This is a practical evening of light painting led by Caroline Wright and you need to bring a long your camera and tripod. If you have a cable release that would also be of benefit you will also need a low ISO of 100 to 200 and dial in a narrow aperture of about F11 (this is opposite to what you would usually use for night photography when you need as much light in as possible). The Shutter speed needs to be between 10 to 30 seconds. See what changing the light balance will do but try Tungsten or Incandescent but try the others to give warmer or colder effects to your image.
