My favorite colour film has lost two stops

[Kevin Caulfield]

I spent a few days in Tasmania last week at the Freycinet Peninsula and took along some B&W film for my Hasselblad 500 C/M, and also dug out two rolls of Agfa RSX II 50 from the freezer. I expected a one stop extra exposure would be enough to compensate for the age of the RSX II. I collected the processed slide film today, and was surprised to see that one stop over was usually not enough, and I should have allowed about two stops. The film had a 2003 expiry, so it's probably not too surprising. I just thought I should share this if anybody else is shooting old Agfa slide film.

Hi Noel, yes the same batch. The last time I used it was 2005 or 2007, and I rated it at 50.

Hi Kevin
I can stop panic attack,
2007 was not yesterday,
The oldest slide I have is only about 2007 dated need to start again soon then.
Sorry about yours.

No worries, Noel. I just found some other ones I shot in 2009 and they are better. So it has lost a bit in the last five years. But I'm not disappointed. There are no serious colour shifts so I am happy with that.

Hi Kevin

I've looked and most of mine is 2009 exp Fuji 400 so I need to try one soon.

I have lots of 2002 dated Fuji MS 100-800 120 size and find I rate it at 100 ASA still and it comes out well -- it has been in fridge since I was given it many years ago - all that seems to happen is that the D-Max gets lower so you do not get such 'Black Blacks'. ( That is the effect of fog level on slide films)

How was yours stored??

 

[Kevin Caulfield]

It has been in the freezer the whole time.

Hmm that doesn't bode well for my 4x5 Astia100f that's been freezer stored, but expired in 2003...

Agfa slide film was often said not to keep well. I've no experience with it but do have some Optima 100 neg film expired 2007 I believe that seems fine.

I've got some Velvia, Astia, and RSX from about 10 years ago, all allegedly freezered until I got it (but definitely since), and I've never had a major problem with speed-loss. But then again, my metering is hardly an exact science and I add/subtract all sorts of fudge then guess times anyway (especially when an RVP ends up at 1s, I'll just bulb it and count to 3 or 4 in my head for reciprocity).
