Hi there,
I've created some gradient jpg's of realistic skin tones. I use these for my skins and find that they are incredibly realistic. I am including light, dark and mid variants for African, Asian and Caucasian skin in the attached zip file.
I usually photosource my skins using images from 3d.sk, but after that, I bring out the shadows and highlights in the skins by using these gradient files. I just take samples (using the inkdropper tool) of the darker tones for shadows and of lighter tones for highlights.
I hope you find these files useful.
