ABSTRACT:
A light-tight, elongated, hollow tapered wall base to which a slide housing is movably connected. The slide housing includes a light source which produces a light beam which passes through a filter assembly and a lens assembly to the bottom of the base. A photographic transparency is to be mounted within a slide holder which in turn is movably located in a close fitting relationship within a slide receiving station. The slide receiving station is formed within the slide housing between the filter assembly and the lens assembly. Removably connected to the bottom of the base is a photographic print tray assembly. The photographic print tray assembly includes a focusing target. The image projected from the photographic transparency is to be observed on the focusing target by a view port which is formed within the base. At the desired time, the focusing target is to be removed and the projected image utilized to expose an unexposed photographic print which has previously been incorporated within the photographic print tray assembly.
