ABSTRACT:
A method of producing direct-positive images is provided which comprises developing an exposed direct-positive silver halide emulsion comprising electron-traps and fogged silver halide grains in the absence of halide ions so as to obtain higher maximum density. It is possible to decrease the degree of fogging so as to obtain direct-positive emulsions of high-sensitivity which, when developed in the absence of halide ions, still provide favorable maximum density values.
