the hi bit output from Silverfast is not gamma corrected. All the
information is there but to correct it in photoshop you need to do a levels
command to set b/w points (use auto with 0% clipping) and then  change the
gamma either using the centre slider in levels or by applying levels and
going into curves and fiddling with the midtones.

As someone else said it is possible to output gamma corrected 16-bit files
from Silverfast. You set this in options somewhere... with a check
box...would look it up for you but disk crash has taken out all my apps this
week.
