My friend wanted a Promo-Picture with his Duesenberg 12 string, which I took on Tuesday. Like me, he's not a big fan of overdone skin retouching, especially when it comes to his own pictures, but we agreed that the neck needed a little work in this shot. So I decided to give Pat's method of using the Wavelet Decompose plugin for GIMP for skin retouching, which he demonstrated at the workshop, a try. I was already pretty impressed when I watched the demonstration, but doing this for myself on one of my own pictures made it even more amazing.
Pat has a tutorial on his website, too: http://blog.patdavid.net/2011/12/getting-around-in-gimp-skin-retouching.html
All I can say is, thank you very, very much, because it's gonna make my life as a portrait photographer a lot easier :) And it's just another proof that, as users of open source graphics software, we don't need to hide.
