A corner development type silver halide photographic emulsion is disclosed, wherein the silver halide crystals in the silver halide emulsion are cubic or tetradecahedral grains having at least substantial (100) planes and the emulsion is controlled so that at least 70% of developed silver halide crystals (grains), which are observed on applying a light exposure of 1/50 second to the emulsion under the light-exposure condition corresponding to (maximum density --minimum density).times.3/4 of the silver image in the characteristic curve of the emulsion obtained by the developer, developing under the development condition which are used for processing a photographic light-sensitive material formed by coating the emulsion on a support, and stopping the development with an aqueous solution of 5% glacial acetic acid just after the initiation of the development, are developed at the corners of the cubic or tetradecahedral crystals or at the vicinity of the corners.
