'Catch of the Day' by Thomas D Mangelsen: This is my most iconic image, copied more than any other – the split second before the grizzly moved his head and shut his jaws on the sockeye salmon. At the time, no one believed the picture was real. But it was shot on film, the result of planning and luck. I made the image at the now-famous Brook Falls, where the grizzlies congregate annually to feast on salmon coming upriver to spawn. Every day, I’d hike the two miles from my tent to the viewing platform, set up my tripod and focus on a group of bears stationed above the falls. They would stand for hours waiting for salmon to leap near enough to grab with their paws or catch in their mouths. The exposure, speed, depth of field and serendipity would be more critical than usual.
