Photographing at night can be fascinating because we lose some of the control over what happens in front of the camera. Over a period of time the world changes; rivers flow, planes fly by, clouds pass and the earth's position relative to the stars is different. This accumulation of time and events, impossible for the human eye to take in, can be recorded on film. For the photographer, real can become surreal, which is exciting. During the day, when most photographs are made, scenes are usually viewed from the vantage-point of a fixed single light source, the sun. At night the light can come from unusual and multiple sources. There can be deep shadows which act as catalysts for our imagination. There is often a sense of drama, a story about to be told, secrets revealed, actors about to enter onto the stage. The night has vast potential for creativity.
