Abstract
A method for preparing silver halide emulsion grains by a crystal growth method comprising feeding fine silver halide grains to a reaction vessel containing seed crystals of a silver halide emulsion and dissolving the fine grains in the reaction vessel by Ostwald ripening to grow said seed crystals, wherein the fine grains are non-twinned crystal fine grains having substantially no twinning plane.
