I've been trying all types if materials for rear projection. and I mean ALL types. I've greased glass sheets and coated them with sugar crystals, lol (on 1 and both sides) I've tried cloths, trashbags, unmbrela material, paper, wax paper, and best of all, wax.

The best method I've found so far is I get a glass pan and put a few pieces of white wax on it. I then put it in the oven on a low heat to melt the wax so it flattens out. (I use just enough wax to make a very thin coating) after the wax cools it gets sort of a fuzy surface. While using this thin wax screen hasn't been a gigantic leap over over materials, I'd say it works best so far and the hotspotting it allmost none. (almost!). However every rear projection material I"ve tried still can't compare with front projection on a white screen. The picture is always washed out, dim, and the contrast is killed. Just looking at it makes you crave the beauty of front projection.

While I thought that rear projection would always be proportionally lower to front projection, no matter how bright or dark it was, last night I made an interesting discovery. (Note I don't have my lumenlab projector yet and I've just been experimenting by holding triplets in front of my 27 inch tv). I cut out some paper bags to close out the light from the tv and cut out a hole to put the lens inside, I turned out almost all the lights then I tried holding white paper in front of the lens, then I tried my wax screen, and I was suprised! In the dark, the rear projection was just slightly darker then the white paper! The objects were not quite as radiant, but not far behind at all. The image didn't appear to be washed out as all like all.

Now I've never used a proffesional rear projection screen but so far I think that I can conclude that rear projection is more sensitive to light then a white screen. So when theres less light, the differance in the quality is decreased greatly.

So, maybe you guys would want to try using rear projection in darker rooms and making sure that absolutely no light hits the screen.

I'd love to see how my wax screen idea looks on a lumenlab projector in a very dark room, though figuring out a way to make a big glass screen covered with wax is going to take some thought, lol.

BTW, joe, Are those new pics in the LLRPTV beta for real??!!!! Those are fantastic!

You know, you could forget all the experiments and just get a RPTV for free and use the material. They are on Craigs list on occasion.

Mikau,

please refrain from making multiple topics in multiple forums about the same things (or even worse, posts in Public Discussion just saying "Check uot my other thread") They're unnecessary and frankly a little annoying...


Thanks!

Sorry

S'okay, no harm done, just don't make a habit of it...

Thanks!
