My times for film in PMK and Pyrocat-HD are usually the same. I give Tri-X
roll film 12 minutes at 75 degrees, with an EI of 250. When I develop sheet
film by inspection my times generally fall between 10 and 20 minutes,
depending on developer temperature. This is for conventional silver
printing, though at the higher end of the contrast scale they often print
well on VDB also.
Recently I've been using the metol version of Pyrocat-HD with 10% hydroxide
for solution B. I call it Pyrocat-HDMV - high definition metol variant.
Gotta call it something...
