Lightpainting is basically when you set your camera to have a long exposure (like 15-30 seconds) and then use your flashlight to paint the scene. Wherever your flashlight lights up the scene your camera see that part of the scene...and only that part. The trick is to to create enough light (but not to much,) create even light (but no hot spots,) make it look natural enought to not feel like a street light (therefore paint unevenly,) and not catch yourself in the shot (wearing black and not pointing the light towards the camera help.) Mostly it is a game of trying, looking at the LCD, laughing, and trying again and again.
