By drydown, are you saying that when the print dries it will look darker? So to compensate, you really need to make sure your proofs are dry before deciding on the proper exposure etc. right? Thanks.
Yes, but be aware that this pertains to prints on fiber paper. RC paper has little, if any, drydown. I use mostly Ilford fiber paper, and drydown is 2-3 days! So, if you're using fiber, print something with little or no detail in the highlights. Then, be patient. Let it drydown completely and see what you've got.
