ABSTRACT:
Silver halide emulsions of limited iodide content, processes for the preparation of these emulsions, photographic elements incorporating these emulsions, and processes for the use of the photographic elements are disclosed. In the emulsions silver halide grains predominantly bounded by {111} crystal faces and containing insufficient iodide to direct silver salt epitaxy to selected surface sites of the grains are present. Silver salt is epitaxially located on and substantially confined to selected surface sites of the silver halide grains, this being accomplished by the use of an adsorbed site director.
