ABSTRACT:
Photographic apparatus usable with a large format film processor for receiving and supporting a cassette holding an exposed film unit and for unlatching structure on the cassette to substantially reduce pressure on the film unit to facilitate its movement over a film bearing surface as the film unit is advanced from the cassette into the entry of the film processor. The cassette includes differently configured forward and rear pressure latch release members and the apparatus includes conforming forward and rear latch release actuators. The actuators are configured to allow the forward release member to pass by the rear actuator without causing premature actuation of the forward release member.
