Pretty cool, though. How often do you find yourself trying to explain aperture and shutter speed? I think the aperture and shutter speed graphics tell the story quite nicely for people unfamiliar with setting exposure manually. (Although I might have been tempted to show a tripod recommendation--well, no,...if 'twere me it would be table pod, kneepod, wallpod, tumbler pod, etc.--at least up through 1/15.) Thanks, Chris.
