Abstract
Abstract A photographic camera for providing a plurality of film images in order to produce a stereogram. The camera has a plurality of objectives which are independently adjustable so that the optical axes of the lenses can be made substantially parallel in a first plane and substantially coplanar in a second plane orthogonal to the first plane. The objectives have substantially the same focal length and common shutter, aperture and focal control. The camera may include a film magazine having a film advance equal to the number of objectives.
