Hi All, I've found some 120 rolls of Provia 400X which expired in 2014 with unknown storage. Any suggestions would be welcome as to what I might expect or a suitable EI would be welcome.
I bought a stock of 400X when it was discontinued, always stored in the freezer apart from a few rolls for immediate use (and even those are usually stored in the fridge.)
I expose at box speed, it gets developed using the regular E6 process. Worked well so far.
well, i would use shoot a test roll and bracket some shots at 400, 320 and 240. but I wold guess that unless its been stored in the sun or hot room, it should be fine at box speed.
