GIMP as I understand it, is an image manipulation program.  If it has spill suppressors, I'm sure you can find out on their website.]]></content>

			<content type="html"><![CDATA[[url=http://www.youtube.com/watch?v=Am8SXn3gxwI]Greenscreen is all over this video.  You can tell which part by the CGI elements[/url]

I used an Office Depot poster board.  It's lightly saturated and not reflective.

Example (note: I adjusted the camera setting so it looks more saturated than it really is)
[img]http://i51.tinypic.com/2d91w8p.png[/img]

And as 0ldscratch and I have been telling you, it's not the only thing you have to do.  Lighting up the set in a way so that the green isn't being reflected off the LEGO pieces is the other thing you have to so, set-wise.

Afterward, in editing and post-production, after you have keyed out the green, you will still have whatever green stuff that's appears on you LEGO piece's reflection (assuming you did what we've suggested).  That's where spill suppression comes in.  It's sort of a color changing tool but its purpose is to get rid of the green edges.

[url=http://fxhome.com/support/tutorials/view/13/Greenscreen+keying]A little google search and you would have found your answer hours ago instead of waiting on us for an answer.[/url]

Here's where I violate the rules.
[img]http://i51.tinypic.com/16h0v9v.png[/img]

Literally right next to the greenscreen, but notice little greenscreen is reflecting off the fig.  The set is picking up most of the green but as you can see in [url=http://www.youtube.com/watch?v=ObmWCo_iUww]this video[/url], it turned out okay.]]></content>

Can you direct me to one of your videos in which you have used a green screen and it is chroma keyed nicely?]]></content>

			<content type="html"><![CDATA[The idea is to have the Lego pick up as little of the greenscreen as possible.  That means putting the greenscreen as far from the set as possible and lighting the set in a way so that the greenscreen is less likely to be reflected.

If it were a different medium (non-reflective materials), it would be a lot easier.]]></content>

Well, they really weren't. Unless you count about eight inches away too close then, no they were not.]]></content>

			<content type="html"><![CDATA[The problem is that your figs are too close to the greenscreen and the figs reflectivity is picking up on it .  Set the greenscreen as far from the set as possible and search for greenscreen lighting online.  Plenty of answers online if you just SEARCH.

Now in terms of post-prod, depending on your software, you would have to use a spill suppression to clean up the rest of the greenscreen element after you've keyed out the green.]]></content>

			<content type="html"><![CDATA[I recently got a green poster board that works really well as a green screen. Although, no matter how hard I try, there is always green on the minifigure. I was wondering... is there any way to reduce that? Like, maybe, a specific color tile or baseplate I could use under it to reduce it or... I don't know. Maybe I am just using the wrong kind of green screen.
