When you say "I didn't get much stain with pyrocat" do you base this on blue channel or UV densitometry?Originally Posted by Max
It is difficult to assess pyrocat stain visually - the practical question is: How does it print?
"The rollo pyro instructions say this post-fix soak is when most of the stain forms (I know nothing of the chemistry involved here)."
I haven't used rollo pyro, but pyrocat does the important (i.e. proportional) staining and tanning during development - not afterward.
Stain deposited post development is overall stain and not really useful.
