ABSTRACT:
A method for color reversal processing of an imagewise exposed silver halide color photographic material comprising first developing in a black-and-white developing bath, next color developing in a color developing bath, and then desilvering in a bath having a bleaching ability. The black-and-white developing bath has a bromide concentration in the range of 0.025 to 0.1 mol/l and is used for the black-and-white development. Furthermore, in a preferred embodiment, the photographic material comprises at least one silver halide emulsion layer containing a silver halide emulsion comprising silver halide grains having an average grain size of 0.3 .mu.m or less. In accordance with the invention, the maximum densities of the developed color images are increased without lowering of the sensitivity and contrast.
