Remarques

Marque : "Paramount A Gulf + Western Company Serial MB 0752".

Cet appareil repose sur le système Depic Camera System, développé par Alvin et Mortimer Marks en 1951. En 1982, pour le film Friday the 13th Part III, la Paramount reprend ce système et livre 700 appareils aux cinémas.

"The Paramount 3-D projection system works with a flat lens and produces an image as wide as your normal flat image. However, the height is reduced by approximately 20 %. If your CinemaScope screen width is wider than flat, you can use a smaller focal length lens to fill the screen. Contact Paramount or your theater - or lens-supply company to figure out your exact requirements. Tell them your widest screen width and your throw, and ask them for a flat lens focal length to fill the width of this screen. Do not use any anamorphic (CinemaScope) attachments with this 3-D projection system. If your screen is wider for scope and the height does not change, and you project your flat image in a wide-screen format, then as a general rule you may choose a new focal lenght equal to 80 % of your flat lens. Paramount Pictures Corporation 3-D film can only be projected onto a silver screen. It will not work on any other type of screen. If in doubt about the kind of screen in your theater call Paramount. 3-D film must be framed with the thick black line in the center of the frame. All splices must be made on the thin frame lines. Incorrect framing will distort the 3-D effect. [...] The Paramount 3-D Projection System contains four mirrors and one Polarizer Set, which may be cleaned by the use of canned air. The wider the image you can project on screen, through the use of a lens which fills screen space, the more effective will be the 3-D experience. The lamp house should be operated at maximum safe levels during all operation with 3-D film" (Paramount Pictures Corporation 3-D projection system, Instruction Manual, Paramount, s.d.)
