Since I haven't had a Pro PhotoCD scan made of this particular slide
anything I say about shadow or highlight detail would be pure speculation.
I've gotten excellent scans from Pro PhotoCD ("foxtail barley" is a good
example) and the detail in the scan of "Pete" is at least as good as
"barley" but one problem I've had with PhotoCD is bleeding of extreme
highlights into adjacent extreme shadows.  In most of the Pro PhotoCD scans
I've gotten, the circumstances that demonstrate the "bleeding" effect don't
show up or the effect is negligible.
I tried the drum scan with "Pete" because there are lots and lots of bright
highlights adjacent to extreme shadows.  In this scan I didn't see any
"bleeding" at all.  I'm not disappointed.  For the vast majority of my
photos I can't justify the added expense over the Pro PhotoCD scans but for
those that could have problems with "bleeding" and have as much detail as
"Pete" does I'll gladly get another drum scan.
