Thanks very much, the example you gave is exactly the kind of thing I would like to do. I guess I know too little about the terminology here; how do I desaturate the image? And what do you mean by color removal? The top layer should have transparent background, shouldn't it? I guess what I'm asking is what did you exactly do when you got your example done? > I should add that the Greycstoration Plug-in will also work wonders in > cartoonifying an image. > > http://www.greyc.ensicaen.fr/~dtschump/greycstoration/index.html I'll take a look at this as well, thanks.
