Photographing the aurora is far easier than most first-timers fear — the sky does the hard work, and your job is simply to hold the camera steady, let in enough light, and get the focus right. This guide distils what our guides coach travellers through on the snow, from full-frame bodies to the phone in your pocket.
The three settings that decide every aurora photo
Everything comes down to three dials working together: shutter speed, aperture and ISO. A workable starting point on almost any camera is f/2.8, ISO 1600 and a 10-second shutter. From there you react to what the sky is doing. A slow, structureless glow tolerates a longer shutter (15–25 seconds) and higher ISO (up to 3200). A fast, dancing display needs the opposite — drop to 3–6 seconds so the curtains keep their edges instead of blurring into a green wash.
Focus in the dark
Autofocus is useless against a black sky, so switch to manual. The reliable method is to point at the brightest star or a distant light, magnify the live-view image, and turn the focus ring until that point is as small and sharp as it will go — that is infinity. Tape or lock the ring so it does not drift, and check your first frame at full zoom before you shoot fifty more out of focus. This single step saves more aurora photos than any other.
Gear that actually matters
A sturdy tripod is non-negotiable; long exposures and handheld are mutually exclusive. A wide, fast lens — anything around 14–24mm at f/2.8 or brighter — captures the sweep of a display and gathers light quickly. Bring a remote release or use the two-second self-timer so pressing the shutter does not shake the frame. Most important of all in Arctic cold: spare batteries kept warm in an inside pocket. Lithium cells drain fast at minus twenty, and a warm spare swapped in will resurrect a "dead" battery.
Composition: give the sky a foreground
The photos people remember are not just green sky — they are green sky over something. A snow-laden pine, a frozen lakeshore, a cabin with a lit window, or a lone figure gives scale and story. Place the horizon low to hand most of the frame to the aurora, and look for still water or fresh snow to mirror the colour. Shoot RAW so you can lift shadows and correct colour later without the image falling apart.
Yes, your phone can do it too
Recent phones shoot the aurora surprisingly well. Turn on Night mode or a manual/pro mode, set the longest exposure it offers (often 3–10 seconds), and — this is the key — brace the phone on a mini-tripod, a wall or a bag. Tap to focus on a bright star, lower the exposure slightly if the green blows out, and use the timer to avoid wobble. It will not match a dedicated camera, but it will bring home a genuine, shareable shot.
A quick field checklist
Tripod up and level; manual focus set to infinity and verified; RAW enabled; start at f/2.8, ISO 1600, 10s; timer or remote on; batteries warm with spares; lens cloth handy for frost. Nail those before the display peaks and you will spend the good moments shooting rather than fumbling with menus in the cold.
