Street photography is the spontaneous act of capturing moments unfurling around a photographer when s/he is out and about on the streets. It is the art and science of capturing life as it passes by. Street photography is done mostly candidly, without revealing one’s position or intention; a reason why it is often referred to as candid photography.
Street photography requires a fast shutter speed, ideally, something that has a quiet mode to avoid being conspicuous, a wide angle lens, preferably around 35mm or shorter, and an eye for the uniqueness that pops up around us from time to time. Small compact camera bodies are very popular because they have a minimal presence and can be used effectively to get very close to the subject.
A majority of great street photography is published in black and white. Either they are shot in monochrome or processed to taste from color.
