> Chroma-keying is more tolerant to spill, only needs one camera with one film reel, and you don't need a special screen with special lamps and special cameras. Fair on the number of films/cameras. Is normal keying actually more tolerant to spill or is it just worse so you're going to have to manually deal with spill anyway so you just live with it? I don't even have good eyes and even I sometimes see spill in actual movies, or especially in TV. Edit: I guess that's _different_ spill though. I mean you do famously need a special screen :) And you don't need _special_ lamps per se but you do have to light your greenscreen fairly well to have real success.
