APUG - View Single Post - Pink or Magenta Cast with T-max, new Tri-X, and other films (not blue or green cast)

Hi,

I just pulled a roll of TMax 100, 120 film out of my jobo. I was using D76 developer. It came out, um, pink - well, heavy magenta perhaps. There are images present, but what should be clear is pink. Sort of like a heavy, dark, Pepto Bismol pink.

All the chemistry is fresh, and I developed some 4x5's two days ago with the same batch, no problem. I don't replenish, all chems are one shot.

This is a newly reconstituted jobo, and I am using some old jugs to hold chemistry. I cleaned them well, and I don't think the solutions are contaminated. They worked for the 4x5 sheets.

Did I short change one of the process steps? Did I not develop long enough? I've never seen this before, and I have developed a lot of TMax in the past and never saw this. However, I don't claim expertise - I've probably just been lucky so far.

Here is my process, basically following Jobo's recommendations: 5 minute rinse, 6:30 in D76, 1:00 stop (ilford stop), 5:00 fix, 5:00 rinse (10 water changes), 1:00 wetting agent bath. Jobo temp set at 20C, motor speed 'P'. (I did preceed my session with a glass of Smoking Loon Cabernet - could *that* be the problem? I didn't pour any down the Jobo! :-)

Help? Thanks!
