Diafine as a standard developer?

[BobD]

The latest edition of The Darkroom Cookbook has a formula for "Diafine type" developer in case anyone likes to mix from scratch.

I have not tried this one myself yet.

being new to Diafine , I wondered how long you could you could keep re-using the developer until it was exhausted, by either time or max number of rolls??

Back in the 80s and 90s I'd get 50-70 rolls out of a quart. That usually took me about a year. It doesn't die suddenly. Results will just start looking a bit under developed.

Since my return to darkroom work I've not put nearly that many through the gallon I have, so I've no recent experience. I mixed it in September and it still works fine.
