I think this is an amazing photo - I love the exposure and the contrast on it. The textures are spot on fabulous and the expression and posture of the man are wonderful at communicating his intense attention to his work. I don't think many folks are going to connect it to the challenge of habits, but that aside it's a great candid.
excellent compostion. i love that the front turntable is spinning wildly, while the back one is not in motion. nice contrast. a fisheye lens would have blown the competition away on this shot. a little more depth of field would have been nice, but overall i like it.
it's pity, you should use a better algorythm to resize your pictures, like bilinear... you get a lot of broken lines with stairs and it renders the picture less smooth... i like the idea of the disk that's turning !
