'Wading back into printing & haven't done MF before this week. (Thank You, Mark!) As I imagine trying to doge & burn w/ any complex composition, 10s just isn't enough time. The 80mm Nikkor stops down to f45, but aren't I losing clarity to diffraction going to the next smaller apertures? 'Don't know if there are other ways to lessen exposure & lengthen exposure time to allow for manipulation of values.
