Abstract
A process of producing a viewable photographic image is disclosed wherein an imagewise exposed photographic element containing at least two silver halide emulsion layers capable of recording within the same region of the spectrum and having differing threshold sensitivities produces during photographic processing spectrally distinguishable images. Separate image records are obtained from the emulsion layers, and the image record corresponding to the photographically superior image is preferentially employed in producing a viewable image.
