This study traces the development of night photography, from February 7, 1839, when the effect of the moon on a Daguerreotype was first recorded by Alexander Von Humboldt, to the present. The contributions of the following photographers who advanced the field of night photography are discussed: Margaret Bourke-White, Paul Martin, Brassai, Bill Brandt, Felix H. Man, Jacob August Riis, Weegee, Lewis Hine, and Eric Solomon. Artificial lights utilizing calcium, oil, mercury, and magnesium, as well as gas and electricity; flash bulbs; and electronic flash units are all considered as sources of illumination for night photography as are the natural light sources, moonlight and the Mexican firefly. A bibliography about night photography is also included. (LL)
