Photojournalism involves using photography to tell visual stories for mass media. Unlike personal or artistic photography, photojournalism aims to communicate factual information to unknown audiences. While the field was not formally defined until the 1940s, photography is now essential for conveying news stories. Photojournalists work for newspapers, magazines, agencies, or freelance, covering events around the world through images. Their skills at capturing the moment visually can strongly impact how the public remembers historical events.
