How to expose expired film

[ericdan]

Hi,
I just ran into a bunch of expired films and I'm wondering how to expose them. All where stored at room temperature.

Neopan Presto 100 expired 2001
Neopan Presto 400 expired 2006

Fujifilm Trebi 100 slide film expired 2003
Velvia expired 2006

One more stop for every 10 years?
Do the black and white films degrade less fast?
Would the slide film be better cross processed at this point?

Shoot one roll of each at box speed and then evaluate the results. If they were not exposed to high temperatures, like in a car, they may be alright.

i can only speak of my personal experience,
expired film is different because no one's film is ever stored the
same way, so it is not easy to give you a straight answer ...

film stored at room temperature, who knows
it depends on the room how constant the temperature was ..
some say the color might be shot ( as in bad, or no good )
the b/w is a crap shoot too, low iso some say lasts longer and degrades less
c41 degrades less than e6 ( some say ) ... i have experience with expired film
my last batch of velvia (and portra ) i shot were 10+years expired and they were
processed normally without any issues ... (i was the original owner when it was
fresh/indate so i know how it was stored, you unfortunately are not so lucky )

i wouldn't photograph anything important with it until you shoot a few rolls to see how
it has held up. some of it ( the b/w ) probably didn't degrade much ( yes 10 years = 1 fstp ) but
the color films might give you trouble ..

(there was a url link here which no longer exists)
join and post the expired film group and let others know of your experiences !

have fun !

Do what Sirius said, you may be surprised.

I have some 8-year-old Polaroid OneFilm (color, probably Agfa). When I tested, I bracketed exposures, taking the same picture at box speed, 1-stop over, and 2-stops over. I decided it was still best at box speed (400). However, there was a color shift from the age, so I tested with an FLD filter (this time at box speed, 1/3 stop, and one full stop); with the FLD it works fine at box speed (the filter effectively slows it down a bit). I found the same to be true of some Konica Centuria Pro 400 I have, needed only an FLD to correct color.

Keep in mind, this is just my experience, and I tested a bit to get here. (Otherwise, it seems the general suggestion is 1 stop for 10 years). I don't use either of these for "important" pictures, but it only took a total of three rolls to get results I'm happy with for general use.

On the other hand, I've found Kodak and Fuji color films to be more robust.

I also had a roll of 10-year-old Tri-X (B&W) and gave it an extra stop of exposure - it was over-exposed. Black and white is quiet resilient.

Thanks a lot. That's right, unfortunately I don't know how they were stored. When I picked them up they were in a glass cabinet that had advertisement posters stuck on the outside. I assume that kept it fairly shady at all times. The room was very dark in general. It was an old man's camera store in Japan. He closed the business a few years back and stuff has just been sitting there.

Please share the results here.

It's probably all fine. Just set your iso dial to whatever's on the box.
