I downloaded one of the free sample pictures from
www.3D.sk: source of human photo references for 3D modeling and texturing and applied my healing technique to it. Once I had set up the layers (which took a bit of time to ‘despeckle’ on my old computer), it took less than ten minutes to get the results you can see in the picture above.
It could be a bit better but I wanted to see how quickly I could get some fairly decent results. It’s pretty quick, even if I say so myself!
