How to shoot

How to photograph the northern lights with a phone

A recent phone is enough: what matters is keeping it still and a long exposure.

Night mode

Turn on the camera's night mode. An iPhone held perfectly still offers exposures up to 30 seconds by itself; on Android use "Night" or "Night Sight".

Tripod or support

The phone must stay still: a tripod, a backpack, the car roof. Use a 3-second timer so tapping the shutter doesn't blur the shot.

Manual mode

If you have "Pro": a 5–15 second exposure (shorter for fast-moving aurora), ISO 800–3200, focus at infinity, white balance around 3500–4000 K.

No flash, no lights

Switch off the flash and dim the screen. Step away from streetlights — eyes and camera adapt to the dark in 15–20 minutes.
