Jeff,
Your RH data more or less confirms what we have noticed. Too wet being too
weak seems to be correct as well. I talk to at least one ore more folks a
day about Ziatypes and the feedback I get from them also confirms this.
I find that the correct humidity on Cranes Platinotype can be detected by
lightly dragging your fingers over the print while drying with a cool
airstream. At one point the fingers will start to slide rather than drag.
Stop drying when that happens and it should be correct.
