Response to Verichrome Pan presoak produces green run-off

Jeff- Unless the presoak is doing something specific that you like, why presoak. Current wisdom is that it's better to get the developer evenly into the emulsion, rather than have it trade places with the water from a presoak. As for the color, various films have anti-halo dyes and other dyes that come out during soaking, development, fixing, etc., depending on what and where the stuff is. I'm sure the technology used in Verichrome and Tri-X is quite different, so the run-off color difference isn't suprising.
