Since the dawn of photography people have been making portraits. The popularity of the Daguerreotype in the middle of the nineteenth century was due in large part to the demand for inexpensive portraiture. Studios sprung up in cities around the world, some cranking out more than 500 plates a day. The style of these early works reflected the technical challenges associated with 30-second exposure times and the painterly aesthetic of the time. Subjects were generally seated against plain backgrounds and lit with the soft light of an overhead window and whatever else could be reflected with mirrors.
As photographic techniques developed, an intrepid group of photographers took their talents out of the studio and onto battlefields, across oceans and into remote wilderness. William Shew's Daguerreotype Saloon, Roger Fenton's Photographic Van and Mathew Brady's What-is-it? wagon set the standards for making portraits and other photographs in the field.
In politics, portraits of the leader are often used as a symbol of the state. No matter where you are, in most countries it is common protocol for a portrait of the Head of State to appear in important government buildings. When portraits of the leader are used excessively, it becomes a sign of a personality cult.
In literature the term "portrait" refers to a written description or analysis of a person or thing. A written portrait often gives deep insight, and offers an analysis that goes far beyond the superficial. For example, American author Patricia Cornwell wrote a best-selling book titled Portrait of a Killer about the personality, background, and possible motivations of Jack the Ripper, as well as the media coverage of his murders, and the subsequent police investigation of his crimes.
The term portrait is also applied to the orientation of a rectangular page, painting or other graphic, denoting that the long axis is vertical. When the long axis is horizontal, it is said to be in landscape mode.From Wikipedia, the free encyclopedia.
