How to Photograph the Northern Lights: Settings, Focus and Timing
To photograph the northern lights, put your camera on a tripod, switch to manual mode and start with your widest aperture (f/1.8 to f/2.8) and an exposure of 2 to 10 seconds. Focus manually on a bright star, shoot RAW, and shorten the exposure the faster the aurora moves.
That is the whole recipe. What makes the difference between a sharp, detailed aurora and a soft green flow is how you adjust your shutter speed during the night. This guide covers the settings for different aurora conditions, how to focus in total darkness, which apps to use for planning, and how to keep your gear working at -20 °C. All examples come from our own nights in Finnish Lapland and Senja, Norway.
Key Takeaways
Starting settings for the northern lights: tripod, manual mode, f/1.8–f/2.8, 2–10 seconds, ISO to balance out exposure, white balance around 3500–4000 K, RAW.
Match the shutter speed to the aurora: 10–15 s for a faint, slow glow, 1–3 s for fast-moving curtains. Long exposures turn moving curtains into a shapeless green blur.
Focus manually. Magnify a bright star in live view and turn the focus ring until it is a sharp point. Autofocus will not work in the dark.
In Finnish Lapland, auroras appear on roughly every other clear, dark winter night, according to the Finnish Meteorological Institute. Clear skies matter more than a high Kp number.
Keep spare batteries in an inside pocket, and let the camera warm up slowly in a closed bag before you open it indoors.

Tip 1: Set Up Your Camera Before It Gets Dark
Do the setup in your room, with light, not in a frozen forest with a headlamp. Switch to manual mode (M) and RAW. Turn off image stabilization, because on a tripod it can introduce blur.
Set the screen brightness down by two or three steps. A bright screen in the dark makes every image look better exposed than it is. Check the histogram instead. Tape over any red or green status lights on the camera body if you are shooting near other people.
For lenses, a fast wide-angle is ideal: 14–24 mm at f/2.8 or faster. A kit lens at f/3.5 or f/4 works too. You just need a higher ISO or a longer exposure.
Tip 2: Focus on a Star, Not on Infinity
This is where most first aurora nights fail. Autofocus cannot find anything in the dark, and the infinity mark on most modern lenses is not true infinity. Turning the ring all the way gives you slightly soft stars.
Switch the lens to manual focus. Point the camera at the brightest star or a distant light, open live view and magnify it to 10x. Turn the focus ring slowly until the star is a small, sharp point. Then leave the ring alone. A piece of gaffer tape over the ring stops it from moving when you handle the camera with gloves.
Take one test shot, zoom into the image, and check the stars. Do this again if you change lenses or zoom.
Tip 3: Adjust Your Settings to the Aurora
The northern lights change constantly. A faint arc can turn into dancing curtains within minutes and fade again just as fast. Your shutter speed is the setting that follows the aurora. Keep the aperture wide open and use ISO to balance the exposure.
Aurora conditions | What you see | Starting settings |
|---|---|---|
Faint, slow glow | A pale arc, often grey to the eye | f/2.8, 10–15 s |
Moderate activity | Clear green bands, slow movement | f/2.8, 4–8 s |
Strong, fast curtains | Bright, moving rays and pillars | f/1.8–f/2.8, 1–3 s |
Moonlit landscape | Brighter sky, visible foreground | f/2.8, 5–10 s |
White balance on Auto often makes the sky too blue or the green too yellow. Set it manually to around 3500–4000 K for a natural night sky. Since you shoot RAW, you can fine-tune it later.
A useful rule for stars: if you want them as sharp points, keep the exposure under about 500 divided by your focal length (full frame). At 14 mm that is about 35 seconds, at 24 mm about 20. In practice the aurora usually forces you much shorter anyway.
Tip 4: Compose With a Foreground
A sky full of green with nothing else is impressive on the back of the camera, but might be boring on a screen. Add a foreground: snow-covered spruce trees, a frozen lake, a cabin, a person with a headlamp. In Lapland, the classic subject is the tykky trees, spruces bent under thick crown snow.
Put the horizon in the lower third of the frame and leave most of the space for the sky. If the aurora is directly overhead, which happens in Lapland, point the camera straight up and shoot the corona, the point where all rays seem to meet.
For a person in the frame, ask them to stand still for the full exposure and light them briefly with a dimmed headlamp for one second. With a 3-second exposure that is easy. With 15 seconds, they will be blurry.
Tip 5: Know When and Where to Look
According to the Finnish Meteorological Institute, auroras appear on about half of all clear, dark nights in central Lapland, around Levi, Ylläs and Saariselkä. In Kilpisjärvi in the far north it is about three in four. That leads to the most useful advice in this article: in Finland, Sweden and Norway, the cloud forecast matters more than the aurora forecast.
Many visitors stare at the Kp index and stay inside when it shows 2 or 3. That is a mistake this far north. Kp measures global geomagnetic activity. On NOAA's scale, Kp 3 means a quiet aurora and Kp 5 the start of a geomagnetic storm. A "quiet" aurora is often clearly visible over Lapland. Check the cloud radar first. If there is a gap in the clouds, go out.
Most activity happens around midnight, from about 22:00 to 02:00. Be outside and set up before that. Auroras often start as a faint, grey arc to the north that looks like a thin cloud. Take a test shot with your smartphone. If it is green on the screen, it is the aurora. The camera sees colour long before your eyes do.
Move away from town lights. Even 10 minutes on foot or by car out of a village makes a visible difference in contrast.
Apps and Tools to Plan Your Aurora Night
You need two kinds of information: is there aurora activity, and is the sky clear? No single app answers both well, so we use a small set.
For aurora activity in Finland, start with the Finnish Meteorological Institute’s Auroras and Space Weather page. It shows the probability of seeing auroras across Finland. For live data, the ISES Regional Warning Centre Finland shows the current geomagnetic activity at each measuring station. When the station nearest to you turns red, auroras are likely if the sky is clear. That’s our signal to get dressed and go out.
For a broader view, the NOAA Space Weather Prediction Center gives a 30-minute aurora forecast and the Kp outlook for tonight and tomorrow. On your phone, My Aurora Forecast puts the Kp index and a forecast map in one place. It’s useful as a quick check, but in Lapland don’t let a low Kp keep you inside.
For clouds, use a forecast that splits cloud cover into low, medium and high layers. Thin high cloud often still lets the aurora through, but low cloud blocks it completely. Clear Outside shows exactly that, hour by hour, together with moonrise, moonset and the time it gets properly dark. Windy App is useful for watching cloud bands move across the map, so you can see where a gap is heading.
PhotoPills helps with the composition. It shows where and when the moon rises, so you can decide whether you want a moonlit foreground or a darker sky. You can also check in daylight which direction a spot faces before you come back at night.
One practical tip: download the maps and check the forecasts before you leave the hotel. Mobile reception outside the villages can be weak.
Tip 6: Keep Your Gear Working in the Cold
Batteries are the first thing to fail. At -20 °C, a battery that lasts all day in summer can be empty within an hour. Carry two or three spares in an inside pocket close to your body, and swap them as soon as the camera warns you. A cold battery often recovers when it warms up again.
The second problem is condensation. When you bring a frozen camera into a warm room, moisture forms on and inside the lens. Before going inside, put the camera into its bag or a sealed plastic bag and leave it closed for an hour or two until it reaches room temperature. Take the memory card out first, so you can back up your images without opening the bag.
Don't breathe on the lens or the viewfinder. Your breath freezes onto the glass immediately. Wear thin liner gloves under your mittens, so you can work the buttons without exposing bare skin.
Can You Photograph the Northern Lights With a Phone?
Yes, if the aurora is reasonably bright. Use the phone's night mode, put it on a small tripod or lean it against something solid, and use the self-timer so your finger doesn't shake it. If your phone has a manual or pro mode, try ISO 1600–3200 and 3–10 seconds. The results won't match a camera with a fast wide-angle lens, especially with fast-moving curtains, but for a strong display a modern phone gets surprisingly close.
Common Mistakes When Photographing the Northern Lights
Exposures that are too long. Fifteen seconds on a fast aurora turns sharp curtains into a green fog.
Trusting the infinity mark. Focus on a star and check by magnifying a test shot.
Staying inside because of a low Kp. In Lapland, clear skies matter more.
Leaving long-exposure noise reduction on. It doubles the time per shot and you miss the peak.
Going inside with the camera unbagged. Condensation can keep the lens fogged for the rest of the night.
Worked Example: A Typical Night Near Levi
The cloud radar shows a clear gap from 21:00. The Kp forecast says 3. We leave at 21:30 and drive 10 minutes out of the village to a frozen lake with a line of spruce trees on the far shore. The camera is already set up: manual mode, RAW, 20 mm at f/2.8, focus taped on a star, white balance 3800 K.
At 22:15 a faint arc appears to the north. It looks grey. First test shot: ISO 3200, f/2.8, 12 seconds. The screen shows a soft green band. Around 23:00 the arc brightens and starts to move. We drop to 6 seconds, then to 3 seconds and ISO 4000 as rays start dancing overhead. Twenty minutes later it fades back to a glow and we go back to 10 seconds. Three battery changes, about 400 frames, and the five best ones are all from the short, fast phase.
FAQ
What camera settings should I use for the northern lights?
Start withf/1.8 to f/2.8 and 2 to 10 seconds on a tripod, in manual mode and RAW. Use shorter exposures for fast-moving auroras and longer ones for a faint glow. Adjust your ISO to balance out exposure.
How do I focus my camera at night for the aurora?
Switch to manual focus, magnify a bright star in live view and turn the focus ring until the star is a sharp point. Then tape the ring so it doesn't move.
What Kp index do I need to see the northern lights in Lapland?
Often none beyond a quiet level. In Finnish Lapland, auroras appear on about half of all clear, dark nights, so clear skies are more important than a high Kp value.
When is the best time to photograph the northern lights in Finland?
From autumn to early April, between about 22:00 and 02:00. The Finnish Meteorological Institute rates March and early April as especially good, partly due to more stable weather.
Can I photograph the northern lights with my phone?
Yes, when the aurora is bright. Use night mode, a tripod or a stable surface, and the self-timer.
