RE: Lagrange cyanotype
Have to correct a mistake I've made below:
The iron salt used in -Rex is not Ammonium Iron(III) Oxalate as in
Lagrange formula -> so it's not essentially Cyanotype-Rex...
Nevertheless, results seem to be similar according to Stane's
description ;) Perhaps that's the fact which caused the confusion in my
Sorry for the inconvenience.

This is essentially what our TK calls "Cyanotype-Rex" - except for
slightly different solution strengths. I had bad luck with this type of
formula: strange tonal response (flat and grainy midtones, stair-like
H&D curve) + blue stained highlights (maybe you'll find staining is less
by separating solutions).
