TMax 400 pushed to 3200 with HC110

I'm very much a baby when it comes to photography - especially film. I was half-way through shooting a roll of TMax 400 for an assignment for class when I realized I had my camera set to 3200. I shot the rest of the roll like that, planning to just go ahead and push.

However, I'm pretty sure that the developer we're using is HC-110 B. Kodak does not recommend HC110 for pushing TMax 400 that far, thus does not give a developing time for it. I don't really have any way to acquire another developer within the next week (last week of the term), so I'm stuck with just HC110.

I've already reshot the assignment, so if I lose the roll, it won't be too big of a deal, but I'd like to go ahead and develop it and see what I come up with.

So, what would be a good target time for developing (our developer is usually at a pretty stable 72°F), and what should I expect using an unrecommended developer?

Oy.

Yeah TMax and big pushes with HC110 will be problematic.

Digital truth looks like it's giving about 30-40% per stop. So unless my math is off, that's about 12 minutes with dilution B at 72.

Developer was a few degrees cooler than normal so I developed it for about 11 minutes. Too much... film looks over-developed. Contact sheet came out really grey, but with some work I can still get good prints. Still much better than I expected considering the circumstances.

Thanks for the help.
🙂

big mistake I made myself for a long while: some devs are made for pushing, others not.
