Wanted: Photographers to shoot in exotic, sometimes inaccessible locales. Needed: Photographer to set up shop and work with clients among the icebergs and penguins of Antarctica, the bears and icy tundra of Hudson Bay, the apex predators on the wide-open veldts of the Serengeti or Maasai Mara. If this sounds like something you yearn for, how does the position of photography guide sound?
