ABSTRACT:
A process is disclosed of preparing a photographically useful emulsion containing radiation-sensitive silver iodohalide grains. Silver halide grains having a face centered cubic rock salt crystal lattice structure are precipitated within an aqueous dispersing medium including a hydrophilic colloid peptizer. Iodide ion is introduced into the crystal lattice structure by introducing elemental iodine into the dispersing medium and maintaining the dispersing medium within a pH range of from 5 to 8.
