Yeah, I wasn't clear about the photo. You've got to know it; it's a postwar French(?) shot of either someone descending down a staircase or riding a bicycle through an alley as visible down a staircase. It's black and white, and has an extreme overhead sort of look. It's a famous photo, hanging in the Tate Modern or something. Anyway, someone posted it on Flickr in one of the photo critique groups without identifying it. Not only did nobody know what it was, but to a man they lambasted its technique, composition, etc. It was actually pretty hilarious.
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.
