Khronos GroupによるTone Mapper

グレースケールのライティング前提？

Khronos PBR Neutral enables faithful reproduction of a product’s base color, hue and saturation when using PBR rendering under grayscale lighting, while eliminating HDR artifacts around highlights. It complements tone mappers such as ACES, which are intended for use with other types of content such as images with wide input color gamuts, or are used to achieve stylized artistic looks used in the film, visual effects, and gaming industries.
