Took this photo while passing through this carnival (mainly to show my 3-month-old the bright lights and excitement). The light wasn't very good and I had no tripod, hence the noise and lack of specific detail.

That's physics more than math. As far as the photo, it lacks clarity, and I think more contrast is needed -- I almost misssed the figure in the foreground (maybe I was supposed to).
