Street photography, known also as candid photography, is the photography done in public places and is conducted for the art of enquiry that features unmediated chance encounters and random incidents. When talking about street photography we don’t necessary need the presence of the street or the urban environment. Street photography can be done just as well in rural areas or public buildings; while documentary photography usually refers to a popular form of photography used to chronicle events or environments both significant and relevant to history and historical events as well as everyday life. Documentary is typically covered in professional photojournalism, or real life reportage, but it may also be an amateur, artistic, or academic pursuit.
So street photography is not the same thing as documentary photography. Although they are linked, and some would say that they are similar to a certain point, they are certainly not the same thing. So, until which point could we say they are connected?
