Supersensitization of silver halide emulsions is effected by the addition of a metal chelating agent after chemical sensitization or a combination of phenylmercapto- tetrazoles and a metal chelating agent to a spectrally sensitized emulsion. The contrast of the emulsion may also be increased by the addition of this combination of materials after chemical and spectral sensitization.
