In the Agfa data sheet they give times for Tri-X in Rodinal at dilution of 1:25, 1:50 and 1:100 (e.g. 20m @ 20C at 1:100, EI 400), but for HP5+ they only give data for 1:25. 1:50 is "Not Recommended" and there isn't even a table entry at all for 1:100.(posted 8246 days ago)Is there really such a difference between Tri-X and HP+ in Rodinal? I've heard that T-grain films don't do well in it but I'm suprised data for HP5+ is left out.
