Abstract
Disclosed are photographic elements comprising a silver halide emulsion having incorporated therein silver halide grains, wherein the grains are essentially tabular in morphology and have at least two parallel {100} major faces and substantially equivalent {111} corner faces or substantially equivalent {110} corner faces or substantially equivalent {110} side faces.

A photographic element comprising a support and a silver halide emulsion layer, the silver halide emulsion layer having incorporated therein silver halide grains, wherein the grains are essentially tabular in morphology and have two parallel {100} major faces, and {111} corner faces or {110} corner faces or {110} side faces, and wherein the corner or side faces are formed by non-epitaxial deposits of silver halide that protrude from the {100} major faces.
A photographic element comprising a support and a silver halide emulsion layer, the silver halide emulsion layer having incorporated therein silver halide grains wherein the grains comprise a base portion of silver halide having two parallel {100} major faces and, protruding from the {100} major faces, additional non-epitaxial silver halide that forms at least eight {111} or at least eight {110} faces, the {111} faces, when present, protruding from the corners of the {100} major faces and the {110} faces, when present, protruding from the sides of the major faces.
