Sandy -
Thank you for the helpful remarks. Actually, I think of Kallitype in the same
classification as Van Dyke, but you are right in making the distinction. The
consideration of contrast is one of the primary reasons I am moving to digital
negatives, so hopefully that otherwise frustrating issue will be resolved in
the near future.
Thanks for chiming in.
Cheers -
