<p>A chemically sensitized high chloride tabular grain emulsion is disclosed. The tabular grains have {100} major faces. Chemically sensitized silver halide epitaxial deposits containing less than 75 percent of the chloride ion concentration of the tabular grains and accounting for less than 20 mole percent of total silver are located at one or more of the corners of the tabular grains. The emulsions are prepared by first forming the host tabular grains, epitaxially depositing silver halide selected to contain less than 50 percent of the chloride ion concentration of the tabular grains, adsorbing a photographically useful compound to the surfaces of the silver halide epitaxial deposits, and chemically digesting the emulsion. <IMAGE></p> |
