Abstract
The invention relates to a microphotographic apparatus which superimposes one set of film format markings on an image recorded by a film type held by a camera attachment. Specifically, the apparatus has two opaque carriers with multiple sets of transparent markings. These carriers can be moved relative to one another such that only one set of markings on the first carrier is aligned with a corresponding set of markings on the second carrier and therefore, when light is projected through the carriers only one set of markings is superimposed on the recorded image.
