A method and apparatus for stepwise reproducing a transparent image repetitively onto photosensitive material such as a film, photo printing paper or offset plate, employing a so-called vertical or auto-vertical reproduction camera with a film holder and a model board with a lens between them. A flash light source repetitively projects images onto the light-sensitive material fixedly drawn over the film holder while the image or image component is stepwise moved over the model board along X and Y axes. The lens, film holder and model board positions are fixed, and any change in the reproduction camera remains superfluous since shutter operation is dispensed with and, thus, multiple substantially sharp images are obtained on the photographic material.
