20 year old ektochrome 64 - shooting/processing tips?

[tomfrh]

I've got some old rolls of ektachrome 64. Should I adjust the speed? What about the processing?

As with any other ancient film, it mostly depends on the storage conditions. If the film has been frozen throughout, I'd go with normal speed and processing and would expect usable results (though don't use it for your daughter's wedding photos....). Otherwise it's a case of trying one test roll and working from the results.

I used a 35mm disposible camera earlier this year, expiry 2005 and found in a desk drawer in a normal warm office, and the results were fine. I've also just had processed an E6 Agfa film (made by Agfa, Leverkusen, therefore pre-2005, but kept in a cool place), again perfect results (and I am very critical !).

I think the first question is "how were they stored"?

The rest will hinge on the answer to that vital question.

The film has been refrigerated (but not frozen) its whole life.

The film has been refrigerated (but not frozen) its whole life.

In that case, I'd try a test film...maybe bracket with a slight extra exposure, but normal processing for a first test.

The biggest reason to try a test film is that it will give you an idea if you need to use colour correcting filters to achieve pleasing colour in projected slides.

Is that an E-4 film?

20yrs ago would still be E6. You could also try cross-processing in C41 for interesting results. I have a box of 50 sheets of EPP I will probably try that at some point soon with that box.
