Ilford FP4 from the '70s

[Boris Mirkov]

I got some Ilford FP4s dated from the 1970s, exposed one as 50 ASA and now I am thinking of the development times. I was thinking maybe some 10ish minutes in stock Microphen (made from powder)?

Dear Boris,

I would think 12 mins in ID11 as a test may be better, but 10mins in Microphen ( if you have no ID11 / D76 ) as a test should be OK.
