This evening I got a very kind note from one of the organizers of the Third Annual World 3-D Film Expo at the Egyptian Theater in Los Angeles, one of the finest projection facilities for 35mm film left in the United States, in which he wrote,
“I just ran across an article of yours from two years ago, with the title “Real 3D (2011) vs. Natural Vision 3D (1953).” Very good, and very perceptive. Coincidentally, the very film which you mentioned (Dial M for Murder) is going to be shown again at the theater mentioned (the Egyptian) in a few days. The third (and likely final) World 3D Expo is going to take place here at the Expo from September 6 through September 15. It is likely the last one, since Jeff Joseph, the Expo producer is retiring. After that, it is unlikely that it will be possible to see these in their original form any more. 35 different 3D productions will be shown, most of which are from the 1950’s, being shown twin strip 35mm in the original format.
Already some of the 1950’s 3D productions are no longer available on film, so they will be shown in RealD digital, about a half dozen of the 35 screenings, if I recall. The upside is that it will now be possible to make a direct comparison of RealD to 35mm film twinstrip in the same venue. This is probably the only time that 35mm film 3D and digital are being shown on the same screen in the same auditorium at the same event. I remember actually seeing many of these films back in 1952 to 1955.
At that time they were even brighter, because now they are using xenon lamps, but back then they were using lamp houses equipped with the brightest light source ever used to illuminate a screen, white flame carbon arcs with blowers directly on the arc. These produced 16 ft./Lamberts through the polarizers on the screen, for a total of 32 ft./Lamberts with both projectors running. RealD is normally only 3 ft./Lamberts, or 5 in the so-called “bright” version. I don’t know what the output of the xenon lamps are, but I am sure that they will be brighter than the digital, but not anywhere near as bright as the original full blown white flame carbon arcs.”
The amazing schedule includes such films as Hondo, House of Wax, the wildly eccentric thriller The Maze and Miss Sadie Thompson all from 1953, (the peak year for classic 3-D Matural Vision technology) along with many other classics; while it’s too late for me to make it out there, which I regret, especially since this sounds very much like the last hurrah — if you are in the Los Angeles area from September 6 through the 15th, you should really take advantage of the opportunity to view these films in their original format, as they were meant to be shown — double projection 35mm prints in perfect frame-for-frame sync, for an unforgettable viewing experience.
