Abstract
A method of a processing of a silver halide color photographic material is disclosed. The process comprises a step of developing the exposed color photographic material and a step of treating the developed color photographic material with a bleach-fixing solution. The bleach-fixing solution contains an organic acid ferric complex. At least one layer of the emulsion layers of the photographic material contains silver halide grains containing from 0.5 to 25 mol % of silver iodide. The total dry-thickness of the photographic component layers contained in the photographic material is from 8 to 25 .mu.m and the swelling rate T1/2 of the photographic component layers is not more than 25 sec. The method is suitable for rapid processing of the fine grain-type high-speed silver iodide-containing color photographic material. The method uses a bleach-fixing bath enabling the rapid processing of the high-speed color photographic material.
