In photography the absence of light means the absence of any quality picture. A well lit subject is the aim of any photographer.
Lighting styles are therefore employed to make sure that such a goal is achieved. There are numerous ways through the desired lighting techniques can be achieved. In photography, the angle at which the light hits a subject is crucial. Therefore a photographer will make sure that light angles on the subject are at their very best, and this involves the placing of lights at certain angles in relation to the subject, with the aim of achieving a given effect.
Portrait and family portraits photography or portraiture in photography are photographs of a person or group of people that captures the personality of the subject by using effective lighting, backdrops, and poses. A portrait photograph might be artistic, or it might be clinical, as part of a medical study. Frequently, portraits are commissioned for special occasions, such as weddings or school events.
Portraits can serve many purposes, from usage on a personal Web site to display in the lobby of a business.
There are many different techniques for family or pet portrait photography. Often it is desirable to capture the subject's eyes and face in sharp focus while allowing other less important elements to be rendered in a soft focus. At other times, portraits of individual features might be the focus of a composition such as the hands, eyes or part of the subject's torso.
Additionally another style such as head shot has come out of the portraiture technique and has become a style on its own.
