METHOD FOR PRODUCING A REFLECTED COLORED IMAGE IN A LIGHT-SENSITIVE PANCHROMATIC EMULSION WHICH COMPRISES PASSING A BEAM OF LIGHT THROUGH A BISECTING COMPONENT FOR SPLITTING SAID LIGHT BEAM INTO TWO SEPARATE AND DIVERGENT PATHS OF UNFILTERED LIGHT, REFLECTING SAID LIGHT PATHS IN EACH INSTANCE, PASSING THE REFLECTED LIGHT FROM EACH OF SAID PATHS FROM OPPOSITE DIRECTIONS THROUGH A COMMON FOCAL POINT AND MAINTAINING A TRANSPARENT FILM OF LIGHT-SENSITIVE PANCHROMATIC EMULSION ACROSS SAID FOCAL POINT TO CAUSE STATIONARY RAYS IN SAID LIGHT-SENSITIVE PANCHROMATIC EMULSION PRODUCING AFTER PROPER DEVELOPMENT "ZENKER''S THIN PIECES" IN THE SAID EMULSION.
