Green Screen and Green Paint

hello,

just a quick question to anyone who's used Key Green paint. Why do you need to used the $91 paint at the expendible store? Why can't the camera pick up on a green paint from Home Depot?

Stupid question I know, but I know how people love to mark up things saying that their product is the "only way to go"

Has anyone out there tried this and had it work/fail miserably?
 
Ditto. I believe mine was called "Botanica". It's not process green or chroma green. So the preset "Greenscreen" filters won't recognize it in some NLEs. But the Chromakey and Colorkey filters where you use an eyedropper to select the color have no problem with it.
 
I actually made mine the hard way. i printed several "swatches" of green onto white card paper. i hung it on a wall and shot it. took the clip into my NLE and looked to see which square keyed better without me making any major adjustments. i then took the paper to walmart, they scanned it, and i had a gallon of "chromakey" green. :)
 
Actually, that's almost what I did.

I printed a number of green squares on a sheet of white paper, lit it, and then recorded a few seconds in each combination of gamma and matrix setting. Then I tested to see what combination of color and settings keyed the best.

Except instead of having them scan that color, I just held it up against the paint swatches and picked the closest one.
 
Hm, so far reading this forum I got the impression that you just don't do green screen with the DVX but only with cameras with a better chroma/luma ratio.

Am I wrong?
 
Some people seem to get results that please them with the DVX and special software.

I prefer the HVX in DVCPRO50 or in HD mode.
 
Does anybody know the exact paint name of what they got at Walmart or whatever?

I figure if someone already knows what paint will work, telling us would prevent everybody else from having to do more unneeded research.
 
You just need a green that won't get lost in the shadows or highlights easily, and then once you paint an even surface with it, light it evenly and it's all gravy. Neon green isn't really a hard color to recognize at the paint store...
 
You want a more deep green, and a not so much neon green.
The neon will glare and cause spill. You need a deep saturated green.

Here's the EXACT color that you are looking for:

If you are interested in a DIY greenscreen, I discovered that Ritz dyes has an online custom color mixer. You select the color, it tells you how much of which dyes will give it to you. You can also buy raw muslin at the fabric stores pretty cheap if you wanna pretend to be a purist. The true guerilla types will steal the ol' lady's white sheets.
