Michael Neff has combined light, shadow and chalk to create an innovative form of sidewalk art. This chalk series outlines the shadow of everyday objects and highlights the negative presence of trees, fences, railings, whatever you may find on the streets of New York. Not only is this a brilliant idea, but the photographs themselves are also well-composed and aesthetically pleasing. Upon looking at his website, you'll also find Michael Neff as a photographer who has a great eye for night images and details.
