A rep another forum post that was FROMilford says there is a latent image loss issue with Pan F and it should be developed within 3 months of exposure.
The two "nude" shots I have in my gallery were shot on pan f+ with studio (Profoto) strobes and soft boxes.
The earlier (butt shot) was developed, immediately, the latter shot was developed roughly 3 months later, however I DID keep the rolls in the fridge in between.
In contrast the PXP I shot with at EI 100 were slightly under exposed and I wasn't happy with the flat contrast.
Both developed in Ilfsol 3 in the same time. (Except the first test roll (butt shot).
So hope that's some helpful info.
