        Yes, Nikonscan works this way.  During its prescan, the best exposure
is determined ... however & although you have no idea what it came up
with in terms of a hard value, you are able to make manual adjustments
via "analog gain", which because Nikonscan is intimate with the
scanner, can make these adjustments with intuitive and relative EI
increments.
        I believe, because Vuescan primarily caters to film scanners, Ed can
assume a photographer is using it.  Leastwise, if he does decide to
make adjustments "intuitive", he makes them intuitive for
"photographers".
