Time difference between Jobo and tank development??

[Eric Rose]

I want to develop some Trix 320 shot at 160asa in a tank using PyroCat-HD. The only times I can find on line are for jobo processing. Any guidance would be appreciated. Preferred dilution is 1:1:100

Can't help directly but does Kodak not give any guidelines for the difference between inversion and constant rotation in its Tri-X literature?

If no-one has any good guidance you could try John Tinsley's approach in his book "Rotary Processing" He claims that by pre-soakiing for 5 mins he was able to stick to the inversion times for a range of Ilford films but admittedly he was using Ilford developers.

I'd have thought that a similar reasoning might apply to Tri-X

Massive Dev. Chart says Pyrocat at 9.5min @ 70 F for 320 sheet film rated at 160asa...might be a good starting point for a baseline test.

If these are pictures you care about you might want to sacrifice sheets to tests before souping the real shots...

The Massive times are for jobo development. The film is 120 mf.

Kodak recommends reducing development times by 15% for rotary processing.

Thanks Rick.

About 15% faster with continuous.

Shoot a test and see how it works. That is the only way to be sure.
