Abstract: A unitary frame for mounting a film transparency having leading and trailing ends and spaced parallel sides which surround a picture area. The frame includes first and second members which are adapted for movement between a film transparency loading position and an operative position wherein they enclose and support the transparency. The frame includes, in the transparency loading position, a pair of laterally spaced open-ended guides for slidably receiving the parallel sides of the transparency as it is advanced into its proper relationship relative to the frame, and a pair of surfaces which extend forwardly of the open end of each of the guides and which function to direct the leading end of the transparency into the open end of each of the guides.

Abstract: A compact photographic lighting apparatus for use with a motion picture camera comprising a pair of high intensity lamp-reflector assemblies mounted in side-by-side relation to opposite sides of a central main body support. The main body support is adapted to mate with complementary structure provided on the movie camera with which it is used. Each of the lamp assemblies includes a mounting cone having outwardly extending rib-like structural elements and further including outwardly extending cage-like guard assembly having a lens element at its outermost end. A thumb screw extending vertically through the main body support serves to removably attach the overall assembly to the camera. Electrical connector pins, also received in the camera extend downward rearwardly of the thumb screw and a downwardly extending positioning element, also received in the camera, is positioned forwardly of the thumb screw.
