摘要：
A method for producing a silver halide emulsion in which grains having an aspect ratio of from 1.5 to 100 occupy from 75 to 100% of the total projected area of all grains comprising at least nucleation, ripening and grain growth processes in a dispersion medium solution containing water and a dispersion medium, wherein the dispersion medium solution contains low molecular weight gelatin having a molecular weight of from 1,000 to 70,000 at least during a nucleation process and chemically modified gelatin having a chemical modification rate of the amino group of from 15% to 100% at least during a grain growth process.
