Whow the contrast is a striking comment. I had some notes from an earlier print of this neg and just copied the paper grade, I thought it was subject to taste but I indeed went one grade higher for this larger print.
I supose fogging also affects the sharpness when this is the case.
Can fogging acure sooner because the wall behind the enlarger is white (as is the ceiling) and I tent to use longer exposures (around 15 sec and up to 4 minutes when you add all burning.)
It's the only professional darkroom I know wich has white walls ceiling and floors.... They might have to ask lower subscriptions
