Abstract
A camera having a flash for illuminating an object to be photographed includes a film cassette inside the camera housing. A template is located within the film cassette to overlie a stack of film units during their sequential exposure. The template includes an opaque section with transparent portions to cause an identifying indicia to be produced on any resulting photograph. A reflector is mounted on the camera outside of the field of view of its objective lens and intermediate the flash and the object to be photographed, to reflect a portion of the light from the flash back through the camera lens to impinge on the template. The result, in the developed film unit, is increased contrast in the section of the photograph underlying the template between the opaque and transparent portions.

A kit for use in adapting an instant camera to produce an exposed film unit having indicia imprinted along one end thereof during the exposure of the film unit, the camera including an objective lens having a field of view, a light source having a field of illumination which overlaps the field of view of the objective lens, and a housing for locating a film cassette containing a stack of film units in position for their sequential exposure via an exposure opening in a wall of the film cassette, said kit comprising:
- a template having opaque portions which define indicia adapted to be reproduced on a film unit during its photographic exposure, said template being adapted to be located in superposition with an endmost film unit in this stack of film units in the film cassette;
- and
- a reflector having a reflecting surface and means for mounting said reflector on the camera at a location between the objective lens and a scene to be photographed with said reflecting surface facing toward the objective lens and the light source and being disposed outside of the field of view of the objective lens and within the field of illumination of the light source, whereby during the exposure of the scene a portion of the light from the light source is reflected by said reflecting surface back into the objective lens and then through said indicia and onto the film unit to supplement the scene light passing through the indicia thus recording the indicia on the end of the film unit with an intensity greater than that which would be produced by the reflected scene light alone.
