I'm about to build up a blue/green screen and I was wondering what color worked the best for DV. I know DV is not the best format for chroma keying so I wonder what are the optimal choices to do.
Generally, a stage paints the cove wall to order - blue, green, black, white. Or you can get a cloth screen to stetch on a frame. The good ones are green on one side and blue on the other.
The bad ones have been walked on by everyone and are now filthy.
The LED rings are not bad. The real cost comes into play with the cost of the
fabric. It depends on how big a set you need. ChromaFlex portable was listed
for $1995. But considering how much extra lighting equipment and electricity
you would need just to properly light a chromokey set..... reasonable.
Keep in mind that since you are post editing you can shoot smaller segments
and composite them together with a matte layer. You can create a blue or green
matte using your graphics editor. Use the eyedropper function from a screen grab
to get the correct color. Please note that with full floor shots the special beads
reflect less light and you need to adjust the keyer setting wider.
I've done a fair bit of chromakeying with DV. As pike mentioned, green is definately best. I used blue in the past - not so hot!
Do some searching and phone calling - there are suppliers that carry green screen fabric - i bought a 6x8 unhemmed sheet of green screen material in Toronto for $100 Canadian. It works beautifully. When I was searching, I saw numerous US suppliers of green screen cloth.
My material is polyester, which does resist wrinkling... but I've found that wrinkles don't seem to matter all that much.... light the drop well enough, pull your subject 15 ft away from it, and light your subject from three directions (left, right, and behind off the shoulder for a bit of "edge") Use umbrellas or softboxes if possible!
Lighting is much more important than color. Blue or green can be keyed fine. Hair can be troublesome if it is fine and feathered as opposed to tighter to the head and thick.
Fast movement can also be a problem with DV chromakey.
Take your time and do a few tests before you get to far into a shoot like this.
I recently bought a green screen from the link below, Belger Photography in Texas. Found them after searching/shopping on the web. 6 ft. x 12 ft, $72, best price I found I think. Haven't had much time to play with it yet.
After a bit of research I think i'll go for Rosco Green paint. It's about 40 $ the Gallon and I can paint lots of things with that. I already have lots of lightning since i'm building the screen for a small television studio.
