I just looked at the archives and see a good bit of conflicting information on the subject.(posted 8294 days ago)The spec inside the box of Tri-X says to use 6 minutes at 20 C with TMAX developer for both ASA 400 and 800 ratings. Elsewhere here I read a general guideline which says to increase developing time by anywhere from 20% (1.2 minutes) to 1.5 minutes for a one stop push.
What's the real answer here?
