Abstract (en)
A method of reducing the granularity of an imagewise exposed photographic silver halide colour negative material comprising a support bearing at least one photosensitive silver halide emulsion layer having associated therewith a dye image-forming coupler which method includes processing the imagewise exposed colour negative material to form at least one silver image and corresponding dye image by treatment in a colour developer solution containing a primary amino colour developing agent wherein the colour negative material contains a pyrazolidinone compound of the formula: <CHEM> or a precursor thereof in such amount that the granularity is reduced without any substantial change in dye density at the same level of exposure.
