Hi,
yesterday I tried Fuji ACROS in the daylight, since I had really great negs from it at night. The results were mediocre.
The camera I used, was a Yashica-12 with 120 Film.
I have two questions:
1. I have vertical streaks on the negative (see attachment). Could that be under-fixing? The fixer might have been exhausted.
2. I processed a second roll in the same solutions afterwards (Ilford HP5+). At the end, I found quite a lot of "goo" looking like clear gelatine. I thought that the film emulsion might have gone off but the negs don't have any damage that confirms that. It might have been an expired film.
Did you ever notice something like that?!
Kind Regards

It might help others reading about your problem if you posted what type of camera and age of it. I have seen foam in the back door go very gummy, and leave it on the film while advancing.

Thanks for the tip, I added the info above so everybody finds it (Yashica-12, around 60 year old, 120 Film).
I don't think it was foam, though, as that it typically black. It really much looked like the right side of this - clear, gummy, slime:

The streaks could be underfixing. does it look like there are opaque, whitish or yellowish areas on the film? If not, its uneven developing caused by not enough agitation during developing.

Refix in fresh fix in a tray. Wash and dry.
If streaks are still there, there is contamination or more likely poor agitation, i.e. not enough. It is called bromide drag from incomplete replenishment . Forget being gentle. That is bad advice and is all over the internet.

I had similar problem posted here and got lots of advice. But only after reading the book The Darkroom Cookbook (page 39), I understand how agitation works. I suggest you agitate (inversions and twists gentle or rapid, no matter) initially for 50 secs or 1 full initial minute. Then 10 secs of every minute thereafter. The other advice I got from the forum and confirmed by the book is: have enough developer in the tank. Not only right concentration but total volume of it.

Yep, that might be it. I think for that film, I used the method that the Patterson tank manual recommended: Use their "Handle" to rotate the spool during the initial agitation. That does not include any inversions during the first minute.
I usually do proper agitation in the beginning so maybe that was the problem this time! It also explains the direction of the streaks.
Thanks!
