projector screen question
in a few onths time i am planning on using a projector to display moving images at a night club. the aim is to hide a stage completely by hanging a massive bit of white fabric over it. the projector is on the ceiling.
can a projector image be projected on to any white fabric?
as the fabric won't be on a wall, but have a big open space behind it, will the image be visable?
will a layer of black fabric behind the white fabric make a difference?
thanks for any advice
