Oh, you're talking about Henri Cartier-Bresson, yeah, it's the decisive moment. When all you've got is one shot, make sure the shot is at the right moment! Everything has to come together to make a great photo. People are so funny sometimes, especially when they love talking out their butt!
Yeah, exactly. Mario's Bike. Thanks for finding it!This looks contrived, which is not a bad thing. If this is a planned shot, it just didn't come out right. If you can round up Mario, I would do it again. This time put the camera on a tripod and use the smallest aperture possible to get the best DoF. What I would hope for is that the railings are sharp and that mario on the bike shows a blur. Must have the foreground sharp, though. Without that, the image will never fly.
