definitely not the case here.  unless the preview doesn't show the results
for some reason (it does for positives).  i tried previews with 0, 1, 5,
even 20 for the RGB exposure with no changes in the preview.  i then ran
nikonscan and tried doing previews at -2, 0, and 2.  no change.  i switched
to positive and these huge changes started showing up.
