Nice shot and interesting links. I agree with all that was said, however rules are meant to be broken. I took this shot handheld from the ground looking up at the London Eye. Unfortunately, I did not take a monopod on this trip and a tripod would have been far too bulky. The key was treating the camera like a gun. Take a deep breath, let it out slowly until the image in the viewfinder stabilizes, and squeeze the shutter release so slowly that you should be surprised when it snaps.
