I mixed up the 1l package of Dektol I bought by mistake last week. I ran some Tri-X 400 in it. 4 minutes @22˚c ... I like the grainy results .. I think I'm gonna buy some more Dektol Thanks for everyone's suggestions I'd like to dip some Presto 400 in it, but I cannot find any dev times. Anyone got a ballpark figure? How similar are Tri-X & Presto?
