ABSTRACT:
A process for producing a silver halide photographic material and a photographic material produced thereby are disclosed. The process comprises the steps of (1) forming a seed emulsion comprising silver halide seed grains, (2) growing the seed grains to prepare a silver halide photographic emulsion by supplying a silver ion component and a halide ion component to the mother liquid of the seed emulsion, (3) coating and drying the photographic emulsion on a support to form the silver halide emulsion layer, and at least a period during the step for growing the seed grains is performed in the presence of silver iodide grains, and an oxidant capable of converting metallic silver to silver ions is added at a time during the step for growing the seed grains.
