One of my friends recently posted this project on FB and it kind of captivated me. The neatest thing? There is no photoshop involved...just light painting and an amazing photographer, Denis Smith. He describes it like this, "The Ball of Light is created in a single exposure by swinging lights around. There is no “Photoshop” here at all. It is super challenging, and certainly adds a new dimension to long exposure photography."
Very inspiring. You can read more and see more photos at his website, Ball of Light
