I dunno if this is On topic, but here goes...
A mate of mine is looking for a way of shooting blue screen for a video project he is doing. Does anyone know of any suppliers of cloth/paint etc to use for the bluescreen? (I'm a 'stills' man myself, but I assume the blue screen has to be a certain hue and a matt?, even surface with no secular highlights??)
Here's a useful link:

And I have to say I don't believe this subject is off-topic for digital imaging. When I was working at Unit 5 we used to use bluescreen a lot for shooting stills of lace curtains, windows, props, etc. ready for comping into a preexisting scenes, isolating elements, and adding backgrounds into room-sets. It's much easier to isolate an item if shot onto blue/green if the object being shot is a sub-element of a final shot.
The classic was placing blue behind room-set windows, with lace curtains in front, to create easy masks for external views without having to fret about the lace itself; the consistent colour behind it made it much easier to mask than if the 'window' was simply a hole out into the rest of the studio.
There's a school of thought that says green is better for keying with digital CCDs, because it has less noise (and is compressed less in RGB JPEG files). Bluescreens. however, are better against flesh tones and any 'spill' is less noticeable.
HTH
