Doing it. Done that. Have it already.
My nose works, too.
It's SO annoying an left of nose about 1/3 of way up needs a little more exposure and cropping is 1/8" off... or when toning isn't quite warm enough or a bit too warm, and it's a result of sepia first and selenium next.... basically fully toned so there's no more room for adjustment....
I gave up on dry down stuff. I wait until FULLY dry then evaluate. I can guesstimate fairly well but dry down affects differently depending on the density of the area. Overall impression of the image cannot be guessed accurately enough.
Time for coffee! (and a muffin)
