I think the first film I can remember which was refrigerated was the VPS
for studio use. If it expired w/o refrigeration the color shift was

I have used some ten year old Tri X and it shot ok. At times just a
little contrast fog but nothing worse than Fomapan to was it Formapan
abuot 20 years ago. Ahhh, photoshop can fix anything.
