Salut Georges,
I have developed film almost 50 years old, so here goes:
Firstly make sure the emulson is not too dry,
very often with old film you can cause cracks in
the emulsion when its too dry. So keep the film
under "normal" conditions for a while, so the
emulsion gets softer and more flexible again.
Secondly overexpose by at least a stop. The film usually slows down a lot.
For the AGFAs I would recommend Rodinal at 1+50
for about 15-20 minutes (at 20 centigrade). Some
people go 1+75 for 30-35 minutes. Don´t agitate too much, every minute.
Be prepared to live with some hefty grain. Old
film goes grainier. The AGFA APX 400 is always
quite grainy anyways (you might get better
results with Rodinal-S, thats the special fine
grain version of Rodinal. I have some if you need it).
Good luck.Feel free to ask me some more.
Love
Snoopy

Hello !
I've been given a bunch of 4x5 sheet film :
Ilford HP4
Agfa AgfaPan 400 expiry date 1974
Agfa AgfaPan 100 Expiry date 1975
All brand new and unopened boxes. Storage life
unknown but as the outer carton seems to have
seen some moisture, it could have been frozen for some time.
Except for the HP4 box which seems to have
suffered from moisture, all films seems fine.
(I've opened one box of each and picked up one
sheet. All the sheets are fine. Well mechanically, at least.
So my question is :
What kind of treatment should I give to these
Old Timer's to get decent results ?
All help appreciated !
