This is the result: http://imgur.com/gw38F It's not perfect, but it's fine for the purpose of envisioning what the bike will look like after painting. - I used Select by Color. - I toggled Feather Edges (without it the selection was bad; I removed this fuzziness two steps below). - I played with the Threshold - around 10.0 or 11.0 was fine. - Went to Select / Sharpen to remove fuzziness. - Used Free Select to correct some missing corners - lots of manual work, still not perfect, as you can see, but good enough. - Colors / Hue-Saturation and desaturated it. - Colors / Curves and pulled the curve up from one point in the middle. I guess I shouldn't be so scared of all those options, the program is quite logical after all. :-) -- Florin Andrei http://florin.myip.org/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] changing red area to silver
(I'm a newbie.) I'm trying to modify this image: http://imgur.com/5kHey It's a 2009 Kawasaki ZX-10R. The orange-red areas need to become silver, approximately the color of aluminum. Look at the exhaust pipe - that's pretty close to what I envision. I tried converting it to back/white, but the red area is still too dark. I then tried to play with brightness and contrast, but it looks ugly. Is there a way to select the red parts just based on the fact that they are red? Then somehow get rid of chroma and brighten up just the selected parts? (while preserving shadows, etc.) The goal here is to imagine how the bike will look like once it's painted silver over the red parts. I'm not trying to get anyone do it for me, I'm trying to learn how to do it myself. Any help is appreciated. Thanks. -- Florin Andrei http://florin.myip.org/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
