Hi Phil,

I haven't done any zone system dev. for a long time
so it's difficult now for me to think about what is
involved here. It does appear your histogram is a bit
compressed, this means your ISO maybe too high (with
longer development time) for the scene (or maybe I'm
wrong  :(  ).

Anyway, the idea is you want to have the widest
exposure lattitude possible for your film and scene
using your favorite zone system development recipe,
and if the scanner is not able to capture all the
details in one pass, do it twice at different
exposure and merge them in your software.

Ah...perhaps someone else who is currently doing the
same thing as Phil can chime in.

Best,
--nick
