A camera construction including shutter means and holding means adapted to be moved into position for preventing operation of the shutter means each time the shutter moves thereby holding the shutter means against an additional operation until the film in the camera has been advanced to the next frame. The structure of the invention includes means for unlocking the holding means whereby a double exposure of a film frame can be accomplished. The unlocking means comprises a pressure applying arm having spring means normally urging the arm toward the holding means. The arm is retained out of engagement with the holding means until an actuating means positioned on the exterior of the camera housing is operated at which time the unlocking arm is driven against the holding means for displacing the holding means from a holding position with respect to the shutter means.
