Thanks, Michael, you assured me than my thoughts, while not correct in a math sens, are on their own right way to let me understand how things work and how to get the best profit for my results.
My initial question arised because: 1. After seeing so many times "RGB 48 bits", I had completly forgotten that my scanner has a 32 bits limit. 2. Only a few days ago I felt the need to tune also in the scanning software and not only in Photoshop. I was not understanding quite well the differences between tuning the dynamic range or the white and black points. Now I am getting much closer.
