Does it matter?

This shot should have never happened. It was a mistake of sorts. I basically wanted to photograph the man much sooner then he appears in this shot. I fumbled with the camera and got this at the last instant. It was nothing like I had envisioned. It turned out much better then it would have if I had managed to be a more competent photographer.

Which makes me wonder..........

How many of pictures we regard as masterpieces are really unintended mistakes?
