Nothing special here but notice my streak-free sky! (Rolleiwide, FP4+, D-76 1-1):
Well, I developed a couple of rolls of FP4+ in D-76 doing a pre-soak yesterday. Still looking over the negs but the ones I've seen so far with big expansive skies have no indications of such streaks so we may have solved my issue. I'll continue the pre-soak method with more developing this week and see if it holds. Funny though these seem to have more dust than usual but I cannot see how pre-soaking would cause that issue.
Also interesting in that past threads about whether to pre-soak or not, the arguments would go on and on but I cannot recall anyone pointing out my issue in the argument or discussion.
Thanks all for taking the time to reply to this thread. Very appreciated.
I always tilt my stainless steel tanks about 25 degrees or so when I pour in the developer. I got accustomed to doing that because an early tank had some sort of divider vane under the lid, but my main intent is to make it easy for the air to escape. In my experience, with some of the plastic lids on a level tank, the air burping out bogs down the fill process.
As i reach full, I back off on the tilt a bit so as not to spill (though I do use quantities that leave some air space in the tank for better agitation. I'd say a fill is on the order of ten seconds and follows a very defined flow path. Combining that with developing times of 7 or 8 minutes or longer (HC110 1+63 mostly), I think results are evened out quite sufficiently. I do not presoak.
My 1.3 cents (2 after taxes),

That's pretty much how I do it too. And I'd say 70% I have no issues. It's that 30% of the time that ticks me off and it's always some photo with lots of sky! Perhaps some change in my technique of pouring might help, who knows. In the meantime I'll keep the variables to a minimum and only change to doing a pre-soak and hope I do not see it any more. If I do I'll revisit the issue again.
Thanks again all, VERY much appreciate everyone's thoughts.
For this project I used stainless steel reels in a basket.. think I could do about 20 rolls at a time and I was very consistent in my process- used the Kodak method of agitation in large tank.. there was no issue about chemicals getting to the film.. If you keep findind this problem to still show itself .. and if you feel strongly its the lack of agitation or flow of chemistry to the emulsion fast enough then you may want to give this approach a try.
I have zero problem with this method... when I let assistants do this - they get bored really fast and I end up with surge issues on edges of film so its something you definately need to do yourself as you
will only be screwing yourself if you agitate improperly..
Before Jobo this was my go to method for 20 years. In fact I made extra cash at school by processing the evening runs of student film... Ahhh I was destined to be a lab rat working for others..

Can you describe what you mean when you say you "used the Kodak method of agitation in large tank" and how you assistants failed to use that method and produced surge marks? It would be interesting to know. Thanks.
Alrighty. Got a hold of a JOBO 2502 reel so as to load and develop two rolls of 120 at a time in my JOBO 2521 tank (which until now I used exclusively with a 2509n reel for 4x5). After practicing every night for a week in daylight with two old expired rolls of Shanghai GP3 and then with the same rolls as "dry runs" in the changing bag I finally braved it with a couple non-practice rolls of FP4+. Other than taking a little more time than I'd usually take to load on SS reels (which should get better with more experience) I developed them in D-76 1-1. Problem SOLVED. My skies are as even-toned and smooth as a baby's tush. Looks like I'll be doing my 120 film development this way from now on. Just loaded two more rolls of film for development (Delta 400) and the loading went much faster this time.
