Description: |
| Abstract:
My present invention relates to photography and more particularly to panoramic cameras of the type in which a sensitized strip is fed automatically across the focal plane or across the exposure aperture in timed relation to a sweeping movement of the lens across the subject through the rotation of the camera itself about a properly 20 located center and the invention has for its object the general improvement of a structure of this character with particular reference to the means whereby the view is chosen.
Claim:
In a panoramic camera, the combination with an exposure chamber and automatic film feeding devices, of a diaphragm at the back of the exposure chamber across which the film is fed by the feeding devices, said diaphragm being provided with a focusing screen and with an exposure aperture and adapted to be shifted so that said screen or aperture may be brought, selectively, into the optical axis of the camera. |
