[EXPERT TIP ] SET YOUR TRIP PHOTOS ABLAZE WITH LIGHT PAINTING Get Glow


A few years ago a friend and I jumped at the opportunity to spend a few days in the backcountry of Algonquin Park on Thanksgiving weekend. After setting up camp on Misty Lake, dusk turned to night at the early hour of 6:30 p.m. With dinner finished and site chores complete, I grabbed my new DSLR to experiment with some long exposure shots. To include ourselves in the photos, we took turns standing extremely still, while one of us illuminated the other with a headlamp. Several successful shots later, my fascination with light painting was born. Light painting uses a slow shutter speed and


various light sources to create color and design in an otherwise darkened image. During a long exposure the shutter of the


camera remains open and allows all available light to hit the sensor. If you do this for a second or two in bright conditions, the image will turn out overexposed or even white. However, in dark conditions, all available light is recorded so if you walk across the frame with a light source you create a bright line. Or, if you bathe your friend in a headlamp’s glow they become visible standing in the dark. With the immediate feedback of being able to view photos on your digital camera you can really fine-tune the look. There are two ways to paint with light. The first

is to aim the light source towards the camera lens. Using a focused beam, with this technique you can trace outlines of boats or tents, draw forest creatures or write words in the air like you did with sparklers as a kid (just remember to write letters backwards). Even though you are in the camera’s field of vision, so long as you keep moving and you’re not illuminated, you won’t show up in the image. The second way to light paint is to stand back


from the subject with the light source pointed away from the camera. This technique is perfect for creating broad highlights in an otherwise dark image. During the shutter release use your light source like a brush to paint the parts of your image you want to highlight, such as a tree, camper or canoe. For example, to illuminate your campsite against a starry sky, set your exposure to capture the sky then shine a broad beam of light across the site for a fraction of the time the shutter is open. Too much bright light and you’ll overexpose the foreground. Once you wrap your head around these two


methods you can draw pictures and words or bring attention to different areas of the scene, harnessing light to build the image you want.

The Basics STEP 1


Find a dark place to shoot. Your location doesn’t need to be pitch black. In fact, a dusky light will help create context for your image, illuminating background features like the horizon or tree line.


STEP 2


Use a tripod to eliminate camera shake and avoid blur. Decide on the focal point of the image.


STEP 3


Bring a light source to play with. It can be a glow stick, headlamp, sparkler or anything else that gives off light. LED flashlights and laser pointers provide a bright and direct beam of light, which can make words and drawings in your photos crisper than a diffused light source.


STEP 4


Using manual camera settings, set your camera up for a long exposure. Start with an exposure of 10 seconds and adjust from there. The longer the exposure, the more time you’ll have to create your image.


STEP 5


Experiment with different light sources, reviewing often and adjusting your shutter speed and painting methods.
