Camera Back Which Allows Two Discrete Images To Be Sequentially Exposed Onto Single Film Unit
US Patent:
5666579, Sep 9, 1997
Filed:
Apr 26, 1996
Appl. No.:
8/638503
Inventors:
Paul A. Camello - Randolph MA
Assignee:
Polaroid Corporation - Cambridge MA
International Classification:
G03B 142
US Classification:
396323
Abstract:
A camera back for sequentially exposing two spatially separate images on regular or self-developing film adapted for a variety of single lens cameras. The camera back includes an adapter plate disposed between the camera and a film back wherein a dark slide is movable by the force of gravity between two positions in the adapter plate, by rotating the adapter plate 180 degrees, thereby blocking a lower half of the film from the exposing radiation. The dark slide is moved exclusively by its own weight, thereby making complicated levers and light-tight feedthroughs unnecessary.
