Fomapan 100 at ISO 400, time?

[malias]

Hi, I shot a 135mm roll of Fomapan 100 at ISO 400, I'm going to develop it with HC-110, what do you think is a good time?

Twice the suggested time for EI 100. Expect high contrast negs.

The Massive Dev Chart suggests dilution B for 11.5 minutes. I haven’t tried it myself, and I think it’s a pretty adventurous push—I would expect very high contrast and very little shadow detail, but for some images that could work.

Haven't tried Foma 100 @ 400 but did try Foma 400 @ 1600 in D-76. It worked better than I thought it would.

If your scenes don't have a wide brightness range the film will be more forgiving of push. Also depends on what metering method you are using.

Thank you all very much for your comments. I finally developed it this morning with HC-110 at 20.5ºC (I wasn't very good with the temperature today), so instead of the 11:30 minutes I had planned, I left it for 10:30 minutes. It seems to have turned out well. I let it dry, and in the afternoon I'll probably go down to look at it more closely, cut it, and maybe process some negatives. In any case, I'll upload something so you can see the results. Thanks!

Thanks that will be useful. I may have seen Foma 100 negs pushed to 400 but I cannot recall any so examples are always useful

A promise is a promise. The negatives are as they are; I've just modified the curve to show them as positive:

I'm quite happy with the result, keeping in mind that most of the photos were taken at night... the noise is negligible. I developed with HC-110, 1/31, 20.5ºC for 10:30 minutes (not the 11:30 that massivedev indicated, because the developer was at a temperature of 20.5ºC instead of 20ºC, and I didn't have the patience to wait for it to cool down...)

And since I was busy, I processed some on expired Ilford paper.

Thanks. So these are contact prints or enlarged prints made with an enlarger on expired Ilford darkroom paper?

They are with enlarger

Looks good, all things considered

The negatives are as they are

As expected, most of them are severely underexposed. No amount of additional development will compensate for this. The outdoor shots are better exposed, which may be due to how you metered the scenes.

the developer was at a temperature of 20.5ºC instead of 20ºC

That's not a difference you have to compensate for in practice in B&W development.
