an app, most smart phone cameras do allow you to override the automatic settings by clicking on the part of the image you want to be in focus and used for the exposure setting; usually you can also set the exposure based on a different area of the image from the area that you want to be in focus.  But the dedicated apps will give you greater control, as they allow you to choose the shutter speed, aperture, and ISO for each shot.

For this image of a whirling dervish in Goreme, Turkey, I wanted to blur the dancer so as to give a sense of the continual turning motion in the ceremony, so I used my camera’s shutter-priority exposure mode and selected a slower shutter speed.  Buy this photo

The key to successfully using your camera’s manual settings is to learn how they work and to practice at home, long before you actually take a trip.  Like anything else, selecting the settings we want on a camera takes practice.  In this digital era, it’s easier to learn because you can see the results of each setting immediately on your camera’s screen.  So dig out that camera user guide, or find it online, or search for a good tutorial.  But do learn how to adjust the key settings manually.

The first manual setting every photographer should learn is how to turn off your camera’s flash.  This sounds very basic, but I’m always amazed to see so many flashes going off in inappropriate places: museums that don’t allow flash photography, cultural performances, sports stadiums where the subject is thousands of feet away from the camera (the flash will only provide acceptable lighting for a few dozen feet, at most), and even the shy octopus exhibit at our local aquarium.  Believe me, you do not want to flash the octopus.  So learn how to turn your flash off, and be sure you actually do turn it off when you’re in a venue where flash is inappropriate or won’t help your image be better exposed.  Remember that glass reflects light, so you don’t want your flash on when shooting through windows of a vehicle or the glass windows of animal enclosures at zoos or aquariums.

Next, learn how to set your camera’s exposure manually.  The light meters built into today’s cameras are very smart, but they are also easily fooled by tricky lighting conditions.  The most common problem is backlighting.  If your subject is lit from behind, as many outdoor subjects are, your camera’s auto mode will likely expose for the brighter background and will leave your main subject underexposed.  You can adjust for this is several ways.  It may be good enough to just use your camera’s exposure compensation button to dial in, say, one extra stop of exposure.  Use your camera’s LCD screen and (if it has one) the histogram, to see how the subject is exposed with varying levels of compensation.  In some cases, you can use fill flash to fix backlighting problems.  To do so, manually turn on your camera’s flash, or attach a separate flash unit, and choose the setting for “fill flash” or “balanced TTL” (through the lens) flash mode.  Again, check exposure using your camera’s screen and histogram.  I find I usually get good results in tricky lighting conditions by using my camera’s spot metering mode, which tells the camera’s meter to use only the very center (or whatever area I select) of the image when choosing the exposure.

Other than allowing you to properly expose your main subject, manually setting the exposure also gives you control over what combination of shutter speed (how long the exposure lasts), aperture (how wide the lens is open), and ISO (how sensitive the camera is to light) you want for each shot.  If you’re shooting fast moving action like sports or wildlife, you will likely want to choose a fast shutter speed to freeze the motion (unless you want a blur effect as an artistic choice).  If you’re photographing a waterfall or sky and want to get some nice blurring of the water and/or clouds, you will probably want to choose a slower shutter speed.  Many times you want only certain parts of the image to be in focus.  A wide aperture (low F-stop number such as f/1.8) will give you a shallow depth-of-field, allowing only one part of the image to be in focus and blurring the other parts.  Conversely, a narrow aperture (high F-stop number such as f/16) will allow all parts of the photo to be in focus.  The final element determining exposure is the sensitivity of the camera’s sensor, measured by an ISO number.  Select a higher ISO (such as 1600 or above) only when you really need the extra sensitivity for very low-light subjects when a longer shutter speed or wider aperture is not suitable.  When you use very high ISO settings, the image will tend to have a lot of noise.  Today’s cameras are getting better at limiting noise at high ISO settings, and there are ways to reduce some of the effects of the noise using post-processing software, so my approach is to use as high an ISO as is required after considering the range of available shutter speeds and apertures.

To capture these professional beach volleyball players in sharp focus and to freeze the moment, I selected single-focus-point focus mode and chose the exact spot in the viewfinder where the players would be positioned, and also used my camera’s shutter-priority exposure mode to select a very fast shutter speed.  Buy this photo

Next, learn how to set your camera’s exposure manually.  The light meters built into today’s cameras are very smart, but they are also easily fooled by tricky lighting conditions.  The most common problem is backlighting.  If your subject is lit from behind, as many outdoor subjects are, your camera’s auto mode will likely expose for the brighter background and will leave your main subject underexposed.  You can adjust for this is several ways.  It may be good enough to just use your camera’s exposure compensation button to dial in, say, one extra stop of exposure.  Use your camera’s LCD screen and (if it has one) the histogram, to see how the subject is exposed with varying levels of compensation.  In some cases, you can use fill flash to fix backlighting problems.  To do so, manually turn on your camera’s flash, or attach a separate flash unit, and choose the setting for “fill flash” or “balanced TTL” (through the lens) flash mode.  Again, check exposure using your camera’s screen and histogram.  I find I usually get good results in tricky lighting conditions by using my camera’s spot metering mode, which tells the camera’s meter to use only the very center (or whatever area I select) of the image when choosing the exposure.

Other than allowing you to properly expose your main subject, manually setting the exposure also gives you control over what combination of shutter speed (how long the exposure lasts), aperture (how wide the lens is open), and ISO (how sensitive the camera is to light) you want for each shot.  If you’re shooting fast moving action like sports or wildlife, you will likely want to choose a fast shutter speed to freeze the motion (unless you want a blur effect as an artistic choice).  If you’re photographing a waterfall or sky and want to get some nice blurring of the water and/or clouds, you will probably want to choose a slower shutter speed.  Many times you want only certain parts of the image to be in focus.  A wide aperture (low F-stop number such as f/1.8) will give you a shallow depth-of-field, allowing only one part of the image to be in focus and blurring the other parts.  Conversely, a narrow aperture (high F-stop number such as f/16) will allow all parts of the photo to be in focus.  The final element determining exposure is the sensitivity of the camera’s sensor, measured by an ISO number.  Select a higher ISO (such as 1600 or above) only when you really need the extra sensitivity for very low-light subjects when a longer shutter speed or wider aperture is not suitable.  When you use very high ISO settings, the image will tend to have a lot of noise.  Today’s cameras are getting better at limiting noise at high ISO settings, and there are ways to reduce some of the effects of the noise using post-processing software, so my approach is to use as high an ISO as is required after considering the range of available shutter speeds and apertures.

To capture these professional beach volleyball players in sharp focus and to freeze the moment, I selected single-focus-point focus mode and chose the exact spot in the viewfinder where the players would be positioned, and also used my camera’s shutter-priority exposure mode to select a very fast shutter speed.  Buy this photo on my website

The other major type of manual setting that you need to know how to use is focus.  Most cameras today do a pretty good job of choosing the right part of the image to focus on, but they often need some help from the photographer.  From simple smart phone cameras through professional DSLRs, the autofocus function almost always lets the photographer select what part of the image they want to be in focus.  If you keep your camera in fully autofocus mode and don’t help by selecting where your main subject is, it may very well guess incorrectly and put another part of the image as the center of focus.  So, learn how to select the focus point even while letting your camera’s autofocus mechanism actually choose the focus distance.  Sometimes a camera’s autofocus capability may not work for the conditions under which you’re shooting, and in these cases you need to turn off autofocus completely, and focus in manual mode.  Some instances when this is necessary are when shooting in very low light conditions, or when shooting in poor contrast environments (for example, your subject’s texture looks a lot like that of its background, or you’re shooting into the bright sun).  In these cases, turn off the autofocus function and adjust focus manually until the subject looks sharp.

It’s still fine to walk around during your travels with your camera set in fully Auto mode, just in case something very unexpected comes up.  But do know how to set the main functions manually so you’ll get the best possible images in the 95% of the shooting situations when you do have time to set up first.
