What gels to use for green screen work?
Posted 20 August 2006 - 02:15 PM
of information, including that people like to use green lights for green screen but green Kino
tubes were all that was mentioned. I'm using tungsten lights. Can anybody recommend specific
gels? Also, do people use blue lights for blue screen? Are HMIs good for this sort of thing?
I'm shooting Mini-DV which isn't the best format for green screen because it "loses" too much
color information according to what I've read. Any tips?

Yes, Mini-DV is the worst possible choice for shooting a chroma keyed subject. It has only 1/4 the chroma data since it only samples chroma in one pixel for every square of four luminance pixels. However, contemporary keying software (like Ultimatte Advantage) have some compensatory algorithms to recreate that lost detail.

be sure to use 2 lights coming from the screen as backlight this will help allot with your key.
