ABSTRACT:
A method for preparing a silver halide photographic emulsion containing silver halide grains , each of which has two or more phases different in the silver halide composition, comprising a step of growing silver halide grains, in which said silver halide grains are grown by supplying a solution of water-soluble silver salt and a solution of water-soluble halide, wherein fine grains of silver halide having a solubility product smaller than that of silver halide grains present in the course of growing silver halide grains are made present in the silver halide emulsion at a time during the grain-growth, iridium ions being individually added at a time when or after starting the grain-growth.
