I found a solution. But not by using a filter that directly affects the contrast and brightness :\ The effect I was looking for was to turn green-screen footage of a person into high contrast black&white/grayscale psuedo cartoon footage. Filtering out the green screen was easy, but getting the cartoon-ish effect required fiddling with an inverted 'contrast mask' layer (set to 'grain-extract') and the 'channel-mixer' filter. (and of course the 'cartoon' filter, but that one was easy :) (If you've seen the music video for the Gnarls Barkley song 'Crazy' then you'll probably have an idea of the effect I'm trying to achieve :) Thanks for the help though, Marcel --- Trying to learn about software is like trying to nail Jello to a tree _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
