Comments: I use Diafine straight as recommended by the manufacturer. Bill is trying different dilutions to reduce the timing precision needed for the B solution. The A solution development time is at least 3 minutes.  When I dump the A solution, I set my gralab to 60 seconds and when the hand hits 45, I pour in the B solution and give five inversions immediately. When the hand hits 0, I dump the B solution and immediately rinse for 10 seconds with water, then immediatly pour in Rapid fix at film strength. The negatives are just brilliant!

Comments: I hate this film.  I've taken some absolutely perfect photographs with it, but I've lost far too many great shots because of its finicky contrast characteristics. The best results I had were in TD-3 at EI 25, though these were contrasty negatives.

Comments: I too don't really like TP. The curve shape is weird, spectral sensitivity is a bit unnatural, it doesn't like any development or exposure variations and it really doesn't like changes in humidity. I think that for the most part limitations in camera and film-flatness precision and improper technique limit its actual image resolution to no better than a traditional-type (non-document) film such as TMX etc.

Comments: Tech Pan has driven me nuts for several months now until I hit upon this PMK-Pyro combination. Now printing is much nicer, although it (TP) still produces some weird (not a surprise now) tonal results. Tech Pan 120 in 450cc SS tank and reel, with a 1/4 inch X 2 inch PVC pipe spacer on the bottom of tank (keeps developer by products away from film). 135 film in 250cc tank.  The TOTAL of Pyro in the developer must be equal for both 120 and 135-36 Tech Pan ( the surface areas being approx equal for both sizes). Presoak for 3 minutes. Agitation at 15 second intervals. 
* With regard to 16mm and Minox negatives, I still use the 250cc tank, but 1A 2B  250 DI water with the 3 min pre-soak and 10 min development, with  agitation at 30 second intervals to produce the best results for these submini negs.
