Efke 25 3-Stop Push in Rodinal

[Pioneer]

I made a bit of a mistake yesterday when I mixed in a couple of sheets of Efke PL25 with some HP5+ I was working with. Needless to say I exposed two sheets of Efke 25 as though it were HP5+. Fortunately I was exposing the HP5+ at an EI of about 160 instead of my normal 250 or 320 for other reasons.

So...I will obviously need to push the development of this film by at least 3 stops. Since I like how Rodinal and Efke 25 work together I am thinking of going with a 60 or 90 minute stand in Rodinal.

What is the general consensus of the group? Good idea or are there better options for this?

Well, it seems to have worked out OK.

Efke 25 accidentally underexposed at EI160. Souped in Rodinal 1+60 for 80 minutes at about 72 Fahrenheit. Agitated for a minute and then just left it to sit. I checked the temperature in the tray a couple of times and it slowly dropped to a little over 70F during the time the negatives sat in the developer. The SP810 tray is covered and seems to hold temperature pretty well.

Negatives are certainly usable but may be a bit contrasty. It doesn't seem too bad though. I'll have to wait and see how they print.

Would love to see the results!

I'll try to get something up. It may have to be a raw scan if I can't find time to get into the darkroom.

Well, I'm two days late and you've already done it, but what I was going to say was:
Efke 25 is pretty contrasty film and pushing it really hard will make it contrastier* still. Since stand developing is compensating and doesn't really care what EI you exposed at, it seems like it would be a perfect choice.
Since you've already done it and it worked I can pretend to have been really prescient.

*Is contrastier a word? I don't see why it shouldn't be. I'm declaring it a word.
