Process for photographic recording of selective areas of an original image, e.g., as equidensities and/or contour images, on a photohardenable material, e.g., (a) nongaseous monomer compound, (b) organic photoinitiator or photoinitiator/sensitizer system and (c) photoinhibitor activatable by ultraviolet radiation, which comprises in either order (A) exposing the photohardenable layer with desensitizing radiation, and (B) photohardening the layer with photohardening radiatiion, exposures (A) and (B) being imagewise exposures with the proviso that if exposure (B) is the first imagewise exposure, a nonimagewise final exposure is utilized.
