Yes.  Although I'm not sure why Vuescan is delivered with a value of 1 that
doesn't work ?  I always need around 1.4 on slides (using Image setting
which works best for me).

Same on the Canon...including a value of 1 generally working best for
negatives.

The new brightness is better than the old gamma/contrast setting.  Works
better...just set to wrong slide defaults AFAICS.
