High Contrast lighting against a Green Screen
Posted 16 January 2008 - 08:17 PM
I'm going to be doing some green screen work soon and they want the subjects to be lit pretty contrasty...noirish...
My question for you guys is how bright do I have to get the Green screen to be able to get a decent key off of it while still being able to use contrast on the subject.
These will be full body shots so I have to be able to get a key off the floor also...
Hopefully this makes sense.

The easier approach would be to just have the feet go dark, and have the hard lighting side-y enough that the shadow doesn't fall on the greenscreen floor anywhere near the subject. Remember that you only need a clean green screen around the subject; Shadows and flags that don't touch the subject in frame can be garbage-matted out.

If your floor is the brighter "digital green" you will find that you need surprisingly little light to light it. I highly suggest doing some tests and involving whoever will be doing post to see what you can get away with.

A lot of this seems like common sense after I read it...but I never would have thought about it myself...
Maybe I should lay of the booze and hallucinagenic drugs...or maybe just post more...
