ABSTRACT:
The air-tight film chamber of a cold camera is maintained moisture free by the action of a chemical dehydrator held in packet form within an auxiliary enclosure attached to the front housing section of the camera within which the film is movably mounted for multiple exposures. A rear housing section detachably assembled to the front section carries the refrigerating means for maintaining the film at a low temperature, inhibiting latent image decay.
