Abstract (en)
A method of preparing a tabular silver halide emulsion involves growing a silver halide seed emulsion in which tabular silver halide grains having an aspect ratio of 2 to 12 account for 50% to 100% of a total projected area of all silver halide grains of the seed emulsion, to prepare a grown tabular silver halide emulsion in which tabular silver grains having an aspect ratio of 3 to 40 account for 50% to 100% of a total projected area of all silver halide grains of the grown emulsion.
