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.

| Essentially. I couldn't confirm the exact equivelences (my math for
