Hi and still sorry for the translation ...

 

I bought a film Plus X 16 mm dated 40 years (50 asa) and I wanted to know how much of asa should I expose it. If you can give me your opinion. Thank you...

Unless it was stored frozen, you won't get much of an image out of it. Anything much over 30 years old, is going to be stuck together and have emulsion issues, even if stored properly.

So the ISO you shoot it at, is probably almost irrelevant.

I have some 16mm Ilford FP3 from way back, probably 1960ish ! And it still produces a reasonable image, and steady, but with general foggy appearance... I rate it about a stop slower.

Use it for an art film maybe, but don't expect too much.

If it's in a taped can, anything that would stick the film together , such as damp, would probably have affected the packaging too. Anyway you can check that in the dark, just pull off a couple of feet.

The problem is that exposure is somewhat critical for reversal, so I'd probably develop it as neg. I don't know if that in itself causes any loss of speed.

I thank you I will listen to your advice and I have a friend who used the same film and advised me to expose it to 25 ASA.

I do a very short bracket test, firing tiny bursts with a covered lens in between, then develop on Jobo 110 reel.

Proper exposure depends on details in dark and light areas. Expose for shadows, develop for highlights.
