Abstract:

This patent discloses a method for producing a replica image with enhanced contrast from an original photographic image comprising toning the original photographic negative with a stable photofissionable isotope material, placing the toned negative in contract with a replication plate made from a transparent material in which damage tracks left by fission fragments may be made visible by some process such as etching, irradiating the toned negative with high-energy X-rays, and etching the replication plate to render the damage tracks visible and thereby produce the replica image.
