At least the times I have tried it out it gave me REALLY thin negs and even by extending the times it did not work. Tech-Pan is a strange film and requires different procedures than most other thin emulsion films. The divided D-76 works very well on older, thicker emulsions like the Tri-X, PlusX and even on Neopan 1600, but I suspect there isn't enough absorbtion of the A bath into the film to allow the B bath to activate it in the newer thin- emulsion T-grain films.. I use it as one of my standards for Tri-X, it does compensate nicely for excess contrast and you cant overdevelop the film either. It is also really cheap, you are looking at a 10 cents/roll with it. The A bath last a long time, it is depleted by the 5-7 ml that is soaked into the film, and the Borax is available in your local drugstore as " 20 Mule- team" Borax from Death valley,CA. Even in low value Can$ it is $3,99 for 5 lbs. Thats enough to do about 65 litres of B bath or about 200 rolls! You should try the Tech-Pan, it is a great film. For the first run I would use the Kodak Technidol and establish the film for you and then start playing with other developers. Tom A
