ABSTRACT:
The present invention is to provide a method for uniforming a group of silver halide particles of a silver halide emulsion to be used in a silver halide photographic light-sensitive material into a group of particles which is monodispersive and whose crystal habit is tetradecahedral or octahedral so that the complication and instabilization of the conventional particles can be reduced to be processed. Namely, in a process for growing particles in which a water-soluble silver salt is added to a core emulsion and a silver halide is produced to add to the core, this method is to adjust the pAg values of an emulsion being applied to the abovementioned process to increase by not less than 0.3 multistepwise or continuously.
