Paul, DK-50 is a Metol - Hydroquinone, Kodalk, Sodium Sulfite developer.
Maybe the current Kodak DK-50 Recipe contains a different amount of Sodium Sufite than the original version of DK-50?
All of the DK 50 I have on hand is old stock at least 20 years old, I am using it with 4X5 and some 6X9 so the gain has not been an issue. I might dunk some 35mm Forma Pan 400 to compare with Microdol X and Edwal 12. In the past I always DK 50 to be much grainer than HC 110 or Microdol X with 35, but I like the tones for 4X5.
Thanks for this. Nothing to do with grain but I thought that the scans improved in look as you moved from Kodak to Ilford to Ansco. The Ansco seemed to produce the punchier and more natural look in the dog's fur.
If all other things are equal and if every neg showed the same look then I would use Ansco on "looks" grounds alone.
You are right, the tests with Neopan SS processes in Kodak D 23, Ilford ID-11 and Ansco 90 developers resembles. If you go here: http://membres.lycos.fr/georgegrosu/9%20images.htm you can see better comparatives pictures between two negatives films (Neopan SS and Neopan 400) developed in Ilford ID-11. I thing you can see different grain films.
For me, the probleme of Neopiece SS it not the grain- I believe is the drawing of pictures.

I've never known D76 to be a "fine grain" developer. That's what Microdol-X and now (more or less) X-tol is for.
You can try pushing a stop and processing in Rodinal. There are quite a few Rollei & Leica users who love Tri-X with Rodinal. However, the grain is not "golf-ball" size as some users always stress, but rather a pleasing acutance which gives the film a certain look.
1:50 for 6.5-7min should be a good starting point for you.
It may be that as film has improved over the past few decades with finer gain developers like D 76 are now considered to fine gain, Microdal X very fine gain, and even DK 50 is now considered fine grain. I have a roll of Plux X from the 70s that had been frozen until last year, it appears to be gainer than the most recent version of Plus X, which match my negatives from the 70s and 60s.
Years ago I shot some 35mm fog scenes with Tri-X developed in HC110. These required overdevelopment to improve contrast. They turned out quite grainy which contributed to the mood of the fog. Perhaps someone else has more recent experience with HC110 overdeveloped.
HC-110 is not considered to be a "fine grain" developer, so that makes it a good choice. It is a very active developer requiring short development times, and is not the best choice if you want to exploit the most speed possible from your film. Overdevelopment will exaggerate grain through higher contrast more than, I think, through what I understand to be infectious development.
