A method of processing an imagewise exposed color photographic film, said film having at least three light-sensitive units which have their individual sensitivities in different wavelength regions, each of the units comprising at least one light sensitive silver halide emulsion and image dye coupler, which method comprises contacting the imagewise exposed color photographic film with an aqueous solution containing a non-blocked developing agent, at a temperature of between 30 to 60° C.; and wherein said film further comprises an incorporated reducing agent, at least one organic silver salt and an amido compound wherein the reducing agent is substantially unreactive in the aqueous color development step described above, but wherein color development of the same imagewise exposed film is capable of being alternatively obtained, without any externally applied developing agent, by heating said film to a temperature above about 80° C. essentially in the absence of aqueous solutions, such that the incorporated reducing agent reacts to form dye by reacting with the image dye couplers; with the proviso that the amido compound effectively reduces contrast when the film is heated above 80° C. but does not substantially reduce contrast when the film is processed by contacting the imagewise exposed color photographic film with a non-blocked developing agent under aqueous conditions, at a temperature of between 30 to 60° C.
An article of manufacture comprising a packaged color photographic film which photographic film has at least three light-sensitive units which have their individual sensitivities in different wavelength regions, each of the units comprising at least one light-sensitive silver halide emulsion layer, an image dye coupler, and a blocked phenylenediamine developing agent, wherein the film is enclosed by a package on which indicia indicates that the film may be processed by either a wet-chemical process or a thermal processing method;
