Pan F- Develop right after shooting.

[timor]

Nope. It was in my nice relatively cool camera cabinet.

...process PAN F Plus as
soon as possible. Images on exposed but unprocessed film
will not degrade during normal working periods, that is, up to one month when stored as recommended.


Mine certainly sat FAR longer than a month. Maybe 3 to 6. I wish I could find the original article I read on the issue, I'll post it if I come across it.

The info from Ilford is here:

"Once exposed, process PAN F Plus as soon as practical. Images on exposed but unprocessed film will not degrade for up to several months when stored as recommended."
The question is, what Ilford means by saying "not degrade".
