Re: Advice for set decorations to work with lighting and green screen

Ah, another reason to return to 2nd grade spelling: it's "garbage matte", not garbage mat.

As for the statement: [Alan Lloyd] "is just masking out an area that does not get any rendered keying." My understanding, perhaps limited, is that a garbage matte can be used in two ways: to exclude an area from the key, or else to include an area to be keyed. In the latter case, one would fill in the area with matching green/blue, depending on the screen used. On the many green/blue screens I've shot, the director often says, "we'll garbage matte that area" meaning that light stands, flags, whatever that is visible in the frame will later be removed with a garbage matte and replaced with a green that matches the main green. The only time that will not work is when an actor or object crosses in front or behind some "garbage."
