Watch the video: Light painting tips – how to photograph light orbs
Shooting light orbs is a great way to give your long-exposure twilight shots a unique twist. It’s one of those effects that ensures everyone who sees the results is going to ask, “How did you do that?” The answer is quite simple: you swing a piece of string with a torch attached and create these wonderful floating light spheres.
There are plenty of suitable locations for this technique, from coastal scenes and landscapes to cityscapes and derelict interiors. We found this Seventies-style multi-storey car park to be ideal – the concrete urban scene is just begging to be reinvigorated with a colorful light globe or two.
In principle the technique is pretty easy to master, but it does take a bit of practice before you start producing good orbs. It’s a question of trial, error and patience. So, using nothing more than a tripod, a cable release, a camera, some string and a flashlight, here’s how you photograph light orbs…
01 When and where
Just after dark is the time for this technique. If you get the timing and weather conditions right, you can capture a lovely blue hue in the sky. Get to your scene before dusk so that you can set up while there’s a still a little light; this will also make composing your image much easier.
02 The set up
The exposure will last for about a minute, so a tripod is essential. As you’ll need to switch the shutter speed to Bulb mode for exposures longer than 30 seconds, a cable release is vital so that you can lock your shutter open. Start with an aperture of f/8 and ISO200.
03 Long exposure tips
Take a test shot with a one-minute exposure to see what the overall exposure looks like. (You’re not creating a light globe at this stage.) You can use the Bulb mode for long exposures and time them manually.
You’ll need a torch or flashlight – we’re using a Maglite with the bulb exposed. Simply attach it to a piece of string about one meter long. It’s worth experimenting with other types of torch; LED lights and some powerful bike lamps can make fantastic light orbs.
05 Swing it
Turn your flashlight on and, keeping the light concealed, walk into the frame to the point where you want the sphere to appear. Once you’re in position, let the torch fall and start swinging it in a full circle. As you’re swinging it, move your body through a full 360 degrees.
06 Don’t stop moving
It’s important to keep your body moving so that it’s not recorded in the shot – wearing dark clothing will help prevent you appearing in the frame. Unless you’re very lucky you probably won’t nail the technique in your first shot, so be prepared to practice and take plenty of shots!
