3) selective gaussian blur (radius 3 delta 25) to eliminate artifacts around edges
4) greycstoration (-dt 10 -p 0.2 -a 0.6 -alpha 1.0 -sigma 1.0 -fast false) to smoothen the entire image
not bad?

over 15 years agoBy the way, you can apply greyc to just color channels in Photoshop: convert to LAB, apply the filters to the A and B channels, and then convert back to RGB. I think you can do this similarly with the commandline: convert to LAB, save it, and use "-crange 1-2", and then convert it back (but that's a pain).

over 15 years agoMaybe I'll port that to the commandline version. But you use a different version of greyc, and I don't think source code is available for that...
