Question about ambient light in a rear projection setup

post #1 of 4
Thread Starter 
I'm in the process of implementing a rear projection system that is going to serve as a 'background' for a news set for our school. Think of it as a TV studio...

Well, the lighting experts just finished up, and there's a fair amount of light hitting the screen from the front. It's *almost* usable. Almost. The screen now looks somewhat washed out. Actually, I should rephrase that -- I don't think that any light is hitting the screen directly -- It's all ambient. There's just lots of it.

As our budget really won't support a larger projector, I'm evaluating other options for improving this.

One thought is that the projector area behind the screen is not enclosed, and the set lighting is lighting this area almost as much behind the screen as it is in front.

If I totally enclose the projector area, should I see a dramatic improvement i.e. less 'washing out'?

The screen is Da-Lite Da-Tex.

The other option is to add a second projector exactly like the first one, and do some type of image combining. Would that work?

Thanks in advance for any ideas!

Good luck with this! Not to sound like an arse but getting really good info about rear projection is hard. I got the best information when I was thinking about doing a rear setup from the screen manufactures' directly. I contacted 4 home audio/video installers within about 150 range and only one had any experience.

What I can tell you is that the projector will work much better in a dark room. I didnt look at your screens specs but some rear screens are also made for ambient light to hit the viewing side and some arent.

Rear projection set ups pretty much demand total darkness behind the screen.

Rear projection is NOT and option if you have any light at all behind the screen. Don't even go there. If you're budget constrained, rear projection is likely not your best option in any case. None-the-less, in a TV or movie set, your choices are pretty much restricted to rear projection or green screen.
