if you're interested, have a photoshop of my original image and see if you can do better (and help me out in the process). my goal was to get rid of the betadine (orange stuff) around that nasty melanoma. wasn't too happy with my result, and i spent all night working on it. it has about 6 layers, some with masks and gradients. used a lot of color dodging and blurring, as well as a pattern fills of skin and median filter. any takers?
