PROCESS FOR PREPARING PHOTOGRAPHIC ELEMENTS EXHIBITING DIFFERENTIAL MICRO- AND MACRO-AREA RECORDING CHARACTERISTICS

摘要

- 1 -Abstract of the DisclosureDisclosed herein is a process for forming photo-graphic elements particularly useful in both macro- andmicro-image reproduction. Such an element comprises asupport having thereon one or more silver halide emulsionlayers each primarily responsive to an identical portionof the visible spectrum, at least one of the layers con-taining silver haloiodide grains capable of forming alatent image upon imagewise exposure and a hydrophiliccolloid suspending such grains, and at least one of theemulsion layers also having blended therein silver halidegrains which are surface fogged as though exposed to imag-ing radiation of maximum intensity to render them spon-taneously developable independent of imagewise exposure ofthe element.
