I find the shape of the grains and impression of sharpness of a Delta 400 negative processed in Pyro better than that same film in any other developer I know. Rodinal works better for T-Max films, but for delta I found it less than ideal. To get speed out of that film, I use it in X-Tol, but the grain becomes much less pleasing.(posted 8551 days ago)I also live outside of the US, and ordered Pyro PMK from Photographer's Formulary. Very quick efficient service with reasonable shipping rates and excellent service. You can e-mail them at formulary@montana.com.
