neopan 400@250 iso

[caila77]

I exposed a roll of neopan 400 at 250 ISO but I don't know the time that I can use to develope it. Can someone help me?
I've Rodinal ad Hc-110 but I think that rodinal shouldn't be enough compensative for neopan at this iso value.
thenks in advance for any suggestions
regards

I exposed a roll of neopan 400 at 250 ISO but I don't know the time that I can use to develope it.

I just did 4 rolls of NP400 in a 1 liter tank yesterday. I use the same time as tri-x. Usually I rate both at 200. Develop d76 1:1 for 10.5 minutes. 250 is only 1 stop. I would develop it normally like you usually do.

I really like Neopan 400 in XTOL. I have had very good results exposing it at 250 and developing it in XTOL 1:2 for 12 min. @ 68. This time is just 30 seconds shorter than the recommended time exposed normally at 400 iso.

This is from the Massive Dev Chart. None for HC-110 for Neopan at that rating.
