ABSTRACT The preparation of a filter comprises illuminating a photographic material and a mask located at a given distance therefrom with light from the opposite directions to make a hologram and then reproducing an reproduced image of said hologram in the photographic material, thus making it possible to prepare a precise color filter with no need of any close contact of the mask with the photographic material and without causing the mask image to shade off. According to the reproduction of a hologram applicable as a color filter, a master hologram having recorded red, green and blue stripes is located in opposition to a photographic material, and then illuminated with light obtained by mixing the three colors from the photographic material, thus making it possible to reproduce the reproduced image in the photographic material at one exposure operation, while dispensing with a photolithographic step, precise alignment or registration, etc. The process for making a filter photographic material involves laminating together, in opposite relation, a first laminate obtained by laminating a filter layer and an adhesive layer successively on a support and a second laminate obtained by laminating a photoconductive layer and an transparent electrode layer successively on a carrier film through a release layer, followed by removal of the carrier film, thus rendering it possible to prevent the discoloration, fading, etc. of the filter layer and making its preparation more efficient. - 38 -
