ABSTRACT:
A method of processing monochrome silver halide material which contains in at least one silver halide layer in addition to the normal image-forming color coupler or couplers a development inhibitor releasing compound which method comprises developing the exposed material in a color developing solution which comprises not more than 2.5 g/liter of a paraphenylene diamine color developing agent which is able to couple with the color coupler or couplers and D.I.R. compound present, the process further comprising silver halide fixing, silver image bleaching and washing steps. The developed photographic images exhibit a remarkable increase in sharpness.
