Thanks for the input. The grain in the ISO 400 samples processed in Rodinal posted on the Bergger site looks fine to me. But the mottling issue is a much a bigger problem. HP5+ has been my mainstay, and I just experienced the mottling on a recent roll for the first time.
Again, thanks for the link, good information there. A while back, I remember coming a cross a (German, maybe?) site that had examples of various film and developer combinations. Anyone know about that one?You might find this information useful, Pieter. It doesn't address your specific combination but does give a useful overview of the film in various developers

All the best
A while back, I remember coming a cross a (German, maybe?) site that had examples of various film and developer combinations. Anyone know about that one?
Maybe for 35mm. I like grain as long as it is accompanied by sharpness. That's why I use Rodinal and a condenser enlarger. This example of 120 Pancro 400 in Rodinal from Bergger's website seems fine with me. But I am concerned about the mottling mentioned
I’ve observed it on every 120 film I’ve used in the past 2 years. If you buy fresh film and use it within months of purchase, odds are better that you won’t see the problem, but I recently processed rolls (all within their freshness date) of Tri-X, TMY, Pancro 400, Delta 400, and FP4 and all of them displayed the issue to some degree.
Pancro 400 is the WORST when processed with Rodinal; clumpy coarse grain, loss of shadow information, blown out highlights, difficult to print, etc. Plain old D-76 1:1 is a better option, Xtol is good too. PMK is vastly superior.
How was the base fog in D-76 1+1, XTOL, and PMK? I was shocked at how high it was in Pyrocat-HD. Was still able to make a decent print though...never seen so much B+F!
I am specifically asking if anyone had rated Pancro 400 at 200 and processed it inRodinal, looking for developing times. What portion of the negative are you showing in your Delta 100 mottling example?If you’ve already decided you like the hard grain look of Rodinal, then I’m puzzled why you’d ask about this film/developer combo. It seems you’ve already made a choice.
As for the backing paper mottling/transfer issue, I’ve observed it on every 120 film I’ve used in the past 2 years. If you buy fresh film and use it within months of purchase, odds are better that you won’t see the problem, but I recently processed rolls (all within their freshness date) of Tri-X, TMY, Pancro 400, Delta 400, and FP4 and all of them displayed the issue to some degree. Some rolls were closer to their expiration date than others. (URL links to results from an expired roll of Delta 100 I shot in 2019 and processed two weeks ago: https://live.staticflickr.com/65535/50797307406_a028e62f82_b.jpg And no, I don’t typically wait two years to develop exposed rolls - this was found in a drawer in my darkroom)
My plan is to buy fresh 120 stock only when I expect to use it, and no longer keep a cache of it.
Andrew,
base+fog is highest when I develop in PMK, it seems. Its less in either D-76 or Xtol, and better still when processed with BER49 (Atomal49) but the differences are minor except the PMK negs, which have conspicuously more fog. Regardless of which developer you use, Pancro400 has the most base density of any film I currently use. (and the list includes pretty much all of the major brands/formulas)

Interesting. Thanks for that, Paul.
Andrew, out of curiosity I did a test this afternoon using Bergger Pancro 400 (with my Kodak Duo Six-20) and processed it in Divided D-23 to see how it affected contrast, base fog, etc. As it happens, the negatives were really nice and the base fog was lower than I expected. You might want to experiment with that developer as an option. However, the best frames came from exposures that set the ASA at about 160, which is how I rate it for PMK as well. Here is a sample image from the divided D-23 roll:

That's good to know as I do use D-23 when I develop Pan F. Thanks for letting me know!
Andrew, are you using the two part D~23 recipe on Pan F?
