Portrait photography, or portraiture, is a type of photography aimed toward capturing the personality of a person or group of people by using effective lighting, backdrops, and poses. A portrait photograph may be artistic or clinical. Frequently, portraits are commissioned for special occasions, such as weddings, school events, or commercial purposes. Portraits can serve many purposes, ranging from usage on a personal web site to display in the lobby of a business.
Modern senior portraits may include virtually any pose or clothing choice, within the limits of good taste. Students often appear with pets, student athletes pose in letterman jackets or their playing uniforms, and many choose fashion photography. Outdoor photos are popular at locations that are scenic or important to the senior. Picture proofs are usually available to view online the next day which are lower quality, unedited and often with a watermark of the studio. (Wikipedia)
