Abstract: A compact viewing frame is described for use by artists to change the size and shape of viewed subject area. The viewing frame includes an opaque frame having a central opening, and an opaque panel which is slidable within the frame to change the size and shape of the opening in the frame. By moving the panel inwardly and outwardly relative to the frame, the artist can easily determine the most desirable composition of the subject to be painted, sketched, etc. It can also be used by photographers or cinematographers.
