Response to Contrast problem with TechPan
from John O'Connell (oconnell@siam.org)
My Kodak spec sheet says 5-11 minutes at EI 16-25 for Tech Pan. I use
9 minutes at 68 degrees, 1 packet liquid Technidol for each roll
exposed at EI 25. I've only seen flat negs after severe
underexposure, consistent with the underdeveloping theory. You might
try selenuim toning your processed negs -- I've done some toning with
TP and made some negs a little "harder."
