Digital BW, The Print

I am not at all an expert but I'll kick things of by saying the principle is
similar.  The sensor in a scanner is still a linear device.  But in a
scanner you have a sensor and RAW converter all bundled into one and you
have complete control over the secondary exposure (the exposure of the film
to the scanner sensor).  The film should be exposed for film (obviously) and
then you would certainly want to ensure that you used the full 0-255 range
when scanning.  This is why using the curves and other adjustments at the
scan/RAW stage offer great control.  Once the scanner has made its pass
(so-to-speak) you have to have captured as much of the information on the
film as possible. If you underexposed the film when scanning then you would
have all the same issues as dealing with an underexposed digicam image.
There are others on this forum who have done much more scanning than I who
can likely add a lot more...
