ABSTRACT:
A color photographic material having three light-sensitive silver halide emulsion layers separately sensitized to different regions of the spectrum and containing an each colorless coupler for the production of partial color images, is partly fogged in one of said layers to produce on color development in unexposed areas a color fog with a density of between 0.25 and 0.75 suited to compensate for undesired side densities of the image dye in one or more of the other of said layers.
