Abstract:

A portable, self contained apparatus for exposing and developing photographic film, the apparatus including a camera, a processor unit, and a manually transportable film transfer vehicle. The transfer vehicle is insertable into the camera to receive exposed film into a light impervious chamber therein and into the processor to eject exposed film from the light impervious chamber thereinto. The processor unit utilizes wet processing chemistry and has a plurality of fluidly connected developing and reservoir chambers for developing exposed photographic film and storing the processing chemistry to facilitate transport of the apparatus, respectively, as well as effecting replenishment, heating, and level control of the photographic developing chemistry used in the apparatus.
