Considered by some to be a part of professional photojournalism, documentary photography captures images of real life, usually in the context of historical events, as well as the everyday. A distinguishing difference between the two is that documentary photography tends to chronicle an event, subject, environment, or topic for an extended period of time, adding context to a particular storyline. Photojournalism usually deals with a shorter-term, more “breaking news” style of photography.
Sometimes shot in B&W for that timeless look, documentary photography can also be achieved by amateur or artistic photographers. Another popular subset of this type of photography can be found in the world of academics. Conservation photography and street photography may also be considered a part of this genre, but can also stand alone as separate categories.
