Question for Graham Quince
Hey Graham
You responded to me about a projector setup you did for a school production, you said you got the projectors really close up to the screens, but my question is, if you had them really close to the screens , how did you get the video to show up really big. Because the closer i move my projectors the smaller the video is . Thanks

Before Graham arrives, allow me to stick my nose in: He might have used a wide angle projector lens with a low throw ratio, which equals projection distance divided by projected width. For example to make a 5 foot wide image from 10 feet away, you need a throw ratio of 2. For a 5 foot wide image from 3 feet away, you need a ratio of .6, if they make such a lens.
