PROBLEM TO BE SOLVED: To provide a silver halide emulsion having high sensitivity and high contrast, ensuring a small variation of sensitivity due to difference in humidity condition in exposure and excellent in the reciprocity law characteristics under high illuminance. SOLUTION: The silver halide emulsion has been chemically sensitized with a compound which releases a compound having a chalcogen atom-metal atom bond. COPYRIGHT: (C)2003,JPO
