Right, of course.  I was just responding and sorting out the
relationship to the much touted max screen res of 72 (or 100) dpi.   I
think I used to think that meant higher resolutions offerered no
advantages becuase you couldn't see detail below that level, but now I
see it relates mostly to size.  I'm still not entirely sure why high
res scans look better on a screen only capable of displaying 72dpi.  I
tried a slide at 2720 and then 680 dpi, sized the two scans the same,
and the 2720 looked far better, especially under high zooms.
