ABSTRACT:
A photographic camera, including a moveable exposure initiation member, is provided with a film brake that is applied by movement of the member to initiate an exposure. The brake engages an element of the film advancing mechanism and thereby arrests film movement during the exposure. The brake is released after the exposure when the member returns to its original position.
A method of assembling a camera also is provided using certain parts reassembled and reused from a single-use camera with a film brake as noted above.
