Abstract
There is disclosed a silver halide photographic material comprising a support having provided thereon at least one silver halide photosensitive emulsion layer, wherein said silver halide photosensitive emulsion layer contains silver iodobromide grains having a silver iodide content of 0.1 to 4.0 mol %, said grains containing 5.times.10.sup.-9 to 1.times.10.sup.-6 mole of an iridium compound and 5.times.10.sup.-8 to 1.times.10.sup.-3 mole of an iron compound per mole of the silver halide in said silver iodobromide grains, and a method for forming an image comprising the silver halide photographic meterial to a high-irradiation short-duration exposure followed by development. The photographic material has high speed, high contrast and is outstanding in handling properties under a safelight.
