Secondly, I would recommend using a technique called 'carving'. A good post-processor will know what this is. It's how to make the skin wrap better, and shape the light how you want it. The rule of thumb: Build contrast in post, not in camera.
Anyway, good luck!
Or he could always learn how to use studio flash better so this drastic amount of post processing isn't necessary?
I guess this approach works, if you want to spend countless hours on every file-- which IMO is a huge time suck and workflow killer.
A lot can be done IN CAMERA, and it all has to do with how you light a scene.
The more work you can do in camera, the less you need to do in post.
