bantha, that was my specific thought: the model CAN NOT MOVE. I wonder if the pros on Emily had a camera that could shoot both at the same time.

I'm going to go back and read the Emily information, but in general:

1. what does one need to get a polarized file? A special lens or a special filter or a special setting on the camera?

2. is "taking the difference" a simple thing a person could do in photoshop, and then export spec, normal and bump maps?

{I know many are pursuing procedural bump and spec, but I am still interested in actual maps, for the moment}
