A camera for use in a stereophotogrammetric assembly including a pair of camera assemblies, each assembly having a pair of cameras located on either side of a flash lamp assembly. Each of the cameras of the assemblies includes a flat transparent plate located in a camera housing, with the camera lens being adjustable with respect to the plate. A resilient plate-like member associated with an overcenter toggle assembly holds a film length against the glass plate for exposure. Apparatus for providing fiducial marks and a film recordation of the lens adjustment - for stereoplotting purposes - is provided including an internal flash mechanism in the camera housing with light piping extending to the glass plate. Film wastage is minimized by the location of the lens centerpoint (which corresponds to the fiducial marking centerpoint) off the horizontal center of the film length to be exposed. The film is provided for the cameras either by a cassette - which has top and bottom portions spring-clipped together that are detachable when the cassette is inserted into the camera, without any light entering the camera - or by a reel assembly. The reel assembly includes an upper reel housing having a pinch roll arrangement that meters the film frames properly into the camera, and a lower reel housing having an advancing assembly, and a lost motion indexing assembly associated with the film advancing assembly.
