The simple act of opening and closing a camera shutter has the power to capture and preserve a moment. Whether it"s war victims fleeing burning buildings, a World Cup-winning goal or a protestor smashing a window, images can be loaded with information that tells the story of a specific location and situation in a specific fragment of time. Often, photos represent less than a second of life on Earth. The camera I work with, for example, can capture one 8000th of a second, fast enough to show the wings of a hummingbird in sharp definition.
