TF-4 Or Hypam For Film?

[tundra]

Back in the days when I first switched to PMK Pyro, I also switched to TF-4 as my fixer since the theory was that it would work better with staining developers.

How does Hypam work in this context? (Pycrocat, PMK. Rolo ...) Insofar as I use Hypam for all things paper, it would be easier to stock only one fixer (mixed separately for film and paper, of course) but I won't do that if Hypan is unsuited for negatives produced with staining developers.

It's fine. Been using it with Pyrocat-HD for twenty years.

Either Ilford Hypam or Rapid Fixer (they are essentially the same and work at the same pH) will work fine with pyro / catechol staining developers.

I've switched from TF4 even though it works fine. I use ammonium thiosulfate (Ilford Rapid Fixer) now because it works for film, dry plate, wet plate.

Me too: PMK for film, fixer is Hypam or Rapid Fixer. Never a problem.
