Street photography is very special in the sense that it highly relies on chance, candidness and big crowds. The bustling stream of chaos in public places provides plenty of that and much more, if you're keen and patient enough to wait. And there are plenty of photographers that wait for the perfect moment to pass them by, like any other passerby.
The Street Photographers Foundation's goal is to feature powerful pictures by up-and-coming and professional photographers alike, and they happily do it on their Instagram account which by now has more than 550k followers, which is a testament to the quality of content that they constantly provide.
