Pushing TMax 100 to 400

[13Promet]

Hello all,

this is my first message in this forum.
I've just come back to film after 10 years of digital (Nikon and Fuji, which I'm still using) and got myself a couple of film Ms (2 & 6) and a few lens.
I'm enjoying a lot this "involution" 🙂

Coming to my question...
Last week, during my holidays in Scotland, I've mistakenly loaded a roll of TMax 100 instead of a 400 (they are so darn similar! :bang🙂.
Therefore, the shots in it are supposed to be underexposed by two and a half stops.
Of course, in that roll I feel are some of the best shots between the 10 rolls i've shot during my whole stay up there (Murphy's law...).
I'd like to save it, if possible. Is it?
Considering that when in doubt I use to overexpose by half a stop, if three stops by chemicals is too much I could push it by two stops only, then try to recover the little underesposure left after digitalizing.

I've had a look at my Ilfosol 3 sheet, but the only EI provided for TMax 100 is 80...

Can anyone suggest me a possible developing process with Ilfosol 3 in order to try to get the best out of this unlucky roll?

Thank you in addvance for any support!

Alessandro

Looking at the Massive Developing Chart, 8.25 minutes in ID-11 works. I know you wanted to use Ilfosol 3, but there is no data for that. My understanding is, Ilfosol 3 is not a real good developer for pushing.

Lots of data in the Massive Developing Chart. I refer to it often when trying new things.

Thanks a lot, bsdunek, I was not aware of the existence of that database: definitely very useful!
I'll get myself a bottle of a developer more suitable for pushing.
TMax Dev should be available at the shop where I usually go, and it seems to be appropriate for the purpose.

funny, I did that last week. I used rodinal 1:25 20c for 8.25 min. VERY high contrast but at least some of the picts could be salvaged with a scanner. I will not be wet printing any of them though
