Abstract: The apparatus includes a projector adapted for illuminating particular things such as art objects. The projector is constructed to receive a mask through which the projected light passes, the mask having an opening or aperture the contour of which conforms exactly to the shape of the object to be illuminated. In one form, the projector is constructed to have a photographic cassette of the self-developing type inserted into it so that a photograph can be made in the projector of the particular object that is to be illuminated. A photographic shutter may be provided with the projector for this purpose. The photograph obtained is superimposed on a sheet of metal masking material and then an aperture is cut in the masking material conforming to the outlines of the photograph of the object to be illuminated.
