ABSTRACT OF THE DISCLOSURE A scene containing one or more targets for simulated target practice is photographed in a special motion picture camera such that only one half of each frame is exposed. After reversal development, a transparent template having two sets of aligned, spaced-apart cross-hairs is positioned over the film such that the upper set of cross-hairs is aligned with one of the recorded targets. Then, using the lower pair of cross-hairs as a guide, a pin-hole is punched in the unexposed i.e. opaque portion of the frame. This action is repeated for every frame in the film, altering the size of the dot as need be, as the target moves towards or away from the camera.
