I don't think ordinary 35mm projectors would operate properly on a vertical plane. The oil wouldn't get to where it's needed, for one thing.  |  IP: Logged Helmut Maripuu Film Handler Posts: 25 From: Västerås Västmanland Sweden Registered: Mar 2004 posted 11-13-2019 04:20 PM                     Century Vista Vision? https://www.youtube.com/watch?v=oBKFQKUYRAk  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

I am not sure how one would mount an anamorphic lens that way on a camera, though. There is probably also a way to do this with prisms. Or is this for projecting stuff that was shot vertically on a cell phone?  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 11-13-2019 06:00 PM                     Well, not quite vertical, but. . . .  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 11-13-2019 06:23 PM                     If you just want to rotate the image by 90 degrees, then you can do that using two mirrors, each at a 45 degree angle. The first redirects the light up or down and the other one to the left or right. You also need to put the projector at a 90 degree angle towards the screen, or you need another mirror. quote: Frank Cox You'll probably need some kind of a mirror arrangement. I don't think ordinary 35mm projectors would operate properly on a vertical plane. The oil wouldn't get to where it's needed, for one thing. It's a bit difficult to do this with 35mm projectors, because they are rather bulky, but it would be entirely doable with some 16mm projectors.  |  IP: Logged Mark Lensenmayer Phenomenal Film Handler Posts: 1605 From: Upper Arlington, OH Registered: Sep 1999 posted 11-13-2019 06:53 PM                     I believe the picture posted by Jim Cassedy is the Jam Handy projector used for the Chevy Show in the '60's.

I used to service these exhibits, but sadly I never took any pictures. The 16mm film was to get around the need for a union operator. The film ran from a loop cabinet.

I had the 1956 film that played on that projector! It was a half dome system. Mark  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 11-14-2019 01:56 PM                        Thinking more about the vertical anamorphic thing: A PL mount lens can be mounted in a camera with a 90-degree rotation, so that should be do-able on both the camera side and the projector side. It would not work with a bayonet-mount lens, but I'm not sure if there is such a thing as a bayonet-mount anamorphic lens. Another possibility would be the 6-perf Cinerama format. If you could find the equipment, a single projector would give a vertical image. I'm not sure how you would shoot this format with anything other than a Cinerama camera with film loaded in only one of the positions, though. Also, this format was never designed for sound-on-film, which might be a problem. I like the dome projector thing. My first thought that it was for a planetariuim show, though I've never seen such a thing done with 35mm film--only with Zeiss star projectors and 35mm slides (or, more recently, "full dome" video projection).  |  IP: Logged Anhtu Vu Film Handler Posts: 98 From: Montreal, Quebec, Canada Registered: Jun 2013 posted 11-14-2019 03:18 PM                     Scott...The image is scope and according to the artist, the installation has been shown before. I just can't seem to find the tech who did it. Do you know how i can adapt a scope lens for vertical projection on the Simplex 35mm ?  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

Then, tighten the screws (but not too much, lest you crack the lens). Most likely, you will need to actually remove the backup lens and attach the anamorphic to a longer one, assuming that you do not have a square screen.  |  IP: Logged Phillip Grace Expert Film Handler Posts: 164 From: ACMI. Melbourne. Australia. Registered: Mar 2004 posted 11-14-2019 06:10 PM                     Anhtu Vu. Hello. Is the artist Tacita Dean? Her production "Film" was exhibited at the Tate Modern in London. In this case, the photographic system is a little unusual. The camera has a Cinemascope aperture and works upright. Only the anamorphic lens is turned 90 degrees which produces a 2x vertical squeeze, (instead of the usual horizontal) on conventional 4-perf film. The resulting prints are on 35mm 4-perf film which runs in a normal upright projector. The image on the film is standard sound width (0.825") and uses the full frame height, (approx 0.715")with a vertical squeeze of 2x. Unsqueezing for projection requires a conventional 2x Anamorphic lens rotated 90 degrees from normal. The projected image aspect ratio can be calculated from the dimensions above, and is something like 1:1.73. The film is projected without sound. If this is to be a gallery installation you also need to consider the running time of the film, and what type of spooling or looping system is available. There is also a French organization "Vertical Cinema" who work with a vertical anamorphic image. In their case they just tip conventional equipment on its side. For projection they use a modified Kinoton E series projector. The mechanism runs quite well laying on its side, but the xenon lamphouse has to remain upright. Projected image aspect ratio is something like 1:2.39 . They tour with their own equipment, and their programs are presented as performances, so conventional film spooling is adequate. The films include a soundtrack. Hope this helps.  |  IP: Logged
