It's a technique I'd first tried with Dave Black at the Photography at the Summit workshop a month ago.
What is light-painting? Well, in this set up it's a long exposure photograph using only a flashlight in a dark room to expose the 'subject'. It's an incredibly challenging technique, as no two photos look the same. Your flashlight is the only light source, and where you point and for how long, determines the amount of light falling on your subject.
Starting out, all I'm using is a modified LED mini flashlight that I had sitting around the house. How modified? Well, I used a piece of gaffers tape to create a narrower cone of light so I could make the beam less spread out and more directional. So while there are some nicer flash lights that Dave recommends that come with their own snoot, by no means is it a necessity.
Get your flashlights ready and start painting!
All these are 30 second exposures at f11, ISO 200
