well, street photography is about capturing decisive moments without staging them. This picture requires observation to be understood. To whom belongs the shadow on the wall? How could the photographer capture it without getting in the image? The shadow player captured with an amazing sharpness, the ball caught mid-air, the real player dressed as the shadow one making the shadow even more tricky...give a surreal feeling to the image that made it for me
Oh, please, be patient with this. This photo is absolutely brilliant! Search "street photography" on the net and on dA and after viewing 100 or so photos, come back to this. I guarantee you will see this photo in an entirely different way!
