I'm building a photo booth, and instead of the standard front-mounted LCD with a camera above or below the screen, I thought I'd try to design a teleprompter-style booth where the camera is behind a piece of glass angled at 45º with the live view screen mounted horizontally at the base of the glass. Here's a diagram to help illustrate:
The reason for this design is to avoid the off-axis eye problem that's inherent with the standard design...by placing the camera behind the screen, you're virtually guaranteed to have the users looking in the right spot. Anyway, after doing a bunch of research, I determined that I needed beam splitter type glass in order to make this work well...but the actual stuff is relatively expensive at $100 per square foot.
I was eventually pointed to this company, which offers 8"x10" sample glass for $20 each, or a combo pack for $30, so I pulled the trigger on the "Living Room TV Mirror Sample Combo Pack". Assembled everything, turned on the monitor, and discovered I'm getting a double reflection in the glass, as you can see here:
So I can either give the Bathroom Vanity TV Mirror Combo Pack a try for another $30, or I can shell out for the $100 per square foot stuff. I'm inclined to just shell out for the more expensive stuff, as I think this is like buying a tripod..you buy every one on the way up to the expensive one you should have just bought in the first place...lol. An 8x10 sheet of this stuff is $55.55 which isn't horribly expensive, I suppose, for what it purports to do.
Anyway, does anyone have any experience with the beam splitter glass, and more specifically, with this company? Is it everything it promises to be?
Any input is greatly appreciated.
