Green Screen Ratio
 

Hi
I planning to do some green screen shooting with my HD100a.
Can anyone suggest a good light ratio between green screen and subject.
For example should the green screen be one stop brighter than the subject.
Thanks for your help.

Jack,
Lighting ratio's got nothing to do with it. Even lighting on a wrinkle-free background is the answer. I use a couple of softboxes.

Also, avoid light reflecting back on to your subject, rim/backlighting the subject will help with separation. Light your subject and background separtely and you shouldn't go too far wrong.

Hope that helps,

Liam.
