Anotations

Scope note:

Photographic negatives that record on a single base the hue and lightness of a scene in values that are complementary in relation to the scene's actual perceived values; e.g., light blue is recorded as dark yellow. See "color separation negatives" for images in which each color is recorded on a physically separate negative.
