Nonamer66,

I will eventually but I've got to finish my projector first. I always have more ideas than money. Anyways I was hoping that someone who already has a projector and is already experimenting with screens might try it.

I think a small sheet of maybe 24 inches square would make a nice experiment. Especially if it was put up against an already projected image on say a normal painted wall to see if it offered more contrast and gain in higher light conditions.

Hezz
 
high gain...

IF we uses a material like this...

Reflective tape wont make a good screen. The stuff is designed to return incident light almost exactly to where it came from (within a degree or two). What you end up with is a screen with exceptionally high gain, so you have to have your head right next to the projector lens to see anything.

I use reflective tape made by both 3M and Reflexite in my work, which is how I'm familiar with the way it operates.
