Street
"The 'street' in 'street photography' does not refer to a location or a subject; it identifies an idiom. A street photographer walks into situations nobody controls in order to discover what can be made of them as pictures. She commits to contingency as a coauthor, as war photographers do, but her object is art, not news."
