Photojournalism is a particular form of journalism (the collecting, editing, and presenting of news material for publication or broadcast) that employs images in order to tell a news story. It is now usually understood to refer only to still images, but in some cases the term also refers to video used in broadcast journalism. Photojournalism is distinguished from other close branches of photography (e.g., documentary photography, social documentary photography, street photography or celebrity photography) by complying with a rigid ethical framework which demands that the work be both honest and impartial whilst telling the story in strictly journalistic terms. Photojournalists create pictures that contribute to the news media, and help communities connect with one other. Photojournalists must be well informed and knowledgeable about events happening right outside their door. They deliver news in a creative format that is not only informative, but also entertaining.
Like a writer, a photojournalist is a reporter, but he or she must often make decisions instantly and carry photographic equipment, often while exposed to significant obstacles (e.g., physical danger, weather, crowds, physical access).
The practice of illustrating news stories with photographs was made possible by printing and photography innovations that occurred in the mid 19th century. Although early illustrations had appeared in newspapers, such as an illustration of the funeral of Lord Horatio Nelson in The Times (1806), the first weekly illustrated newspaper was the Illustrated London News, first printed in 1842. The illustrations were printed with the use of engravings.
The first photograph to be used in illustration of a newspaper story was a depiction of barricades in Paris during the June Days uprising taken on 25 June 1848; the photo was published as an engraving in L'Illustration of 1-8 July 1848.
