Yup, basically avoid wearing green that closely resembles the same colour tone of the greenscreen.

You could use masks on your actors to avoid this issue but that means you'll spend forever and a day masking the actors out of your keyed footage frame by frame. If it's a simple shoot it would be much quicker just to re-shoot without any green clothing.

You may want to adjust some of the peripheral settings on your chroma key/editing software to see if that improves things, as it seems rare to find clothes that are coloured pure green.

What software are you using to key out the green?

As was already mentioned, the most basic rule of greenscreen shooting is:

Don't wear green clothing.

Similarly, if you are shooting bluescreen, you don't wear blue clothing. If you need to have green clothes for the shoot, then you use a different color background for the key. Sometimes you can keep darker shades of green by adjusting the key settings, but since the key functions by identifying any pixels containing green in the image and removing them, its best to avoid it as much as possible.

We may be able to offer more specific suggestions if we can see the image in question and know what software you are using. Also, if you can avoid typing in all caps it would be appreciated, as it looks like you are shouting. Thanks.

Agree with Pooky. ALL CAPS IS ANNOYING and combined with crappy punctuation is even worse. Not mincing words here; everyone gets really annoyed when you do that. I know, because I used to use no caps, though everything else was fine, and I still annoyed people. That's why I switched. Caps is bad. It's a no-no.

The point of chroma key is to key out all green/blue/etc. in the general range of whatever color you chose. Hence, neon green and colors near it in the spectrum will be keyed out. If your actor needs green clothes, use blue screen. And vice versa. If he's wearing both, use a bright lavender.

EDIT: And by the way, post this in the help programs, not general chat. If you have something different, post in the filmmaker's forum.

You can get two screens. One blue and one green. So if one of your clients wears a blue shirt, use the green screen. And if somebody wears a green shirt, use the blue screen. Thats cause the point of keying is to remove all of one color in the frame and keep the other parts of the image.

I'm guessing that this is regarding PhotoKey, so have moved it to the PhotoKey forum.
