Make sure that you have a scanner that will cover that range, I believe
many will, but good to know before you waste hours trying, and do a good
look at your histogram before you hit the scan button. Check you input
and output points to cover a little more than you absolute black and a
touch more than absolute white. Give yourself a chance to use your best
tool to make the adjustments to end points so as not to lose needed
information. If scanning in RGB, even from your B&W negs, you may alter
the USM on the different channels to improve your scans as well.
Silver Fast will give you good control over many functions. They
(Silverfast) also have a program that you can buy that will allow you to
present Photoshop a better file to work on. It is called HD-R or
something like that.
It of course won't let you get details that you lost but can give PS
more to work with.
Practice, Practice, ... with good note taking : )

I have wondered about this. If you processed your negatives for
alt-processes like pt/pd or cyanotype, you probably did make them
denser than negatives for silver gelatin printing. So, how do you
adjust scanner settings to take care of that?
