Thanks for the great replies guys.
I will be compositing it later, but it will not be a photoreal. It is to be a video montage / music video. And it will be mostly blacks and whites, desaturated. But despite that I don’t want any color information to be missing, because I’m after a very high quality video. Why would a pure black environment be better? How would I separate my talent from it? Would I use white clothing? What is a difference key and how can I use it?
So I guess my main issue here is, would I be better off
1. Using a shoddy green screen, that gives a bad, rough key. With not a lot of light available.
2. Use a white screen, and get high quality footage, but sacrifice some of the colour information during the key.
Also, Roto scoping is NOT an option. There is no budget or time for that.
Cheers again
