ABSTRACT:
Converted-halide photographic emulsions and elements are disclosed containing composite silver halide crystals. The composite crystals are comprised of multifaceted, radiation-sensitive silver iodide crystals. Silver halide crystals at least partially converted from silver chloride to silver bromide form epitaxial junctions with the silver iodide crystals. At least half of the facets of the silver iodide crystals are substantially free of epitaxial silver chloride, and the converted silver halide crystals are limited to less than 75 mole percent, based on the total silver halide forming the composite crystals.
