When I have tried black and white and got a good picture I often wished it were in color. Since day one color, for me, has been like M & Ms and T.V. We see in color.
Street photography is an important documentation of our time. Some of the most significant images in any art medium in the last 150 years have been made in the street by people like Henri Cartier-Bresson and Diane Arbus and Robert Frank. If that’s discouraged, in the long term it will be a substantial loss.
