ABSTRACT:
A template is mounted in the exposure aperture of a film cassette. Indicia situated on the template are recorded on exposed film units which provide a size reference for physical structure pictured in a developed photograph. Photographs taken of the same subject separated by time but having the same template and camera location allow a comparison of the subject to determine physical changes in the time period between photographs. To anchor the template in an operative position a tail projects from one side thereof and wraps around a trailing end wall of the cassette where it is frictionally engaged by the cassette and internal components of the camera.
