I doubt it is really 16 bits...  Do you have a URL that says that the actual
A/D being used is a 16 bit A/D?  If it were, there would be no room for
tonal curve moves.  You always have to provide more space (higher bit depth)
than the actual data, or you can't make tonal adjustments without losing
data.  16 bit data would require a 24 or 32 bit space to work in.

Also, 16 bits is entirely unnecessary to capture image data at, since no
film you will be scanning can have a dynamic range of 4.8!
