Diafine - does it ever die??

[bvy]

Bought and mixed some Diafine in 2014 to process one roll of film that I inadvertently underexposed. Kept it around, and I use it a couple times a year for... whatever. It's not my go to developer or even Plan B. It's just something I use in a pinch, as it's easy, consistent and pretty forgiving when it comes to temperature and keeping. I processed a roll today. Looks great. Here's to the four more years...

Eventually, yes, but more from use than from time. After several years I'll throw it out and mix more just in case.

Diafine wants you to replace once you have diminished Part A by a half as I recall. The stuff is not cheap, but it lasts a long time.

I put aside some working solution and keep the rest as replenisher to top off working solutions as they diminish to attrition. A goes faster than B, obviously, since it's taking dry film and B takes saturated film.
