ABSTRACT:
A photographic camera is provided with an orientation detector including first and second elements that move relative to one another under the influence of gravity, and a signal device that responds to magnetic fields between the first and second elements to represent camera orientation. One of the elements is magnetized and the other is a Hall-effect sensor that responds to magnetic fields to produce an electrical output indicative of camera orientation. The signal device includes a recording mechanism responsive to the electrical signal for recording the camera orientation on the film.
