Thanks in advance.

For exposure, you generally want the green screen to read (reflected) one stop under.

The issue is that most good greenscreen paints have (or at least claim to have) considerably more dye or pigment in them than conventional paints, to produce better saturation. I'm not really sure how necessary this is, though.

That being said, I'm sure the proper green screen paints have something a bit different about them which certainly can't hurt in keying.

The guy at the local Lowes swears his computer will match proper green screen paint. Would someone mind sending me a sample from their set or from a can of their paint in an envelope by US Mail? About 1 inch square or so will do. PM me and I'll throw you my mailing address.
Thanks in advance.
you can purchase this paint or just pick a highly saturated green that is flat. If not muralo or rosco, but rather lowes brand, apply three thin coats.

I think I recall something about the pigment formula in green screen paint was tuned to a light frequency hole in Kodak's negative stock. Or was it that it was tuned to fit kinoflos? From what you're saying, David, it sounds like it doesn't matter to a computer. Is that what it is?
Yes. Now being (professional) I purchased 12x12 and 6x6 Green Screens but if I did not have them I would not hesitate to just pick a flat green from the paint store. Taking some paint chips (samples) to your closest rental house will give you your answer as to which would closest (match). I know a guy who covered a wall with green construction paper... worked great.

If they were green, then you might have a problem keying out just the green screen without losing part of your aliens. In that case, you'd want to opt for another color screen.
What if I cast any aliens. Won't they come off invisible?
The only reason that green is the predominate color used for chromakey screens is that it is the complementary color (opposite side of a color wheel) of "average" caucasian skintone and will therefore have the least chance of keying out part of your talent's face. If your talent were to have a different skin color (like green aliens) or you wanted to have some element of the foreground be green, it would be to your benefit to use a different color for your chromakey screen. In the case of green aliens, an orange-red screen would work best.
But everyone knows green aliens are a myth. Real aliens are gray. Or 3-foot tall walking teddy-bears.

Joking aside, I am putting a couple of CGI Grays in this production as brief cut-aways.
