I have had 8 sheets of 4x5 Fomapan 100 loaded in holders for around a year for my Zero Image pinhole camera. My last batch of film I developed from my Zero Image pinhole camera was back in August 2018, however I did have a year break from photography during this time.
I unfortunately don't use this camera much, even though I have it with me most times I go out, but every time I develop the film from this camera I love the results (most of the time).
May just use it this weekend and leave the RB at home.
These were all developed in Ilford Ilfosol 3 @20 °C for 5 minutes.

This is what happens when you accidentally open your film holder :(
