ABSTRACT:
A camera for photographing architectural scale models and the like to obtain photographs having natural full-scale perspective. The camera includes a film back adapted to receive panchromatic, preferably, self-processable type film. From the film back extends a relatively long body which tapers rather sharply from the film back to a narrow pedestal-like base upon which the camera stands and which allows easy access to model features. An optical system resides in the base and includes a long focal length positive lens and pinhole adapted to the long tapered body and an afocal, simple reversed Galilean telescope which serves to establish the camera field of view. Chromatic aberrations which might otherwise cause multiple images due to the long camera optical path are eliminated by appropriate filtering.
