Street Photography is all about capturing candid moments of people and all the objects you see on the street. The unnoticed clicks that goes around on street leaves a marvelous effect on the picture. Sometimes you also get to capture the excitement of people when they want to get clicked.
Street pictures have a tendency of catching the eyesight of the on looker. If I may term it, a monochrome picture of Street Photograph also displays colours in terms of expressions and the look in the eyes.
Street Photography is also about fearlessly capturing pictures on the street. Sometimes, it also involves breaching the personal space if capturing people on streets. It is all about the decision taken to capture that perfect and wow moment, note there is no reposing and there is no retake of that moment.
For me Street Photography also gives you a path to show your creativity and express yourself.
