Art Wolfe details the process he went through to get just the right photo of some Chinese fishermen. There were many false starts.
By the time I was ready for the next shot, the darkening evening sky balanced the light somewhat. A 16mm focal length endowed the image with the depth I wanted and, combined with an f16 aperture, ideal depth of field. Waning light necessitated a one to two second exposure. Although blurred moving birds ruined most of the shots, they blocked direct light from the lanterns. I was making progress.
Perhaps even more interesting that Wolfe’s process is the fishing method employed by his subjects; they use birds, not nets or poles:
For centuries fishermen on the Li River of Southern China have partnered with cormorants to catch fish. Each fisherman has a complement of half a dozen or so trained birds. The light of a lantern attracts the fish, and the cormorants return to the boat, fish in beak. They can’t swallow them because the fisherman fix a band around their necks, but they eventually get their share.
