Some camera operators use 35mm cameras to film motion pictures, 16mm cameras to film documentary and industrial films, and videotape cameras to record news events for later showing on television. Most other photographers use a wide variety of cameras to achieve desired results. Besides cameras and lenses, photographers and camera operators use a variety of film and colored filters to obtain the desired effect under different lighting conditions. When taking pictures indoors or after dark, they may use electronic flash units, floodlights, reflectors, and other special lighting equipment. Some photographers develop and print their own photographs in the darkroom and may enlarge or otherwise alter the basic image.
Many photographers send their work to laboratories for processing.
In addition to the skilled use of cameras and accessories, photographers must be able to compose their pictures with creativity and style. Still photographers may specialize in a particular type of photography, such as portrait, fashion, or advertising. Portrait photographers take pictures of individuals or groups of persons and often work in their own studios. For special events, such as a wedding or christening, however, they take photographs in churches and homes. Portrait photographers in small studios, like other small business owners, frequently handle all aspects of their business.
