Alex Kesselaar is an Australian photographer who specialises in light photography. You can contact him through Lightpaint Lab, a website he set up to promote his light photography services to local and international businesses.
In this documentary by Nate “Blunty” Burr, Alex hosts a night-time workshop on light photography on Bondi Beach and demonstrates the techniques he uses in his work.
Alex describes light painting as:
“A photographic technique in which images are made by moving a light source through the frame of a long exposure photo.”
To make similar images, you need a tripod and a camera capable of capturing long exposures. A digital SLR is your best option. If you’ve only got a smartphone but want to try light photography, check out apps like Slow Shutter Cam for the iPhone or Camera FV-5 Lite for Android.
You also need one or more light sources such as steel wool (take a look at these cool examples of steel wool photography), LEDs, torches, and flames.
If you’re not sure how to set up your camera, Alex recommends setting the aperture at f9, the ISO at 100 and using an exposure time of at least five seconds.
