Matching Quote

"Part of the portrait painter's art, we must be careful to note, is to produce a sort of synthesis, something more various, richer, than even an astute photographer (now or yesterday) can catch by snapping a shutter in a camera. The portrait painter must be skilled in human observation, he must actually be moved by his subject as well as by his profession. True, an ambitious photographer might spend as much clock time as a painter in "studying" his subject, looking for the right shade of mood and the right chiaroscuro to articulate it. Yet this method, the photographic one, must necessarily rely too much on the subject's timed cooperation, since, materially speaking, all the photographer can record is a single moment, no matter how tactically approached and psychologically prepared that moment be."
