The last time I shot a green screen with my C300, I was having trouble getting my green screen to actually look green on the screen. It looked more aqua or teal. I tried a few picture profiles. I settled on OFF. I ended up lighting the screen tungsten and the subjects daylight (weird, but it worked). Is this some sort of problem with Canons? Maybe its my particular green screen (sort of a fuzzy latex material)? I have another green screen shoot this week and I'm wondering if I should just bring my EX3 instead, but I want to give the client the better recording quality.
