HVX and Geen Screen HELP!!! I really need the Herd on this one.

YOu want the biggest area you can work with, and you want it to mesh with the rest of the 24P footage you are shooting. Shoot 1080p24PA….

Lighting is the absolute key to doing a good greenscreen. The screen should be evenly lit and you want to have good separation between the subject and the greenscreen. Relative exposure between the two elements isn’t too critical – usually within a stop or so of each other – the biggest concern is to control any spill coming from the screen. You should use a backlight on the subject – the quality and intensity based on what will be your background image.

I think you just answered your own question.

If you or your Gaffer have a light meter (Spot meters work best) use that to get a nice flat match to the green behind the person. I wouldn’t shoot without one and my keys are always a breeze to key. Reason being, it’s just one less thing to mess up your key to have it mismatched around the person.

Another trick I use to get a flat exposure on my backing is to shoot the green/blue screen with my camera, open the iris up a few stops until the zebra stripes appear. If the lighting on the backing is uneven, the zebras will show whick areas are under or over oxposed in short order. Simply adjust your lighting until the zebras are as even across the backing as possible. Easy and no light meter required!
