I can see where pulling back maybe a third of a stop would be advantageous, but I am quite happy with, at least for most exposures, just exposing the same amount. I really didn't lose much in the shadows at all.

Different darkroom, different humidity? Who knows. I don't want to over think it. I look at this as a lovely gift and my biggest concern is I want to avoid thinking I might have to go reprint 20+ years of pt prints

I really like what I have found with the brush. It's minimal, fast, non-messy. I think the wet might be more problematic. On the Platine, I can see easily if I have a smooth coat and good coverage.

What papers have you been using?
