ABSTRACT:
A method of producing a silver halide emulsion and a silver halide photographic light-sensitive material containing the emulsion are disclosed. The silver halide emulsion comprises light-sensitive silver halide grains containing at least one of first silver halide phases and at least one of second silver halide phases. The method comprises the steps of (a) forming the first silver halide phases in the presence of substantially one kind of first fine silver halide grains, said first silver halide phases having a silver halide composition different from that of the first fine silver halide grains, and (b) forming the second silver halide phases by supplying second fine silver halide grains having a solubility product higher than that of the first fine silver halide grains.
