[Skids]

I find the skin selection algorithms are not great. I have been working on some images where the person is against a grey background and the colours etc are correct therefore the skin areas are obvious to the human eye but when I select full body I find I have to still paint in a lot of skin areas, in some cases nearly all of it. Then the next picture which is almost identical, skin selection will work fine so I don't understand why the selection areas vary so much.
