ABSTRACT:
A radiation-sensitive silver halide emulsion is disclosed comprised of composite grains including host grains having predominantly {111} crystal faces, cuprous ions adsorbed to the {111} crystal faces of the host grains to act as a site director for subsequently deposited silver salt, and silver salt protrusions having their highest incidence adjacent at least one of the corners and edges of the host grains.
