Abstract
A camera for containing film which captures an image and indication of camera orientations thereon, the camera has a camera housing having a magnet rotatably connected to it for rotating the magnet in response to orientations of the camera housing. A first, second and third sensor are attached to the camera body for sensing a magnetic field from the magnet. An electrical circuit generates a logic table which indicates orientations of the camera housing in response to a signal from the first, second and third sensors. A record head indicates on the film the orientation of the camera derived from the logic table.
