In an effort to study a genre of photography that baffles and perplexes me to no end, from time to time I try taking a "Street Photography" shot. I look at it in color, then in B&W, back and forth, back and forth and still I don't know if one or the other is better than the other or the one. Maybe neither, maybe both. I wonder how good "Street Photographers" know when they've taken a good shot?
