It’s a Color Checker Passport (or CCP) !
If you are not familiar with this device you are missing a great tool for calibrating exposure, white balance and accurate color with one or two clicks in the computer. And in any light. Never more do you need to guess at how the subject looked at the time of exposure.
It works in two ways: First, it may be used to establish a camera, lens, light profile for use in Photoshop, Lightroom or other software. You may establish these profiles for standard lighting situations that you may encounter such as daylight, studio flash or your favorite Speedlight and/or softbox combination.
When first photographed it may look like this:
In the computer software, use the ACR eyedropper tool to set white balance then set mid-tone, black and white values using the palette squares provided. Then save the file as a camera profile in your preferred post processing software. A bit of software is provided by the CCP from Xrite to do this.
Once the profile is loaded into your software, open the set of images you wish to adjust, click on the profile and voila, one or many more images can be simultaneously set.
Second, without a profile, white balance, tone values and color may still be set using the standard palette squares for any image and synchronized to a batch photographed in the same conditions.
With one click, this image:
Can be processed into this:
And with a little cropping, dust removal, dodging and burning you are all set! And the good thing- white balance, tone values and color are all standardized. No guessing or trying to remember how the subject and scene looked. Because our eyes play tricks on us and because people don’t see color the same, this makes our photography accurate.
If we want true-to-life accuracy, this is the tool to use.
