I came across the following in “The Film Developing Cookbook” by Anchell and Troop (1998):
“Phenidone does not have a long shelf life in dry form. The chemical should not be used for film development if it has been kept for more than six months.”
I was planning on mixing some FX-37, which uses 0.5 g of phenidone per litre, but now I'm having second thoughts. The minimum quantity of phenidone that I can purchase is 10 g. This would yield 20 litres of FX-37 stock solution. At a 1+3 dilution, this means 80 litres of developer, enough for 160 rolls of film. There is no way I can shoot this much film in six months, so I would have to discard most of the phenidone after six months, if Anchell and Troop's assertion is true.
Can anyone confirm or (preferably) refute their assertion?
