Two new ColorChecker targets geared for the professional digital photographer were announced this week by GretagMacbeth:
The ColorChecker White Balance card is a larger version of the white patch from the original, 24-patch ColorChecker, and is promised to be spectrally neutral under a variety of illuminants for use with the Custom/Preset WB function of digital cameras or RAW file processing software.
The three-step ColorChecker Grayscale card contains white, 18% reflectance gray and black strips, to aid in the establishing of scene contrast ratio in controlled-light shooting environments.
