ABSTRACT:
An apparatus for three-dimensional photography provides left and right eye images alternately along the lens axis of a camera for recording alternately on a film strip. The left and right eye images are received along spaced first and second axes separated by a distance substantially consistent with the interocular distance of natural eyes, and are resolved alternately along the lens axis of the camera. Lens assemblies are provided for each eye image to provide a horizontal spread of between 40.degree. and 60.degree. which substantially matches the natural horizontal field of vision. The convergence of the first and second axes is adjustable. The camera may be provided with a viewfinder in which the left and right eye images are separated out again.
