Don’t expect any of the paint, cheap copy or expensive original, to work right unless you first lay down a good flat white primer. It will make or break the resulting chromakey color and texture.

[Chris Bové]

Remember that the whole purpose of a chroma key is to be able to select that color and only that color. Mark’s right on the white primer. Also, make sure there is as little texture as possible. Also, no gloss! Reflections, no matter how dull, are translated by edit systems as a different color than what you pick.

Also, the biggest problem with chroma keys is having the subject too close to the color (thus it reflects onto their clothing, etc – like a weatherman). Build depth into your shot.

i hear the rule of thumb for distance is 8 ft…i guess i’ll see. I’ll post some .mov’s when we get it up and running with the camera system.

i phoned some company in california (i’m in philly) and asked them, they said that there is some brand ( i didn’t write it down ) that has accompanying software for batching out of photoshop, or keying in ae, which is and is supposed to look AMAZING, but the company i’m with is frugal. i think it was 45 bucks a gallon for this stuff, but we went with REPTAR GREEN. hhahahahah

i really appreciate all of your help.

When depth is not an option, use a backlight most opposite the key color thus with green screen a light blue backlight will help counter the green contamination. Amber works well with blue screen.

Man, that’s a damn cool idea. One of those “sheesh, yeah, duh?” moments. Good one, CK.

Actually, i believe if you examine a color wheel, what you want to use to kill spill for gelling the backlight on green screen is magenta, not blue. Blue is right next to green, contaminates the key.

On greenscreen, it’s a “magenta” gel, on blue screen, “bastard amber” gel.

as you were… ‘;-)

Yep, I thought about that after I went to bed, and visualized a vectorscope in my head. I intended to correct the statement but you beat me to it, thank you for noticing.

See, here’s why Charlie is more successful in the business than me and is a moderator here: where I try to visualize Heather Graham in my sleep, he’s visualizing vectorscopes.

ONE of us has screwed-up priorities;-)

Actually, I visualize many female stars, and the vectorscope traces showing the colors they are wearing.
