Calibrite ColorChecker 18 Percent Grey Balance
Description
The ColorChecker Gray Balance is the largest gray balance chart in the range. It is the same size as the ColorChecker Classic, at 215.9 x 279.4mm.
Using the ColorChecker Gray Balance chart to measure the exposure of a reflective spot gives you confidence that your images will be exposed to their best. The ColorChecker Gray Balance chart is the wide version of the 18% reflectance gray reference panel of the standard 24-patch ColorChecker chart. The gray is scientifically formulated to provide a uniform, accurate, and spectrally neutral surface (i.e., it reflects equal amounts of red, blue, and green) under all types of lighting conditions.
