In this demonstration the instructor starts off by explaining the very fundamentals of using Photoshop for texturing. From there he goes into depth on how to set up your high res and low res meshes for rendering Normal, AO, and other Maps.

Once the scene and basics have been defined it's on to the entire texturing process of the self contained scene. Everything from the Diffuse, to Spec, Normal, and even a little Emissive and Alpha Maps. The Main textures created are a Concrete Texture set, Wood, Cloth, Grass, Ground, and Metal. This video has almost 5 hours of teaching and demonstration that will serve as the ultimate texturing resource.
