... mystery (at least to me):
Take a look at this photo:
I have two rolls (35mm) from different camera/lens combination developed recently in which a lot of the frames came out like this (see the overly-bright edges).
No problem with reeling the film, chemicals are filled to the brim (300ml tank).
I did the standard agitation (4 upside down and back movement per minute), standard time for the developer + film combination (clayton and arista ii/agfa 400), 2 min. stop bath, 4 min. fixing with a rapid fixer, Ilford method of washing (5,10, 20), no hypo, no squeegee, then 1 min. in PhotoFlo.
Please advice me on what's wrong...

Looks more like an in-camera light leak to me. Or in the film cannister: do you roll your own?
Does it appear on all frames? Is there any fogging between frames or on the edges of the negative?

To me it looks like a nice, uniform fogging from a light leak - either the canister or the developing tank being the guilty...

another example might help.
The Tank is in question...

If you are using plastic film reels:
It could be increased development of the negs near the edges, due to increased turbulance of the developer caused by the plastic rim of the reel during inversion agatation. I use plastic Patterson reels, but use rotational agitation rather than inversion. Inversion is typically done with stainless steel developing tanks and reels.

agitation issues. too much I believe. This happens with plastic or steel reels. are you giving it 30 seconds agitation at the start ?

I'd agree with Frank and newsgrunt. Have too many old negs like that myself.

I have actually had that same problem with too little agitation! I use metal tanks, and last year I tried using slow, gentle, agitation instead of the more vigorous agitation I have always used. I wanted to reduce graininess, which gentle agitation should do. Well, I got less grain, but my edges were really overdeveloped and it ruined a lot of good film. The ones that I really wanted I was able to fix in Photoshop but it took hours of work on each one to make them look uniform over the whole frame. I went back to my usualy agitiation. No more problems.

I had the opposite not long ago Christopher. Went back to 30 sec start then gentle inversion every coupla minutes. Gentle being a complete inversion about every second and a half or so for me. ymmv

With the White edges being on the Edge of the frame, leads me to believe that it is caused by some sort of light leakage from somewhere. You mention that you have multiple rolls of film from different cameras and different lenses, which makes me think it must be in the processing equipment or during the film loading prcoess onto your spiral into your tank. Have you processed anything after this? How was that? IMO - I dont think it's anything to do with the process or method, it looks more to me like a light leak from somewhere, but I could be wrong.

I got something similar when I forgot to put the spindle in a plastic tank. it was pretty sad.

I'm going to have to agree with everyone that said over agitation. Like Frank said, try rotation instead of inversion and see how the results are.

I've had this happen, and it was 35 years ago. I still use the same camera so I have ruled out light leak.

Looks like too even agitation to me. You must change agitation during developing a bit, agitation must not be too monotonous. And with 120, never invert. Hope this helps somebody.

With 120, never invert ??What would you recommend then ?
I've never heard that either. I have always inverted 120 film and never had problems with it. The uneven dveloping problems i had were with 35mm, which I wasn't agitating enough. 90% of my work is done with 120 film, all inverted during agitation.

What camera? Were you changing lenses? This reminds me of someone with a similar problem a while ago - it turned out to be light leaking past the seals along the channel the shutter curtains run in. That was on an M body.

Awhile ago I had a strange problem with my 120 negs, sometimes there was a slight narrow area that looked like little clouds on paper. I´m using a 5 -rolls Paterson tank, it can take 3 rolls of 120(or even 6, if you play a little). Inverting a full loaded tank creates heavy streams and even air bubbles, usually to the bottom and top reels, and only on one edge, the one that is closer to the bottom or top. This prolem started when I started using the big tank. Now I just turn the tank 45 degrees and back couple times. Nowadays I develop around 150 rolls of 120 a year, and I´m quite happy that I found the solution to this problem.
