I was given two rolls of very long expired FujiChrome 400 slide film - one of which I gave to a friend, one I kept.
He shot his roll at the rated speed, but did not get much in the way of results. One or two frames had feint images, but the vast majority did not work at all.
The roll expired in 1986, and since it was obtained by the shop who gave it to me, it was refrigerated, however I know nothing of how it was stored before then.
I'm going to give it a try, but I'm not certain the best approach to metering it.
If it was a negative film, I'd just meter it as a much slower film, probably iso 50 or 100, but I've been told that slide film requires much more accurate metering than negative film.
Given how old this film is, is there any way to work out what a more appropriate way to meter it would be?
I'm not particularly worried about getting it wrong, but as it's slightly more expensive to process than negative film, I'd rather increase my chances of getting something back.
