Summary: Images of a ColorChecker Classic were taken in direct sunlight and shade. Consistency of color reproduction across lighting conditions was best when using ColorChecker Passport profiles made specifically for each situation. The general-purpose dual-illuminant Adobe Standard profile for the Sony A6500 camera gave less color consistency between sun and shade images. However, the effect of camera profile on consistency, as measured by CIEDE2000, was not large. Average CIEDE2000 between sun and shade images was approximately 2.0 for the Passport profiles; a value that is well above the threshold of just noticeable difference when colors are compared side-by-side. It is likely that no profiling procedure can produce absolute color consistency across different illuminants and shooting situations, given current camera sensor technology.
