I've found that Tri-X rated at 1600 in Diafine produces a very fine-grained, compensated image with very little loss of shadow detail. The two-bath developer is also very convenient to use because it takes 3 min. in "A' and 3 min. in "B", no matter what film stock you're using. Also, it's panthermic, that is, temperature may be anywhere between 65 to 75 degrees F. with no change in time requ(posted 8594 days ago)
