ABSTRACT:
A method of preparing a bleached phase hologram comprising bleaching a silver image of an amplitude hologram formed in a silver halide photographic material with a bleaching solution comprising a liquid medium capable of swelling the gelatin and/or modified gelatin hydrophilic colloid of the silver halide photographic material to an extent of from about 150 to 400% and containing iodine, so as to bleach the silver image by the reaction of the iodine with the silver and the silver image of the amplitude hologram is formed by exposing a silver halide photographic material so as to form a hologram and development and fixing processing the exposed silver halide photographic material.
