The photographer is an armed version of the solitary walker reconnoitering, stalking, cruising the urban inferno, the voyeuristic stroller who discovers the city as a landscape of voluptuous extremes. Adept of the joys of watching, connoisseur of empathy, the flâneur finds the world "picturesque". Susan Sontag, 1977
Street photography, also sometimes called candid photography, is photography conducted for art or enquiry that features unmediated chance encounters and random incidents within public places. Although there is a difference between street and candid photography, it is usually subtle with most street photography being candid in nature and some candid photography being classifiable as street photography.
Street photography does not necessitate the presence of a street or even the urban environment. Though people usually feature directly, street photography might be absent of people and can be of an object or environment where the image projects a decidedly human character in facsimile or aesthetic.
