I have been experimenting with TechPan film, and would be interested in
your developer. I am hoping to use this film for copying old
photographs. However, my first attempt using HC110 dilution F gave me
negatives with way too much contrast. I am getting ready to try the TD-3
developer that the Photographers Formulary sells, and will probably give
Kodak's Technidol a try as well. Any words of wisdom for using this film?
