One of the first subjects that I remember trying to capture as a teenager with my first SLR camera (film) was light trails created by cars on a busy road near my home.
I’d seen this type of shot in a photography magazine and was impressed by the eye catching results.
Light Trails continue to be popular subject matter for many photographers and they can actually be a great training ground for those wanting to get their cameras out of manual mode and to experiment with shooting in low light at longer exposures.
Following area few examples of light trail shots as well as some practical starting point tips for those wanting to give it a go.

There is not just one particular type of camera and kit that you’ll need to capture light trails – however it is important to have a camera that allows you to have some control over exposure settings – particularly those that allow you to choose longer shutter speeds. This means you need a camera that has the ability to shoot in either full manual mode and/or shutter priority mode (something that all DSLRs and manypoint and shoot cameras have).
You’ll also need a tripod (or some other way to making your camera completely still) as you’ll be shooting with long shutter speeds which will make shooting handheld pretty much impossible.
Not essential but helpful to have with you are lens hoods (to help block lens flare from ambient lights), remote shutter release cables or wireless remote controls, patience and some warm clothes if you’re going out on a chilly night.
At the most general level photographing light trails involves finding a spot where you’ll see the light trails created by cars, securing your digital camera, setting a long exposure setting on your camera and shooting at a time when cars will be going by to create the trail of light. Of course it’s a little more complicated than this – but the general factor behind it is longer exposures that will enable the car/s that create the trails to move through your image.
While there are a lot of tips that could be shared on the topic of photographing light trails – the main thing I learned in my early days of attempting to create these types of images was to experiment extensively. The beauty of digital photography is that you can do this with no extra cost to yourself and can get instant results (unlike when I did it on film and had to fork out for film and processing – not to mention wait days to see my results).
Photographing light trails is not difficult – it’s as simple as finding virtually any road with cars going down it once the sun goes down. But getting a shot that grabs attention means putting a little more thought into choosing your location, thinking about timing and framing your image. Here are a few tips on how to set your shot up:
Having said this I’ve found that I usually shoot at shutter speeds between 10 and 20 seconds (which gives cars time to move through the frame) and with apertures in the mid range (start with something around f/8).
The key is to start with something in the range above and to take a few test shots to see how the exposure works. You’ll quickly realize whether your shots are under or overexposed and whether the length of the exposure is long enough to let cars travel through the frame in the way that you want.
If your shots are overexposed – close your aperture down (increase the f stop number) or if your shots are underexposed open it up (decrease the f stop numbers). If you want the car’s lights to go further through the frame go for a longer shutter speed and if you want it to travel less through the frame shorten it.
Keep in mind that aperture impacts depth of field. If you need to go with a larger aperture you decrease the depth of field and more of your shot will be out of focus.
There is no right or wrong way to time your shot. Hitting the shutter just before a car enters the frame and releasing it just after it leaves the frame can create a lovely unbroken line – but sometimes shooting with shorter exposure times while the camera is in the frame can be effective also. Once again it’s about experimenting with different timings and seeing what effects it has.
Many digital cameras have a mode on them called ‘bulb’ mode that allows you as the photographer to keep the shutter open as long as you wish. This can be very handy in this type of photography to time your shots with precision. If you use this you’ll want to be using a remote shutter release to stop any camera movement while the shutter is open.
