New TMAX400 and Pyrocat
I have a question for Sandy King, or anyone who may know and tested this combination? I've just received a batch of TMY-2 in 120 and I want to test with Pyrocat HD. Sandy gave me good pointers last year for the prior version of TMY in P/Cat, but wanted to know if I could soup the TMY-2 film for the same time?
I currently rate the film at box speed, then pre soak for 3 minutes at 72 Deg F. I then use P/Cat HD in glycol mixed 1:1:100 at 72 deg F and set timer for 16 minutes.
I agitate constantly for 2 minutes, then again for 10 seconds at 12 mins, 8 mins, and 4 mins respectively.
Is this still a good starting point for TMY-2 aswell, or do I need to decrease, or increase my times? The negs are for a dichroic head enlarger, printing mostly on VC and occasionally on graded papers.
Thanks in advance
I have had somewhat mixed results. When I compared the old TMY to TMY-2 with 120 roll film in Pyrocat-HD I got lower contrast with the new film. However, when I compared the old and new T-MAX 400 films in 4X5 sheet film, the results were about the same in terms of contrast. I have slightly more confidence in the sheet film results because it is the film currently being sold and marked TMY-2, whereas the 120 film was an experimental emulsion.

Thanks Sandy, that was quick!!! I'll try it with my standard time, and increase if I need to.

Pre rinse for 3 minutes at 72 Deg f and agitate for minute and let sit for 2.
Pour out rinse water.
Mixed PCat 1:1:100 @ 72 Deg F
Set timer for 16 minutes.
Poured in dev and agitated constantly for 2 minutes.
I then agitated for 10 seconds @ 12 minutes, 8 minutes, and 4 minutes respectively.
stop, rinse, and fix as usual.
So far negs look crisp and fairly close to what I got from the older TMY. Printing them will let me see the difference in performance, but so far so good.
