Orcas. Killer Whales. In my mind, the unquestionable king of the ocean. I photographed these majestic mammals in the polar winter, in the Lofoten Islands of Northern Norway. The orca migrate to these islands every winter in search of millions of herring that seek protection in the narrow fjords. With about 10 minutes of daylight each day and blistering cold conditions, this was without a doubt my toughest shoot to date.
