Outdated film advice

[Stephen L]

Rooting in the salad drawer of the fridge yesterday (first time I’ve been in that place) I came across some films my wife had put there because she thought it was “a good idea”. (Didn’t have the heart to tell her it was)
Anyway , two of the films were rolls of Velvia 100 ASA on 120, so I think I’ll put them through the Selfix. The question is, their expiry date was 2012, so do I need to adjust the speed rating? I will be having them processed commercially.

General accepted wisdom is that you should add a stop for every decade.

My advice would be, expect to get nothing then if you do get something acceptable you're a winner and don't shoot anything important.

There are Velvia fans on here such as @Woodsy who might be able to help, but I always found it a pest for exposure. I recall suggestions of iso 40 for the Velvia 50, but don't recall similar advice for the 100. I think there were actually 2 versions of Velvia 100 as well, but could be wrong about that one.

Thinking about it, I recall using a film from that batch around 2015 in my Bronica at the rated speed with success.

Slide is always a bit tricky because the latitude is so narrow, you can afford to over expose neg film but slide is less forgiving.
I count in its favour the fact that the lower the native sensitivity of the film, the less effect degradation has over time.
Course, that depends on how its been stored but if I had an 8 year old roll of 100 slide stored in the fridge all its life, I would probably still shoot it at box.
If storage is unknown, then I'd take Nicks advice or chance it with a half stop...

I've shot loads of ood velvia 100F at box, a lot with unknown storage methods and I've had very few failures that I can definitely blame the film for

I’m pretty sure it’s been in the salad drawer since it was bought, over 3 house moves. As I said, I try to avoid the salad drawer.

I suppose if you've shot slide, especially Velvia 50 and 100 before, you're well acquainted with the exposure latitude and hence how to meter for it effectively?

If so, given that it's been kept cold, I'd be confident suggesting that box speed would be fine. If in doubt though, add 1/3 stop, or perhaps 1/2 stop if the dynamic range of the scene allows. I've definitely shot velvia 50 that's on the order of 5-6 years OOD with unknown storage and it's been fine. I've got some OOD velvia 50 in the freezer which went off in 2014, but as it's been frozen, I'll be shooting it at box speed with no correction.
