In This "Making Of" article I will try to explain the techniques that I used to create this image. I will focus mainly upon the textures/shaders part:
Base Modeling
I reused the geometry of an old nurbs body that I made years ago. Converted to polygons in maya and deleted the faces that were not going to be visible. I took care that almost all polys were 4 sided for a better subdivision later.
Then in ZBrush I adjusted the proportions, its easier using the move and standard brushes.
UV
I create the UVs in maya. This resolution is enough to create the UV's. Making it later with more subdivisions would be more difficult. I decided to create 2 different UV shells/textures for getting more texture resolution. One for only the face, and other for the rest of the head. I tried to place the seams in a hidden part:
Texturing
Once I had finished the Uvs I started creating the texture. I used photographs from the DVD “Essence the face” as the source for the textures of the skin. It comes with hi-res photos of a woman:
