Abstract : A process for the production of a phase hologram of tanned gelatin in a gelatin matrix from silver halide photographic material is disclosed. The silver halide photographic material is exposed, developed with a non-tanning developer, bleached with a tanning bleach which removes the metallic silver of the metallic silver image areas while tanning the gelatin in the metallic silver image areas, and is fixed with a non-tanning fixing agent to remove the silver halide from the photographic material.
