Abstract
A camera for use with a photographic element having a plurality of the exposure frames each having a registration perforation arranged in a predetermined relationship one with each frame. The camera is provided with an improved registration or metering means which includes a fixed element extending into the film plane and disposed in the camera adjacent the exposure aperture in a similar predetermined relationship therewith as the registration perforations are to the exposure frames of the photographic element or film. A movable element adjacent the fixed element is arranged to engage the photographic element to move the photographic element out of the predetermined plane to disengage the registration perforation from the fixed element whereby the film moving means of the camera can move the next frame of the film to the exposure aperture where it is engaged at least by the fixed element.
