I've been chasing even development with dilute developers on Fuji HR-U x-ray film.
I've gotten good results with 510-Pyro at 1:100 for 5 minutes but Rodinal at 1:100 looks even smoother. The catch is that I'm getting these little pinpoint dots in the background with Rodinal. Does anyone know what might cause this?
I'm developing using inert gas burst agitation in a 1-gallon vertical tank with the film on hangers. I've run about 30 batches of film with 510 pyro ranging from 1:100 to 1:250 dilution and haven't seen the dots:
However, both of my tests with Rodinal have suffered from it. Could a slight contamination with pyro from the previous cycle cause this?
