How expired is Acros 100 which it say 03/2015?

baachitraka · Apr 8, 2015

I am thinking to buy some 10 rolls of Acros which has expired on 03/2015. May I know how expired is this film by now or by end of May?

Tom Kershaw · Apr 8, 2015

Um, 03 is March. The film will be fine, it is 100 speed, not Delta 3200.

Dates are far more conservative than they used to be, I'm using HP5 with expriry dates 2008 and 2010 with no issues. Don't give it a second thought.

New HP5 I bought this year is dated 2017 and these short times are more about the ISO 9000 quality standards and stock control than actual useablity and a truer expiry date. How films are stored has more significance.

BEEP... Now it is rendered useless and must immediately be sent to me for official disposal.

baachitraka · Apr 8, 2015

I think I will do that official disposal with my Rolleicord.

Even if it were 03/2005 I would still not worry about it. Acros is super-stable stuff.

Consider that it was probably manufactured 3 or so years ago. Given that with good handling, degradation might start to become measurable (but not necessarily visible) after a decade, do you really think you can tell the difference between 36-month and 37-month old film?

baachitraka · Apr 8, 2015

Expiry of films is always something that I do not understand really well.

Nevertheless, I just bought 10 rolls for €32.00...

It will be awesome. And in several years, probably not much less so...

Marc!

I would not call this expired at all! I´ve bought some 5 packs of Acros with the 03/2015 date too recently for half the price. If the price is right, just buy as much as you need and put it in the fridge. It will be fine for years to come.

Richard S. (rich815) · Apr 8, 2015

Nope. As of midnight 02/28/2015 that film was no longer good! Why take a chance??

(I'm kidding, it's fine). ;-)

I'm finishing up some rolls with a July 2014 expiration date and don't see any problems.

I'm still using LeverKursen APX400 expired 5/2005 which has been stored badly ... bit foggy but still usable.

MattKing · Apr 8, 2015

I'd hate to think what it would say if I was labelled with a "best before" date:confused:

I have some Plus-X 16mm movie film ASA80 from 1978 or so that has a b+f of .38 now.
Seems some other Plus-X 35mm expired 1999 has the same b+f of D.38. I think it would be usable yet if I add 1.3 stops of exposure.
Is a fog level of 0.10 per decade about what others have observed?
This is stored around 65 deg F, not frozen. The accumulated radiation is the main culprit I think. It may be greater if stored in a brick or concrete basement due to the extra radiation mainly from K40 as in my case. I may have added a few years worth of background when I had a 10 uCi Cs137 source nearby for some time before I thought of it.

I store extra ACROS in the freezer and don't worry about it. Frankly, I have never run specific tests on it for overaging like I have with color
film. But with ACROS I probably wouldn't worry if the expiration date said 03/1995. It's not like buying milk.

DREW WILEY · Apr 8, 2015

Er... I should have followed that up with the fact that I recently shot a few sheets of 8x10 ACROS that I bought about twenty years ago, and
it has remained thawed, outside the freezer, the whole time. And it came out Puuuurrrrfect, just like a kitten.

cmacd123 · Apr 8, 2015

I have used Plus-x that was frozen for 20 years, and it was hard to tell from new. as long as it has been kept in reasonable temperatures, (say under 25C) you can probably add a year or two before a critical users would notice any change. and 6 years if you are willing to put up with a bit of base fog and lower speed. (say ISO 80)

Axle · Apr 8, 2015

That's not expired that's Fresh! Heck I've shot Verichrome pan that expired in 1969 and got great results, I shoot Panatomic-X from 79 at ASA-32 and it does great!

Acros 100 that expired less than ten days ago...you'll be just fine, go for it and soup in Xtol.

railwayman3 · Apr 8, 2015

The expiry date is simply the date to which the manufacturer guarantees that the film will, for all normal practical use, give perfect results and correct speed, as it left the factory, and assuming storage in accordance with their recommendations (usually no more than kept dry at reasonable room temperature).
The manufacturer will obviously allow some leeway, and also film deteriorates only very gradually, so, as other posters say, it often has years of good life after the expiry date....it doesn't "go off" on the expiry date.

DREW WILEY · Apr 8, 2015

There seemed to be a misprint on a Pepsi can that came out of the vending machine here the other day. The stamp mark said, Best if used before 1876. But judging from the taste, maybe it wasn't a misprint after all !

Dr Croubie · Apr 8, 2015

Expiry dates on film are exactly the same as expiry dates on food.
They're there to protect the manufacturer, not you.
Use / eat it after the date and you're on your own as far as litigation for failure / food poisoning is concerned.

So where is a manufacturer going to put the date? At the absolute earliest where there's an absolutely minuscule (but non-zero) chance of something going wrong, under the worst realistically-possible storage conditions possible.

But if it's been kept at normal conditions (like anywhere that's not in a car parked in California or Aus), you can easily double most timeframes from manufacture to date and still be fine 999 times in 1000...

(ps, my favourite date is on Cooper's beer bottles. They say 'best after x', because real Ale gets better with age...)

I've just shot & processed a roll of FP4 I bought before moving to Turkeyin 2006, it was loaded in a Pentax MX camera unused for quite a time then removed and stored in a drawer (no container). So not ideal storage but the negatives I made this week are perfect.

Did anyone ever see the really old Mission Impossible tv-series? Remember the tape-recorder that would 'self-destruct' after giving Jim the mission instructions . . ? Well, film isn't like that.
