Photography (pronounced /fәˈtɒɡrәfi/) (from Greek φωτο and γραφία) is the process, activity and art of creating still or moving pictures by recording radiation on a sensitive medium, such as a photographic film, or an electronic sensor. Light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a timed exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. Photography has many uses for business, science, art and pleasure.
Photojournalism is a particular form of journalism (the collecting, editing, and presenting of news material for publication or broadcast) that creates images in order to tell a news story. It is now usually understood to refer only to still images, and in some cases to video used in broadcast journalism or for personal use. Photojournalism is distinguished from other close branches of photography (such as documentary photography, street photography or celebrity photography) by the qualities of:
Timeliness — the images have meaning in the context of a recently published record of events. Objectivity — the situation implied by the images is a fair and accurate representation of the events they depict in both content and tone. Narrative — the images combine with other news elements to make facts relatable to the viewer or reader on a cultural level.
