       I am getting a halo around people when filming them on greenscreens.  I am using full spectrum flourescent lighting.  Both the person and screen are lit well.  When i dim lights down I am still getting the halo.  This has been consitent on various cameras including xl1, vixia hf10, sony hdr-hc1 and sony hdr sr11.  Any help appreciated this is making my life miserable.

       huh?

      lite the screen and subject one at a time.

      bring the person way out in front of the GS...the green you're seeing is often a combo of spill, cheap software, and bad lighting...

      maybe try using one as a back-light

      And how close are you to the green screen?  Industry standard is no closer than 7 feet, while at least 12 is much, much better.  The light bounces off of the screen and lights the subject, giving you a green halo.  The more distance you can put in between yourself and the screen, then better off you will be.

      Also, shirt colors like plum, mauve and magenta kill green.
