Stupid question, perhaps, but considering the film is in the soup and it's something I only have a limited amount of, I should probably ask.

Efke 25, shot at 25, dilute Rodinal, 1+150, 76 degrees (ambient). How long should I leave it in a completely full tank of developer before I take it out? The usual hour, or less?

Rodinal has a thermal coefficient of 2,

A change of 10˚C either doubles or halves the development time.

In an emergency, pretend it is D76 and look at a time temp chart

Interestingly enough, I used 45 minutes and it worked, but not really well.

File size is probably rather large.

I think I'll go a half hour next time.

Oh, and forgive the dust. I haven't quite figured out my scanner's dust problem yet.

I use extreme minimal agitation with Pyrocat PC 1:1:150 and find that my summer temperatures of 80F require much shorter development times - more on the order of 25-30 minutes. I think you would find it similar with Rodinal, although I have done no tests. Try a half hour and you should be able to interpolate.
