Better Textures using Images

I found this youtube tutorial that delved deeper into texturing.  His tips on blending modes of the mix shader, to using the factor in the mix shader, was very helpful and clear.   This is not a beginner level tutorial.  I think beginners should watch this one though.  He has a good work flow for getting realistic Results from his models.   He even talks about some of the mapping choices, which are always good to know to make the images fit onto the meshes better.
