ABSTRACT:
A device for producing photographic exposures of images appearing on an image screen onto a film platform carrying a plane film comprises a support holding a number of objectives and displaceable parallel to the axis extending through the central point of the image screen and the central point of the film platform. The platform carries one objective fixed to the platform of one magnifying property and four additional objectives which have such magnifying properties that each of them projects the picture field area of the screen on only one fourth of the usable film surface.
