Behold the Power of Gesture!
When you think of the elements of an image that make it successful and interesting most photographers immediately refer to the powers of color, form, texture, light/dark, and visual rhythm. There is another that is often overlooked: gesture. Unlike the other elements, gesture can't easily be preplanned into your composition; it's a fleeting thing. However, when you add in an interesting gesture to your frame, it's transformative.
