I don't use Silverfast but my guess is that the "HDR" mode scans the
negative at least twice - once normal, and then once way overexposed to get
the shadow details, and then it merges them. Digital HDR normally does +EV,
normal, -EV and merge 3, but I think with B&W neg you can make do with 2
exposures....
