A process is disclosed for the continuous formation of radiation- sensitive silver halide emulsions. In the course of reacting a silver salt with a halide salt in the presence of a peptizer to form a radiation- sensitive silver halide emulsion a portion of the emulsion is withdrawn continuously from the reaction chamber while silver halide grain formation is occurring. The silver halide grains are formed in the presence of a sulfur-containing silver halide ripening agent, while the total halide ion concentration is concurrently controlled and maintained at less than 0.01 molar.
