Francesco Palombi Posted March 11, 2014 Share Posted March 11, 2014 Hi everyone, I do mostly photography and for an installation I'm planning to project some super 8 videos i'm planning to shoot. My question is, can I project them vertically? I don't have a super 8 projector and I've never used it, so I've no idea if that can be challenging. Thanks, Francesco Link to comment Share on other sites More sharing options...
Jean-Louis Seguin Posted March 12, 2014 Share Posted March 12, 2014 The projector should be kept in the normal position and use a mirror mounted at 45 degrees to project upwards. Jean-Louis Link to comment Share on other sites More sharing options...
Francesco Palombi Posted March 12, 2014 Author Share Posted March 12, 2014 Hi Jean-Louis, my bad. English is not my first language. For vertically I meant "portrait format" oriented video. Does it make sense? Thanks, Francesco Link to comment Share on other sites More sharing options...
Jean-Louis Seguin Posted March 12, 2014 Share Posted March 12, 2014 I suppose you could do it with the projector laying down on its left side. As long as do not block the air circulation to the ventilator grill. Jean-Louis Link to comment Share on other sites More sharing options...
Joerg Polzfusz Posted March 12, 2014 Share Posted March 12, 2014 Does it make sense? Hi! I understand what you want to do. But it doesn't make any sense to me as Super8 is 1:1.33 and hence nearly square. So it wouldn't make any great difference whether you project this way or another...

Andries Molenaar Posted March 12, 2014 Share Posted March 12, 2014 Use two (surface) mirrors, project on one and onto the other, rotate them both a part of total 90 degrees for portrait and of course make them project on the screen ahead. Link to comment Share on other sites More sharing options...

Roberto Pirodda Posted March 14, 2014 Share Posted March 14, 2014 if i have understand correctly what you want to do, you must shoot with your camera rotated by 90 degrees, otherwise you will get vertical horizon-landscape 1 Link to comment Share on other sites More sharing options...
Mark Dunn Posted March 14, 2014 Share Posted March 14, 2014 (edited) Use two (surface) mirrors, project on one and onto the other, rotate them both a part of total 90 degrees for portrait and of course make them project on the screen ahead. You can't rotate a projected image with flat mirrors alone, only reverse it. Edited March 14, 2014 by Mark Dunn Link to comment Share on other sites More sharing options...
Premium Member Dom Jaeger Posted March 14, 2014 Premium Member Share Posted March 14, 2014 You can't rotate a projected image with flat mirrors alone, only reverse it. True, for rotation you need to use something like a Dove prism: http://en.wikipedia.org/wiki/Dove_prism But as Joerg mentioned, the nearly square S8 frame turned sideways is hardly portrait. A fairly simple method to get a more vertical projection aspect ratio is to shoot and then project with a 2X anamorphic lens turned 90 degrees (so that it compresses and later uncompresses vertically). This is what Tacita Dean did for her marvellous Tate installation. A 4:3 horizontal frame would become a 4:6 vertical one, some masking of the sides could make it more portrait still. Or simply mask a normal frame, but you'd lose a lot of image area. For an installation that may be running for a while I don't think turning a projector sideways would be a good idea.

Francesco Palombi Posted March 16, 2014 Author Share Posted March 16, 2014 Thanks everyone. Coming from photography the Super 8 frame turned, for me make kind of a big difference. Just look at 4x5 photography, vertical and horizontal pics. Mmm anyway this sounds tricky..the use of a prism i guess would bring too much attention to the viewer, unless I can kind of hide that. The tape I guess I just have to give it a try and see how it looks. Thanks F Link to comment Share on other sites More sharing options...
Joerg Polzfusz Posted March 17, 2014 Share Posted March 17, 2014 IMHO the main problem would be the heat: Normally the hot gets blown out of the projector to its left side and then floats up: However when the projector gets rotated, the hot air gets blown out to the bottom and then returns: This shouldn't cause a problem when projecting a single reel. However when you do this in an "endless loop" for an installation, I fear that the projector and the film might get too hot. Link to comment Share on other sites More sharing options...
