ColorChecker Gray Scale

The ColorChecker Gray Scale card is a full size version of the white, 18% gray and black reference squares used in the standard 24-patch ColorChecker. This target is scientifically engineered to provide a precise uniform surface that is spectrally neutral (reflects equal amounts of red, blue and green) in all lighting conditions.

Using the ColorChecker Gray Scale

Photographers can use the ColorChecker Gray Scale as the first reference shot in a series to easily correct image color under most lighting conditions by balancing on the mid tone gray value. For the studio photographer, the ColorChecker Gray Scale lets them quickly set up the proper studio lighting ratio between main and fill lights for capturing accurate color without a lot of after-the-fact manipulation. In addition, the ColorChecker Gray Scale provides reference values that can quickly be checked and used to adjust colors within most common photo processing software packages.
