摘要:
A silver halide photographic emulsion is disclosed, comprising silver halide grains wherein at least 80% of a total grain projected area is accounted for by tabular grains, the tabular grains having an average aspect ratio of at least 12, a variation coefficient of grain diameter of less than 30%, an average overall surface iodide content of 5 to 15 mol % and an average surface iodide content in the vicinity of corners of the grains of less than 3 mol %; and the tabular grains further having a shallow electron trap center in the peripheral region of the grain.
