I had difficulty in finding my own words to describe Street Photography and so referred to the Internet for inspiration. Even there, there were so many different definitions, but I thought the following was the most appropriate.
Street photography, a genre of photography that records everyday life in a public place. The very publicness of the setting enables the photographer to take candid pictures of strangers, often without their knowledge. Street photographers do not necessarily have a social purpose in mind, but they prefer to isolate and capture moments which might otherwise go unnoticed.
It is an aspect of photography that I particularly enjoy, as unlike a landscape or architectural scene which can be recaptured at will, what happens in that 1/250 of a second (or whatever) when the shutter is opened, is a “one-off” moment in time which will never be repeated. I also feel Street Photography is important, as it will document how this generation lived, for the benefit of the next.
