Street photography is an approach to photography rather than a location, although the streets are the usual place that it happens.
“When I saw the photograph of Munkacsi of the black kids running in a wave I couldn’t believe such a thing could be caught with the camera. I said damn it, I took my camera and went out into the street.” Henri Cartier-Bresson
Alternatively it is refered to as no rules photography. The plethera of equipment (tripods, lenses,filters,lights etc etc) associated with “serious” photography is left at home, or better still in the camera store. Its just too heavy and bulky to cart around, takes way too long to set up and by the time it is set up the moment is gone.
Street photography is shooting from the hip.
Likewise the rules of photograph, the f stops, the shutter speeds, the rule of thirds etc etc are left in their dust jackets on Amazon shelves. By the time all the technical considerations are taken into account, the birdy is in another country.
Thank Canon, Nikon, Fuji et al for point & shoots.
It is just the camera and the photographer with their enthusiasm,...
