Abstract
A high bromide {111} tabular grain emulsion is disclosed in which most of the tabular grains exhibit silver salt epitaxy at a single site. Most of the silver halide epitaxy sites contact an edge region of the tabular grains. These emulsions exhibit chemical sensitization by the epitaxy and surprising lower levels of desensitization by spectral sensitizing dyes.
