Four separate reels or two reels of two rolls per reel [ala Jobo]?
It's kind of hard to tell as the other rolls were more landscape/street so there is more "noise" to break up the pattern.You are developing four reels at a time? Does every reel have the same edge problem?
Was this roll at the top, or somewhere below?
To me it looks like it may have been at the top with incomplete coverage from the developer.
This statement has inspired me to discontinue using taller tanks. I bought a Paterson System 3 recently which holds about 1000ml of solution and develops 2 120 or 3 35mm. I realized it must be the long pour times that are giving me grief, not to mention that these taller tanks are not particularly suited to inversion agitation (HC-110 doesn't need any help producing foam). The goal was to save time developing an extra roll per session, but not at the cost of uneven development or inferior results. Working in the dark, for me, defeats the purpose of using a daylight tank. Time to get back to doing what works.However, for a large multi-reel tank it's usually better to fill the tank first and drop the reels in in the dark, cover and proceed in the light. At the end of developing, it would also be better to take all the rolls out at once, refill the tank (or use another one, ideally) with stop then put the rolls back in. But you can probably get away with emptying through the lid.
For the rest of it, fill and empty times don't matter.
The extended fill times can certainly give you problems with uniformity during development.
Thanks, that's the RZ67 with the 180mm lens, one small 20" soft box just to the left of the lens.By the way, ParkerSmithPhoto, your picture is really nice. What kind of lens are you using? And how did you light it?
So are you saying you were getting uneven results with SS reels or the Paterson? I remembered a few years back I was using Diafine in a Paterson system on a Unicolor base and managed to find a neg that had almost this exact same problem. Very faint, but there.This statement has inspired me to discontinue using taller tanks. I bought a Paterson System 3 recently which holds about 1000ml of solution and develops 2 120 or 3 35mm.

having fiddled with image to exagerate the problem it looks to me that this due to either some contamination from the film spool or bubbles/froth on the film which means it was probably the the top film of the four poking out of the developer.
Reel could have slipped up the column and not moved back after inversions.
I don't think its due to flow of chemical over neg edge.
Either use more dev in tank or make sure you rap tank hard enough on base after inverions to make all reels slip down on column as far as possible.
On the other hand the dark line at the edge of it suggests it might be film spool contamination. Not sure about this.

I'm using a Paterson tank and reels, and I'm getting exactly what you're getting as shown in the contrast-modified image. My regular combination is Acros 100 and HC-110 (dil. E, 68F, 8 min.) using inversion agitation. I have more than enough developer in the tank, and tests in room light clearly show foam bubbles clinging to the film, just under the top of the reel, which is fully submerged. I can bang the tank till it breaks, and I'll still get that. The only thing I've found that consistently prevents it is lateral agitation -- specifically figure-8 agitation, wherein the tank is never turned on its side or over but moved in figure 8's along a plane parallel to the ground. Still, I'm not totally convinced that this type of agitation isn't causing uneven development in other ways. I'm still testing. Further still, agitation isn't going to do anything to compensate for slow fill times.So are you saying you were getting uneven results with SS reels or the Paterson?

It's the Paterson Multi-Reel 3 currently available at B&H and elsewhere.
On the other hand the dark line at the edge of it suggests it might be film spool contamination.
It means you have got residual chemicals on the spool from the last time it was used. And photoflo is a prime candidate but could be fixer or anything else which that reel has been used in. i.e you have NOT cleaned it properly. But could just be air bubbles.What is "film spool contamination?" That's a new one for me.
