Re: 3-D without glasses - VISIDEP and similar systems.

Vision III Imaging Inc. developed a 3-D system described in the SMPTE Journal, Vol.100 No.6, June 1991. I saw a test reel at the time. Only effective while the camera was moving, and then had only a limited effect. It was carefully thought out, but basically, it wasn't impressive enough to be worth the trouble of shooting with the necessary special two-camera rig. The article also includes information on related experiments in the 1980s.

Dead Media fans will be pleased to know that the origins of this system go back much, much further. It was first proposed by an English experimenter Theodore Brown, in 1903 (following experiments and observations dating back to the 1890s). "Brown's Method of Relief Projection" is described by the inventor in THE BOOK OF PHOTOGRAPHY edited by Paul N. Hasluck (Cassell & Co.Ltd,1905).

Brown called his system, variously, Oscillatory Projection, Motional Perspective, and Direct Stereoscopic Projection. He worked on it, with occasional demonstrations, until at least 1930. An attempt was made to market a short film, DANCING, in 1912. (It was advertised in the Kinematograph and Lantern Weekly).

(Now the plug). The full story of Brown and his many '3-D' still and motion picture systems, (including the StereophotoDuplicon, the Stereoscopic Transmitter, the Kinoplastikon) and his many other eccentric inventions (the Spirograph motion picture machine, Red/Green moving picture books),is told in "Theodore Brown's Magic Pictures == the Art and Inventions of a Multi-Media Pioneer" by Stephen Herbert (130 page hardback, 200 illustrations), to be published by The Projection Box, late Nov 1997.
