Use mechanical zoom. You'll LOSE detail with electronic zoom.

If scanning, try different orientations on the platen... you'll get
different lighting directions. A 600dpi scanner like my old MicroTek
Scanmaker E6 won't do small shells... not nearly enough resolution
(solid & reliable, though!). A 2cm shell is too small.
