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.

Abstract: The present invention is directed to a process of forming a photographic element capable of forming a reversal image including a support and two silver halide emulsion layers primarily responsive to a different portion of the visible spectrum upon imagewise exposure of the photographic element. The emulsion layers are positioned to permit iodide ion migration therebetween upon development. Each emulsion layer contains silver halide grains capable of forming a latent image upon imagewise exposure and a hydrophillic colloid suspending the grains. One of the emulsion layers is comprised of silver haloiodide grains. One other of the silver halide emulsion layers additionally contains suspended in the hydrophilic colloid and interspersed with the latent image forming silver halide grains surface fogged silver halide grains which are spontaneously developable independently of imagewise exposure of the photographic element as though exposed to imaging radiation of maximum intensity.
