life of transparency films?

I have seen some nice transparency (slide) film listed on eBay, but was wondering about what the life expectancy

is of this type of film.

I know negative film, if frozen, is good for years past it's expiration date, and the lower the ASA/ISO the

better. And, if I remember right, B&W film is also good for a long time past expiration. Colder is better,

frozen is best, refrigeration is next, sitting on shelf in home 3rd and sitting in high heat areas is the worst.

 

Thanks!

<p>I would say the life of refrigerated/frozen color film is about the same whether it's negative or transparency. I've used color film that's five years out of date sitting at room temperature in my own house with no problem, at least not beyond what would normally be adjusted for in scanning or printing. But I don't buy expired film because there's no way of knowing whether the seller is telling the truth about storage conditions. It would have to be a pretty good bargain to be worth the risk.</p>

<p>Ive used transparency film 5 years past expiry date unrefrigerated. It worked really well, just a blue cast, easily color corrected in post. </p>

<p>I have a pretty large stock of Fuji Velvia and Provia that I bought from a person I trust who told me he'd kept it frozen. They were a few years past their expiration date when I bought them. And of course I keep it frozen as well. The Provia has a very slight magenta cast that is easily corrected in post. The Velvia is fine.</p>

<p>Actually, I have a rather large stash of expired film I keep frozen -- several different color and B&W emulsions. I'm slowly working through it all, and I'm also doing my own developing these days. So far, I've found most of the color emulsions to be quite close to where I think their colors should be. </p>

 

<p>I have a lot (around 150) medium format slide films 8 years past expiration date. Fuji Provia 100F, Fuji Astia 100, Fuji Velvia 50 (the old version).<br>

They have been stored in normal room temperature (20° C = 68° F), sealed in their original foil. <br>

Because I turned to negative film, I didn't remember them until last week. So I took a Provia 100F, loaded my Plaubel 69w with it, made 8 shots and mailed the film next day to the lab. The results are fantastic.<br>

However, keep in mind to have them developed as soon as you have exposed them. The longer you wait after exposure, the more color cast you will get. 3 years ago I've made the same test, but left the film in the camera for 3 weeks. No chance to filter the purple color cast which looked like purple clouds over all slides.<br>
