ABSTRACT:
A method of forming chromogenic photographic image comprising the steps of:
providing an aqueous developable photographic element coated on a single dimensionally stable support, wherein said element comprises in reactive association (1) a developing agent, where said developing agent is a primary amine or a precursor of a primary amine, (2) radiation sensitive silver halide, (3) a color coupler compound that forms or releases a dye upon reaction with the oxidation product of a primary amine developing agent, and (4) a hydrophilic binder;
exposing said element to actinic radiation; and
developing said image by contacting said element with an applied volume of an aqueous processing solution, wherein said applied volume is limited to less than 800% of the swell volume of said element in equilibrium-mechanical contact with said processing solution or the temporal duration of said contacting is limited to a time less than 500% of the time necessary for said element to swell to 90% of said swell volume.
