Calibration Time, Come On! [Encore Publication]: Why you should color-calibrate your display devices and how to do it

We tend to take for granted that the colors we perceive when we look at a scene will be captured faithfully by our camera’s sensor and the lens in front of it, and then rendered accurately in every stage of processing thereafter, from the memory card to the computer and to all our displays including laptops, tablets, smartphones, TVs, projectors, and even on these same types of displays owned by our friends with whom we share our images.  (We also expect prints made from our images to faithfully reproduce the colors from our camera’s sensor, but that is a story for another day.)

As photographers, we want to ensure the colors in our final images reflect as best we can the original colors we perceived when first framing the scene.  With proper color-calibration of the display screens we use to process our images, we can keep the colors as true and accurate as possible.  Buy this photo

The reality is that every step of the process of capturing, processing, and sharing an image leads to changes in the rendition of the colors.  No device can fully represent every intensity of every color that the human eye can see.  Camera manufacturers go to great lengths to ensure the colors captured by the camera’s sensor are as accurate as possible when you attach a lens made by the same company.  And when you use software such as Lightroom or Photoshop to post-process your images, you may take great pains to ensure the colors you see on your screen look very close to what you remember you saw when you shot the image in the first place.  But without careful attention, the final image we see later on our various display screens can look very different from device to device.  That’s because every type of display, and even every individual screen, has a unique way of representing every color.  So your PC’s monitor will display any given color just a bit differently than your phone’s screen will show that color.  And your friend’s phone’s screen will look a bit different, still (even if it’s the exact same brand and model as yours).

Fortunately, there is a simple and quite affordable way to standardize the representation of colors across all your devices.  It’s called color calibration, and for less than the cost of a good polarizing filter, say about $100, you can purchase a little doodad that can calibrate all your displays.  I use the X-Rite ColorMunki, which can be had for about $110 at retail.

To use a color calibration device, you install some software on your display(s) and then place the device on your display screen.  The software cycles the screen through displaying a wide range of colors, which are read and recorded by the calibration device.  Finally, the needed adjustments to bring your screen’s settings into line so they render colors as accurately as possible are saved in a special file.  From this point on, whenever your display device is started up, it reads the configuration information in that file and renders colors as closely to their actual appearance as it is physically capable of doing.

Because our eyes perceive colors differently in different ambient light conditions, you’ll want to have your calibration device take an ambient light reading for the typical lighting conditions that will be present while you’re using each display.  For example, if you use your laptop PC mostly when bright daylight is streaming into your kitchen, you’ll want to calibrate when those conditions are present.  You can even save different versions of the configuration file for different lighting conditions.

And because display devices do change over time, it’s a good idea to re-calibrate each device every few weeks to control for that.

If you’re serious about your photography, you want your images to look great not only on your own display screen(s), but also when viewed by other people on other types of devices or on the printed page.  Using a reliable color-calibration device helps ensure the colors in your images remain as accurate as possible through all the stages of processing and sharing until they leave your personal control.  This is a good practice that all photographers should employ.

Because our eyes perceive colors differently in different ambient light conditions, you’ll want to have your calibration device take an ambient light reading for the typical lighting conditions that will be present while you’re using each display.  For example, if you use your laptop PC mostly when bright daylight is streaming into your kitchen, you’ll want to calibrate when those conditions are present.  You can even save different versions of the configuration file for different lighting conditions.

And because display devices do change over time, it’s a good idea to re-calibrate each device every few weeks to control for that.

If you’re serious about your photography, you want your images to look great not only on your own display screen(s), but also when viewed by other people on other types of devices or on the printed page.  Using a reliable color-calibration device helps ensure the colors in your images remain as accurate as possible through all the stages of processing and sharing until they leave your personal control.  This is a good practice that all photographers should employ.

Calibration Time, Come On! [Encore Publication]: Why you should color-calibrate your display devices and how to do it

We tend to take for granted that the colors we perceive when we look at a scene will be captured faithfully by our camera’s sensor and the lens in front of it, and then rendered accurately in every stage of processing thereafter, from the memory card to the computer and to all our displays including laptops, tablets, smartphones, TVs, projectors, and even ono these same types of displays owned by our friends with whom we share our images.  (We also expect prints made from our images to faithfully reproduce the colors from our camera’s sensor, but that is a story for another day.)

As photographers, we want to ensure the colors in our final images reflect as best we can the original colors we perceived when first framing the scene.  With proper color-calibration of the display screens we use to process our images, we can keep the colors as true and accurate as possible.  Buy this photo

The reality is that every step of the process of capturing, processing, and sharing an image leads to changes in the rendition of the colors.  No device can fully represent every intensity of every color that the human eye can see.  Camera manufacturers go to great lengths to ensure the colors captured by the camera’s sensor are as accurate as possible when you attach a lens made by the same company.  And when you use software such as Lightroom or Photoshop to post-process your images, you may take great pains to ensure the colors you see on your screen look very close to what you remember you saw when you shot the image in the first place.  But without careful attention, the final image we see later on our various display screens can look very different from device to device.  That’s because every type of display, and even every individual screen, has a unique way of representing every color.  So your PC’s monitor will display any given color just a bit differently than your phone’s screen will show that color.  And your friend’s phone’s screen will look a bit different, still (even if it’s the exact same brand and model as yours).

ProCam 4 Update: Still the best iOS camera app I’ve ever used

I’ve been using the ProCam 4 iOS app for nearly two months now, and today’s post provides a brief update to my previous product review.  My original review can be found just after the quick update.

My already high opinion of ProCam 4 has only been enhanced further after spending several weeks using it in the field.  It’s rare to find an app that combines such a high degree of functionality with such an easy-to-use interface.  While I don’t use the in-app editing features, preferring to use Adobe Lightroom for my post-processing whenever possible, I’ve been using most of ProCam 4’s other powerful features including the manual control over ISO, shutter speed, white balance, and flash; capture in RAW+JPEG formats; exposure bracketing; and the different shutter release options.  Everything is pretty intuitive to use and it’s a joy to shoot with because all the main features are readily accessible “on the fly”.  The resulting images are higher quality than those I’ve been able to obtain with the same iPhone 6S camera hardware controlled by other apps.  Overall, I continue to believe ProCam 4 is the best iOS camera app I’ve seen.

Note to Android users: As far as I know, ProCam 4 still is not available for Android devices.

One more note: With this week’s release of iOS 10.2, there is some enhanced support for RAW capture, but the built-in Apple Camera app still does not support RAW mode, so you will continue to need to use a third-party iOS camera app to capture images in RAW.  I recommend ProCam, but there are many choices out there.

My original product review of the ProCam 4 app follows:

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 “ProCam 4”, which is by far the best iOS camera app I’ve ever used.  Like the “Manual” camera app that I’ve been using for years, ProCam 4 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 Mode).  And both of these camera apps display a histogram to assist in setting exposure properly.  

But ProCam 4 offers far more functionality than does the Manual app or any other iOS camera app I’ve tried.  Here is a partial list of some of my favorite additional features:

  • 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.
  • Editing Options: This app provides many advanced in-camera editing tools and filters.

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 ProCam 4 are vastly improved compared to using the phone’s native camera app.  At $4.99 to purchase via the iTunes Store, this app is a great buy and a serious enhancement to the iPhone’s built-in camera.
