Great photo opporunities! I *love* taking pictures of cool shadows and any kind of light that is blocked in distinct or fun patterns. You can find great images lurking in and around shadows. You have to be careful -- your eye sees twice as much tonal range as your camera does -- so the camera will tend to polarize the light and darks into ranges lighter and darker than your eye sees. In other words, your best bet is to find soft shadows or areas where the light falls on medium toned surfaces. Here are some cool shots I took of shadows at a professional baseball game.
