[Steve Brame] “- Do not overlight the green screen.”
To which I would add, do not underexpose the green screen. Which is a far more common problem.
The VES Handbook of Visual Effects has this to say on the subject:
“A common misconception is that backing brightness should be adjusted to match the level of the foreground illumination. … To reproduce the full range of transparency, the green screen should be fully – but not over – exposed. In other words, its brightness should match the green component of a well-exposed white object like a white shirt, roughly defined a the whitest white in the foreground that still has detail.”
