Temperature independence?

[stradibarrius]

Here this summer, My tap water is 72f, so I put some ice and water in the sink and set the beaker with the developer in the cold water till the temps comes down to 68f.

I've searched and so far seem to be unable to find a Diafine substitute. Mind you ... I have not had much experience with Diafine and really appreciate its characteristics ... but would love to find an alternative if there is one.

Thanks!

This formula is from Patrick Dignan's book Classic B&W Formulas.

Solution A
Sodium Sulfite, 35 grams - Hydroquinone, 6 grams
Phenidone, 0.2 grams - Sodium Bisulfite, 6 grams
Water to make, 1 liter

Solution B
Sodium Sulfite, 65 grams - Sodium Metaborate, 20 grams
Or, Borax 20 grams, for results "like that of D76"
Water to make, 1 liter

Mr. R. W. Anderson who wrote the article, claims a true
one stop speed boost plus "the advantages ... of
a two bath".

Be advised that when you use a two bath developer that you sacrifice control of film speed and contrast for ease of use.

Thanks everyone for your replies. I'm going to start experimenting with Rodinal again at the higher temperatures. I really like Rodinal - so far. It is interesting that already I can see certain films looking good in some developers while not in others.
One film I do like it Diafine is Fomapan 100.
Actually for the larger 6x7 negative size, the fomapan which I tried on a lark is turning out to be my favorite film. It has a "tooth" for lack of a better word that really works for me, it gives me what I want. I'm starting to wonder why so many film shooters seem to dislike any traces of grain.

So I'm going to shoot some test rolls back to back (nice thing about interchangeable backs) and see how it goes.

Pyro is one of those developers I've long been curious about. Curious but not yet ready. I may have to give it a whirl sooner than I considered. So many choices! Why does life have to be so short!
