I was cleaning out a box of stuff that I've been dragging around for years, looking for a old Sekonic light meter, which I found and it works, and in this collection I have some old chemicals. I am pretty sure I picked these up when I worked in a photo lab in the 1970s and they were throwing them out so they may be older than that. What do you think the chances are they still might worth trying? And what kind of film?
If it is direct positive, then there is no use of any redevelopment.
So much about designations applied by the industry themselves, or my standards... Gevaert (and thus later Agfa) had their Dia-Direkt, which was a reversal film too, though the designation not quite that wrong.
