ABSTRACT:
A data print unit or camera assembly capable of imparting data onto film or similar media disposed within the camera. Preferably, the data print unit includes a lamp chamber having slit limiting projections disposed therein for attenuating reflections created when the lamp is activated in order to produce a cleaner data image overlay on the exposed frame. Also, preferably, this data print unit or camera assembly may include a photosensing lamp triggering circuit in optical communication with the shutter aperture for more accurately timing data lamp activation and duration in response to subject lighting conditions.
