A method of treating silver chloride emulsions comprising providing a silver chloride emulsion, adding gold and sulfur chemical sensitizers, heating to chemically sensitize said emulsion, cooling to below about 50.degree. C., adding bromide to the emulsion and then after bromide addition adding spectral sensitizing dye.
A method of imaging comprising providing a photographic element, wherein said element comprises at least one layer of an emulsion comprising high chloride silver halide grains having gold sulfide on the surface of said grain and a bromide rich phase located at the comers, imaging said element utilizing an exposure time of less than 1 microsecond, and developing said element to produce a photographic image.
