ABSTRACT:
A light-sensitive silver halide photographic material having silver halide emulsion layers on a support, wherein at least one layer of said silver halide emulsion layers contains surface latent image type mono-dispersed silver halide grains, and 50% or more of the silver halide grains contained in said at least one silver halide emulsion layer are regular surface latent image type mono-dispersed silver halide grains of tetradecahedral crystals whose external surfaces have crystal faces with Miller indices (100) and (111), the area ratio of said (100) face and said (111) face satisfying the relation represented by the correlation formula (I) shown below:
