What is a moment? Over the course of a year, only a few mornings combine warm water, cold air, and still winds to give mist rising off the water -- a moment of the year. Within one of those mornings, there's only a brief time between the sun lighting up the mist and the same sun burning it off -- a moment of the day. And watching the ducks swim away, there's only a moment when 4 of the 5 turn to offer a profile to the camera -- a moment withing a moment within a moment.
