Response to Verichrome Pan presoak produces green run-off

Coloured run-off is completely normal after pre-soak. HP5+ has nice deep green, APX has purple, some other films have black. Pre-soak is not useless, especially with larger formats. Some report softer development, which is understandable when you see that agitation has impact on contrast, especially in th first half minute. By pre-soaking you postpone the rapid and perhaps uneven absorption of the developer by the emulsion.
