High chloride silver iodohalide emulsions containing an increased proportion of iodide

A photographic silver halide emulsion comprised of a high chloride silver iodohalide grain structure having a face centered cubic rock salt type crystal structure in which the proportions of chloride, bromide and iodide ions are chosen to lie within the boundary defined by A', B' C and D in FIG. 1, where A' indicates a 1 mole percent higher iodide concentration than A and B' indicates a 1 mole percent higher iodide concentration than B.
