ABSTRACT:
A light lock (10) for a film packet holder (12) provides opposing upper and lower light lock members (32,34) that are urged into contact with opposite exterior surfaces of the film packet 12 after a film packet clip (30) has moved into the holder beyond a point where the light lock (10) defines a closed position. Thus the light lock members (32,34) are only separated by the film packet at the closed position. The light lock members (32,34) are withdrawn from light blocking contact prior to the passage of the clip (30) during film packet removal.
