This may be a bit technical, but I have no experience in the area. I hope someone else has some. I run a small, free theater. I have had four 3D events (anaglyph) over the last 8 years. It's anaglyph because of my screens. I have two matching projectors, and circular polarizers, but I can't use them. I have two true theater screens, a 24' and 28' perforated 'fabric' (some 'screen' plastic) but these two are NOT silvered. Silver fabric screens are a few bucks a square foot at best, the 24x14' screen is 336 square foot. I'm not about to replace it. It's a lace-up, designed to be stretched. I stretch on the X-axis, and only do mild stretch on the Y-axis as I have to roll it up. There is some mild wrinkling that I cannot do anything about (mostly near the edges) and is not visible under normal projection. I was wondering about PAINTING the screen with a reflective coating. Even if the silver paint works, I'm not sure it's a good solution. The problem is that I will still have the mild wrinkling; will that destroy a circular 3D projection? There is a fractional polarization due to angle; each wrinkle is at a slightly different angle to each projector. Has anyone done anything even remotely similar? I was thinking about coating the BACK (non-reflective white) side of the screen so I don't permanently damage my good surface if it fails... but since it is perforated, there may be bleed-through. I also thought about another test where I simply coat a large white tarpaulin with the paint and hang it in front. Also, how do I coat such a big surface evenly? All suggestions are welcome. |
