摘要： The present invention relates to a silver halide emulsion subjected to selenium sensitization in the presence of a palladium compound in an amount of 5.times.10.sup.-5 mol or more per mol of a silver halide. In addition to selenium sensitization, the emulsion may be subjected to sulfur sensitization and/or gold sensitization. In a process of manufacturing the silver halide emulsion, the palladium compound is preferably added to the emulsion before chemical sensitization.
