Hello, I've been reading various forum posts and articles on chroma keying, but I've gotten a bit stuck on the issue of shadows. I know it's preferable to not have any, but what can you get away with? Below are links to photos of my set, which is a circular room currently painted (badly) white, and lit by 8 fluorescent lights that sit evenly around the top of the circular wall. It's essentially a time-slice / bullet-time setup, with 8 cameras capturing the same action from different viewpoints. I want to paint the whole room with chroma key green to isolate the performer, but I'm worried that the faint shadows cast by the performer will cause me problems. The performer will be wearing a black and white costume.
Now I'm assuming that there is some leeway regarding shadows, judging by some of the things I've seen online, most notably this photo of Keanu Reeves on the Matrix set:
But how much leeway? My cameras are stationary, and the lighting is constant. Any help would be great appreciated! Many thanks, Naren http://www.naren.co.uk
