xtol 1:3 and jobo 3010 and density along the edges

[Jordan.K]

I did a batch of tri-x yesterday in xtol 1:3 and a good chunk of the negatives with a lot of smooth sky ended up with less density on the sky edge in the negative. I processed at about 70 degrees for 12 minutes. Aside from the strange edges the negs look pretty good. I've never had that trouble using hc110 for 9 minutes in the jobo 3010. Could that added development time had something to with it? Thanks.

There was probably not enough developer to properly develop because of excessive dilution. Kodak no longer recommends diluting more than 1:1.

I use XTOL replenished in the Jobo 3010 Expert Tank. Following the Jobo and Kodak instructions - Do not pre-wet the film when using XTOL. My experience is to use the full time for rotary processing plus one minute [for replenished XTOL] per Ilford instructions. Reducing the developing by 15% results in under developed negatives.

I always thought the capacities were supposed to be great with xtol? 1:3 for me was 300ml xtol to 900ml distilled water. The 1200ml fits into the drum, so I always go with that amount. My rotation was about 45 rpm.

The rotation rate for 3000 series is "4" per Jobo.

That is about where I set it when using the actual Jobo processor.
