I was reading over the article again on projectioncentral about building your own screen for <$100.. again..

here is the link although I imagine most people have read this at one time or another.

http://www.projectorcentral.com/diy_screen.htm

I really need a light gray screen to enhance my blacks for my Acer PH530, but I read this..

Q: Can I use a light gray seamless paper instead of white in order to get better blacks with ambient light?
A: Absolutely not. Light gray seamless paper will give you a ridiculously DULL image. Use white only.

Is this true that you should not use grays? I was going to order some online til I went back to the article and reread it..

I think they are specifically talking about gray paper. It probably is not totally opaque and then if you go gray it will even less efficient. I would be worried about how fragile the paper would be. It might be lots of fun to poke holes in it with little grubby fingers.

I assume you will be putting the screen on a wall. Is that part of the wall smooth and flat?

Well. I am looking at what is called studio gray. here is the rgb as best as I can tell. There is a bit of a red shift, but I should be able to compensate with my projector as it has alot of calibrations. It is a pretty light grey.. like a platinum

G:225
B:225

It is pretty cheap

12 yard roll at $39.. 53" wide.. I am looking for a just under 100" 16:9 so it would give me 2 replacements if it got damaged.

should be very light as well at it will be mostly just 4 1x4 poplars

Can you get a smaller sample? Trying it would be the best idea. What sort of finish does the paper have?

I just picked up a Mitsu HC5500 a couple weeks ago, and my first "dry run" was in my living room which is also home to my wife's photo studio. She had three 9' rolls mounted to the wall. I'm not sure what the specific make and/or color number were, but one was white, another was light gray, and the third was a darker gray. Due to the very low gain of plain paper, anything but the white was nearly unwatchable in anything but totally dark conditions. Even the white wasn't terribly good and passed a lot of the light through the screen as opposed to reflecting it. I'd stay away from this option.

I am a studio photographer by hobby... and I just happened to have White, Black, and Studio Gray backdrop paper in my garage I use for product photography...

After I got an AE700 projector I used a bed sheet and after getting irritated with it (lol i know) I actually made two different test screen using the backdrop paper; while it’s cheap and easy to do... not an ideal material and there was something lacking from the picture quality when you compare to a real screen.

I did learn one thing from my backdrop paper and that was to investigate more into the Gray color. I can tell you from my own experience the Studio Gray color was way too dark in color, a lighter gray would have worked much better. But I did see an advantage of using the gray since the contract was must better over the white paper (my room is very “bright”)

After all this fuss, I ended up buying a manual pull down screen from EliteScreens. For about $110 bucks, I got a nice 92” 16:9 with a matt gray finish and it’s just fantastic.

For the price, and convenience, I was thrilled... not to mention it looked much better than the backdrop paper.

Got iSCSI?
