Aha! A reference print - that's a great idea. Having a print that has tonality that looks good in the intended light would help prevent overexposing the print. I will try that.
I understand your technique keeping the print for a while before reprinting a better version. It sounds like the
best approach to get excellent results. I'm afraid it will be a few years before I can do that. Currently I can only
sneak into the darkroom a few times a year for a very limited time. Maybe when the kids are out of the house, I'll try your approach ;-)
