I'm experimenting with photo texturing. I found one reference photo on the web. I have come to the conclusiion that you need multiple photos at multiple positions: front, side etc. This will make it easier to select and crop areas to give you better blending when applying. This sample is fair but not perfect. I was only able to select two areas for the overall skin. So, I get patchy results.
Thought I would share this observation to new users like myself.
