ABSTRACT:
Disclosed herein is a process for forming photographic elements particularly useful in both macro- and micro-image reproduction. Such an element comprises a support having thereon one or more silver halide emulsion layers each primarily responsive to an identical portion of the visible spectrum, at least one of the layers containing silver haloiodide grains capable of forming a latent image upon imagewise exposure and a hydrophilic colloid suspending such grains, and at least one of the emulsion layers also having blended therein silver halide grains which are surface fogged as though exposed to imaging radiation of maximum intensity to render them spontaneously developable independent of imagewise exposure of the element.
