I spread the negs out on a light table and make my choices for enlarging. I'm just getting back into the darkroom after a long time (23 years) so I don't have a clue as to how many prints I might make. In the old days (early 70's) when I did commercial work I would print 200 or more 5x7 glossies a day to keep the publisher happy. Hard work, long hours but it paid well. Now that I'm older I could never keep up that pace.
