How to shoot Northern Light

Northern Light could be breathtaking, especially if it’s the first time you see it. However, it’s relatively easy to catch with your camera, but there are some things that you have to have in mind. I will guide you through some of the most important steps so you can master your own Aurora creativity!

Equipment

Camera: Although it’s possible to photograph the Northern Light with a mobile phone, it’s easier with a DSLR or mirrorless digital camera.

Lens: Most prefer to use a wide-angle lens around 15-28 mm

Tripod: You need a tripod

Remote trigger: Optional. It’s also possible to use the self timer

Method

The Northern Light moves all the time, and it has to be dark when you shoot. That means that you have to use quite a long exposure time and a tripod to catch it.

Mount the camera on the tripod and compose the image. Chose to shoot with the lens wide open and choose an ISO setting between 800-3200, depending on how fast your lens is, how dark it is, and the nature of the Northern Light. The exposure time is the hardest; if the Northern Light is very active and moves fast – choose a shorter exposure time, maybe around 5 to 10 seconds. If it’s faint and does not move, you possibly have to select an exposure of about 15 to 25 seconds.

If you choose too long exposure time when the Northern Light is active, you lose definition and spreads all over the image. Optimal, you want to catch these beautiful windings, not a green “slime” without a definition covering all the sky.

It’s recommended to understand the relation between Exposure time, Aperture, and Sensitivity (ISO).

Earth Rotation and the 400-rule

The earth rotates once every 23 hours and 56 minutes. That has relevance for long exposure photography in that you will get star trailing in the images when the exposure time gets too long. What is too long?

A useful way to calculate that is to use the 400-rule. Divide the lens focal length with 400, and you get the maximal exposure time in seconds that you can use before you get star trailing in the image.

Example

With a 15 mm wide-angle lens, you can use 400/15=26,67 (27 seconds)

To be safe – stay a couple of seconds under these maximal values.

Some useful tips

Composition

A beginner is often very focused on the Northern Light in itself. Try to compose the image to create an exciting result! Northern light reflected in water could be stunning, for example. Or try to put an object in the foreground.

I would also recommend shooting in raw format, so you have greater opportunities to do some postproduction.
