just thought about, if anyone of you got a solution for this:

i want to make an installation with a transparent screen which is positioned in the middle of the room. so the screen can be view from both sides. but when i'm projecting through the screen, there are still projections to be seen on the far side of the room.

any idea how i can get rid of that 2nd hand projection? some canvas that swallows the light of the projector or something like that?

thanks for your help

for professional use there is the fabric "molton", used in theatres, photostudios etc. its totally black and absorbes all the light.

you can beam on it 'till your beamer's smoking - NO reflection! ...and fireproof. cover the walls with it - not cheap, though...

more info here:

info in german, but i guess it's ok for you :)

google will help too...

hmm not sure what you mean here - if you are able to see the bright spot of the lens of the projector through the screen then you need a better rear projection screen Dalite fastfolds are the standard gear for this - they will give a good bright image but without seeing the hotspot fromn the projector - other companys such as rosco make screen matireal desinged for rear projection that will not show any hot spots

i did not mean the light-spot of the lense, but the projection on the other side of room (if you project through transparent screens the light goes through the screen on the opposite wall.

and this projection i want not to be seen....

ahh ok, anything thats black and non reflective should do the job - paint or those heavy black thearter style "blackout" cloth drapes

I used to project on Molton for some time because I like black Backgrounds more than whites, so you can see whats there and not what isn't there. Eitherway, You will see a projection on it, too.
Just not that bright. But where should the light go when it has to get through, but no further ??

I'm a newbie.
