Thanks to all of you guys for replying. I'm actually referring off of Crazy Man Dan's tutorial, and that's a nice effect, Enormator. Problem is, I'm actually referring to extracting a person from a background and as you know, a person isn't one primary color. I can't imagine how a plugin for Alpha-Masking would work....though I know nothing about Alpha-Masking. :? Oh, and I'm really looking forward to the 4.xx releases (nevermind that they're 2 years away) because of the custom brushes. It really is a disadvantage for Paint.NET not to have that feature.
