Thilo-
Is the magenta color cast obvious (and in what tones)? I've exclusively used the 3-bath for all of my chromes, and I've mixed various Fuji and Kodak films in different combinations (not intentionally, just in consideration of economics). I've not noticed any color casting as described. And no apparent color cross over when printing, either (on Ilfochrome). I use a Jobo system, 38 deg. temp and same time for all films. I rate Velvia at 40 ASA because it seems to need a little more exposure (and I prefer less development to avoid contrast increase). Is everyone adding the additional time necessary after the first batch is run (I do)?
