Question (Tri-X Processing)

[smk]

Hi all,

Does anybody know what is this very strange pattern on the following image?

This is a crop (that shows the pattern), Tri-X developed in DD-X, pushed 1 stop. I've been doing this for years, and I've never encountered anything like this before.

Temperature of development was a bit on the high side (82F), but 4 other rolls developed at the same time do not have this effect. It only appears in 2 out of the 6 rolls I developed today (at the same time).

Thanks,

Savvas

Looks like reticulation from the high dev temperature. Perhaps this was somehow higher for this roll than the others.

Reticulation for sure. Was your rinse water a lot cooler?

Definitely reticulation. Apparently for the rolls have been processed together the development temperature has been uneven from the top to the bottom of the tank. This roll had the bad luck to be at the temperature tolerance margin and developed that effect.
Did you have the development tank submerged in water covering just the lower part of it? That explains the unevenness of the temperature and the effect.

Thank you all for the identification of the problem. This must have happened at the very end, during wash. When I first turned the water on it was very hot. This roll (and the other one exhibiting the same problem) where at the bottom of the tank, hence experienced the very hot water. Very quickly the water temperature was brought to 75F, so I assume this is when this happened.

I've been developing film for almost 3 decades, very consistent with film/developer/process, so I must have always been lucky...I've never made this error before. I learned something today!
