Night photography ipsum
Night photography refers to photographs taken outdoors between dusk and dawn.
Night photographers generally have a choice between using artificial light and using a long exposure, exposing the scene for seconds, minutes, and even hours in order to give the film or digital sensor enough time to capture a usable image. With the progress of high-speed films, higher-sensitivity digital image sensors, wide-aperture lenses, and the ever-greater power of urban lights, night photography is increasingly possible using available light.
Long exposures and multiple flashes
The long exposure multiple flash technique is a method of night or low light photography which use a mobile flash unit to expose various parts of a building or interior using a long exposure.
