With high water in the rivers in Katmai this year, brown bears did a lot of swimming and snorkeling for fish. This resulted in a lot of shaking off the water once emerging from dives. Backlighting offers some interesting contrast in these situations. This shows what a shutter speed of 1/800 does for that kind of motion. It does not completely freeze the water, but enough to reveal a slight tail on the water drops, which capture a little more backlight. Not like I thought this completely through at the time, but it is a pretty good setting. 1/1600 sec would have frozen the drops pretty good.
