Seeing before the fact

One of the most satisfying things for a photographer is to "see" an image in your mind, take the shot and then find that it works just the way you visualised it.

This happened to me with this shot.  I was standing at a bus stop, sheltering from the rain, watching the traffic pass.  I suddently "saw" a tightly cropped shot of cars and cyclists, quickly took out my camera and made this image.

It would be great if it worked out like this every time!
