Feet on greenscreen
on Apr 2, 2012 at 12:02:18 am

In positioning talent for green screen, he is placed as far away from the green screen as possible. But his feet will always contact the green floor as he's standing on it. How do I remove the shadows on the floor created by his legs? How do I prevent spills to his legs created by the green floor? Thanks a lot!

Why would you want to remove the leg shadows? I go out of my way to get them...especially when doing virtual work. What do you think creates the illusion of reality and 3 dimensionality?

Hit the feet area with a softlight to kill the shadows,then mask the area and adjust the keying separate from the rest of the key. but I agree with Dennis, that the real shadows are very useful if you can key them cleanly. Less work than making fake shadows in post later.

Thanks for the advice. How about the spill on the legs, how are they removed? Thank you very much.

Usually your software has a matte choker or something that adds magenta to the green edges... these things are called by different names in every softwaer. You're going to ave to play with settings.

Thanks, Mark! But how about during the shoot, what should I do to prevent spilling on the legs?

Light the floor from a different angle (direction) so as not to have a reflection glare bounce toward the legs.

Wow...you're really fixated on that bounce light on the subjects legs. If you're getting THAT much bounce that your subjet is keying out you're using too much light on the greenscreen -- and from the wrong angle.
You could also try minus green gel in your talent lights and "shinbusters" at the edges of the set.
ALSO...REMEMBER THIS RULE: The angle of incidence = the angle of reflection ......it will be your best friend.

Thanks, Dennis. Does this mean that the floor need not be lighted with the same intensity as the wall? Will this pose a problem during keying in post?

I suspect you're also lighting your upstage wall too bright.
