Expose 10 yo Agfa Scala 200x and Ilford Pan 5 50?

[Erland]

Hello!
One of my kind customers just gave me a brick of Pan F plus 50 and Agfa Scala 200x while fixing their printer. I was told they had it stored in a dark cool compartment for the last 10-15 years, and they hoped I could give it a try.

What should I use as EI? I am going to develop both as regular B&W negative, so I am guessing 100 for the Scala and about 35-40 for the pan f? I know I can try one roll and make decisions afterwards, but just to be in the ballpark the first time.

Any other tips?

Kind regards
Marcus.

If you have several rolls make bracketing tests with one each

I rated expired scala 200-400 and threw it into rodinal 1:100 for an hour.
200 seemed more likely.
10 years should be nothing for a ISO 50 film .. rate it like it's fresh

thanks!
Will try it!

If you develop SCALA as negative, the real speed in Rodinal is probably around EI 80 to begin with, unless you want to develop in some fancy way. I'd rate the first roll at EI 50 and go from there...

I cooked mine at 100 and souped in Rodinal.

I am not using Rodinal unfortunately.. But I will Try my first roll at around 100 then. I really like the contrast you got there BLKRCAT! Very nice indeed.

As already pointed out, Scala is nominally ISO 80-100 when used as a negative film - reversal processing pushes sensitivity as it goes for much higher contrast and density. Pan F has unusually high latent image loss. I don't know whether that also affects shelf life, but there are at least some properties it does not share with the proverbially stable low speed film in general, so beware...

another thing to note is that my shots were on 6x9. I did find though that they did have quite a lot of contrast when I was scanning them. Good luck
