THE CINE-TECHNICIAN
October, 1953
In the same issue of " American Cinematographer " Herbert Lightman has an article on Vistarama, another wide-screen system employing an anamorphoscope ' squeeze ' lens which can be fitted to standard 35mm. or 16mm. cameras. The system is essentially the same as 20th Century Fox's Cinemascope except that the one lens may be used for both taking and projection. The aspect ratio of the projected picture is 2.66 to 1.
The fact that Vistarama will be available to makers of educational and industrial films on 16mm. stock is an interesting aspect of this latest entrant in the wide-screen field.
Vistarama is based on the anamorphoscope principles set down by Henri Chretien. However, the actual lenses were formulated and ground by the Simpson Optical Co., of Chicago, to the order of Carl Dudley, of the Vistarama Corporation in Hollywood.
BOTH in the U.S.A. and here 3-D on single film has been developed. In this country Lesley Dudley, a pioneer worker in the field of stereoscopy, has in use a system whereby a stereo pair is photographed on to a single frame side by side by means of an attachment employing a train of prisms. A
similar attachment must of course be used when projecting the picture.
In the U.S.A. a system known as the Morroptican, developed by Boris Morros in Vienna, is announced as being on the verge of commercial development. It sounds in principle similar to Dudley's system. In addition it is claimed that pictures shot for 3-D by the existing two-camera system can be optically printed on to one strip of film. The advantage claimed for this method is that the projector attachment is comparatively cheap; the disadvantage is that the loss of light in projection is rather greater. Another promising possibility, which has reached an advanced stage of development, is the Vectograph film, a product of the Polaroid Company. The film itself carries the polarising elements in its structure. The film has two sides on a clear base. The images on the two sides of the film are polarised at 90° to each other. Through the polarising viewers the left eye sees the image on one surface of the Vectograph film, and the right eye the image on the other side. This system does away with polarising filters on the projector, and the need to use two projectors.
