Hey all,

My high school TV studio has a green screen, and we have got it to
work, but I get loads of "sparkles" on my subject. Ive looked into
this online, and found that it is cuz of spill from over lighting at
that the screen luminisity or something should be at 40-50
IRE........WHAT IS IRE, and how do i measure that?

thanks
EHSTC
