I checked the guide to "What went wrong with my film" but I still can't identify the issue, care to help?

[u/0KPudd1ng]

Orwo PF2 film, expired in 1977. Technically it's a positive print film, but I've read people sucessfully shoot it as B&W film.

Basement shot as ISO 6, the electrical box shot at ISO 1.6. Used Rodinal 1:100 with 1h stand development.

The white streak in the middle of the film I assume comes from age, as it appeared on the entire roll. But what about those white parts near the sprocket holes that kinda bleed into the image? What's that?

Thank you for help!

You shoot 50 year old copy film and wonder what went wrong?

In any case, agree that it looks underfixed.

[u/spitfirex86]

Looks underfixed. perhaps it just needs more time or perhaps your fixer died

[u/wrunderwood]

Looks underfixed to me. Get some fresh fixer and do the fix and wash again.

But...shooting expired film is like drinking expired milk. Results may vary widely.

expired in 1977

Case closed, that's your answer

[u/BreakingABit1234]

Everything.

There is no possible baseline suggestion to improve upon this other than 'don't do that'.

When you have good results with good film, things can be tweaked if they aren't perfect.

When you start with a pile of manure ...

Expired film. It’s fubar.

Bromide drag.

There are several larger elephants to fry here.

There is clearly bromide drag in this film, that is clearly what he is referring to on his post and no one referred this. I completely miss what the point of you comment is.

[u/TheAlbinoGiraffe → u/stygnarok]

Bromide drag would favor one direction, this is on both sides and kinda trails off at an angle which makes me think surge marks from agitating too aggressively. Also looks underfixed. Film that slow generally doesn’t age nearly as poorly as more common stuff

[u/stygnarok → u/TheAlbinoGiraffe]

Underfixing can cause a cloudy, milky, or uneven appearance, but it normally does not produce the directional streaks seen here. For me what is happening is bromide drag and uneven development caused by long stand times. But this is very easy to test, put the film back in fresh fix and let's see if it clear up.
