Actually, I think I'm doing what you suggest. I am using 4x5 continuous
tone negatives. I recently finished building a 4x5 camera partly for this
purpose (OK that was the difficult approach I admit), and the Lith film is
what has been recommended on this list before as a low cost approach to
making enlarged negatives. Developing this film in Dektol 1:10 does
appear to work, and at around $10 for a box of 50 sheets this is
reasonable to play with. I have also tried paper negatives with some
reasonable success.
Basically, I have been pretty much trying to follow what you've written in
your book with some additional input from Sandy King and the list. Always
open to suggestions though.
