Dennis Calvert shares a really neat light painting technique on his blog that he calls “Man on Fire.” It basically involves creating a darkened silhouette by firing a remote flash behind a subject to overexpose the background behind them, and then “painting” in the silhouetted area with some neat little light wands.
I’m sure you could do this with subjects other than people and with light wands other than the ones Dennis uses. The result, I think, is pretty spectacular. Because the background is blown out, bits of light trail that go outside of the silhouette area become wispy and look very cool.
Believe it or not, the image is straight out of the camera, no post-processing or alterations at all.
Go check out the whole article on Dennis’s blog where you will also find a time-lapse video of the making of the image, which is pretty neat in its own right.
