Abstract
A silver halide having at least two halides of differing atomic numbers may successfully be produced with a more uniform halide distribution within certain zones or throughout the entire volume of the individual grain and from grain to grain, if a portion or the entire quantity of the halide of the higher atomic number is dissolved in an aqueous silver salt solution and the resulting solution is introduced at any stage into the emulsion preparation process.
