Experiments with ROLLEI T 16-on and old B&W films

#1
Given a LOAD of FILM and the ROLLEIFLEX 'T' by Sons of my Deceased Great Friend. He had not used his FILM for over 30 years -- it is all 1990's and 1980's and some 1976 even ! ! I tested a roll of 1987 dated Kodak Panatomic - X and a 1992 Agfa Pan 100 . I took 3 frames then CUT the film carefully in a changing bag through the 16-on aperture I started at 'Box Speed' and increased exposure by double . The Panatomic -X was still good at 32 ASA ! The Agfa Pan 100 was best at 50 ASA I developed both cut bits in a small Paterson Tank using Rodinal 1+50 for 16 mins @ 20oC as a 'Guess'.
The Panatomic -X needed 17 mins and Agfa Pan 100 needed less -- say 15 mins.

Generally, expired BW film only needs to be over exposed one stop per two decades- except plus x, which I need to do more tests on- but I'd guess that needs one stop per decade.
However, the lower ISO films will need less exposure, but I haven't really had any chance to try any, but I've seen other users around photrio mention technical pannand panatomic x are virtually ageless.
And judging by the quality of your reala upload, your friend took really good care of his films.


Besides... 1976 isn't that old:
I came into possession of a 1946 expired 116 sized Verichrome (not pan). All I need is a camera and Dev tank. That should be interesting.
