Hi All,
A few years ago I was given five rolls of Isopan which expired in 1983. As one of the boxes is a bit battered, I thought I'd try it out for fun. The others will stay unused as the retro boxes bring back fond childhood memories.
Anyway, I intend to expose it at 12 ASA but I don't really expect to get very good results from it. I have a question regarding development times, because it's not listed on the Massive Development Chart. I will probably use Rondinax because I like a bit of grain and I would think it was probably the recommended developer at the time the film was made.
I was thinking 1:25 for around 6 minutes?
I generally use a Rondinax 35U tank unless I'm stand developing but stand development would be inappropriate in this instance.
