I kept films with me. Ofcourse there's always security scan, but it should be safe up to iso 1600.
My tmy2 sheets are fine, like fomapan 200, ektar 100 and e100g also. Even velvia 100f quick loads (expired) are fine.
Only those acros quick loads has problems.
I really like quick loads and acros, but this is (or was, as I have developed almost all sheets) a bit alerting.
