摘要：
A silver halide photographic material in which a silver iodobromide emulsion having an iodide content of 2 mole % or more and an organometallic salt functioning as a development inhibitor are employed in combination, whereby an improvements in graininess and sharpness of a developed image are achieved and high photographic speed is retained.A process for producing silver images using the silver halide photographic material is also disclosed.
