You’ve seen them. Those neon green ribbons and deep magenta curtains draped across a star-studded sky, looking almost too vibrant to be real. You book a flight to Tromsø or Fairbanks, stand in the freezing cold for four hours, and finally, it happens. The sky dances. You whip out your phone, snap a picture, and... it looks like a blurry smudge of swamp water. Honestly, it’s heartbreaking.
Capturing decent photos of the aurora borealis is one of those things that seems straightforward until you're actually standing in the snow at 2:00 AM with frozen thumbs. The gap between what your eyes see and what a camera sensor records is massive. While our eyes are great at seeing movement, they are pretty terrible at seeing color in low light. Cameras are the opposite. They can drink in light for thirty seconds, revealing colors that weren't even visible to the naked eye. This is why some people feel "cheated" when they see the Northern Lights in person for the first time; they expect the neon saturation of a professional photograph, but they get a faint, ghostly grey cloud.
The Science of Light and Sensor Sensitivity
To get those crisp photos of the aurora borealis, you have to understand why the light is there in the first place. Solar particles are slamming into Earth's magnetic field. When they hit oxygen at lower altitudes (about 60 miles up), you get that classic green. If they hit oxygen much higher up, you get those rare, deep reds. Nitrogen produces the purples and blues.
But here is the kicker.
Your camera doesn't care about the "why." It only cares about photons. If you're using an iPhone or a Samsung, your phone is trying to do a million calculations per second to "guess" what the dark sky should look like. Most of the time, it guesses wrong. It introduces "noise"—that grainy, digital sand that ruins a shot. Professional photographers like Peter Zelinka or the folks over at SpaceWeather.com don't just "take" a photo; they manage an exposure.
Why Your Gear Actually Matters (Sorta)
You don’t need a $5,000 setup, but you do need a tripod. Even a cheap one from a gas station in Iceland is better than nothing. If your camera moves even a millimeter during a long exposure, the stars will look like little worms instead of points of light.
- The Lens: You want something "fast." In photography talk, that means a wide aperture, like f/2.8 or lower. If you’re shooting at f/5.6, you’re basically trying to look through a straw in a dark room.
- The Sensor: Full-frame cameras handle the dark better than "crop" sensors. They have larger pixels that can soak up more light without getting "noisy."
- The Battery: Cold kills lithium-ion batteries. Fast. Keep your spares in a pocket close to your body heat.
I’ve seen people lose the shot of a lifetime because their camera died thirty seconds after the lights turned purple. It’s brutal.
Setting Up the Shot Without Losing Your Mind
Most people think they should just put the camera on "Night Mode" and hope for the best. Don't do that. You need to go into Manual (M) mode.

First, set your focus to infinity. This is harder than it sounds. Modern lenses often focus "past" infinity. The best trick? Find a bright star or a distant streetlight, use your screen to zoom in digitally on that light, and turn the focus ring until the light is as small as possible. If the stars look like bokeh balls, your photos of the aurora borealis will be garbage.
Then, set your ISO. Start at 1600. If it’s really dark, go to 3200.
Now, the shutter speed. This is where the "art" happens. If the aurora is moving fast—curling and snapping like a whip—you want a short shutter speed, maybe 2 to 6 seconds. If you go longer, the movement will blur into a big green blob. If the aurora is just a slow, faint glow, you can go up to 20 seconds to let that light build up on the sensor.
The Composition Trap
A green sky is cool. A green sky over a shipwreck, a lonely cabin, or a jagged mountain peak is a masterpiece.
Basically, the sky is only half the story.
The biggest mistake beginners make is pointing the camera straight up. You lose all sense of scale. You want "foreground interest." This is why places like Kirkjufell in Iceland or the Lofoten Islands in Norway are so famous for photos of the aurora borealis. They provide the perfect "anchor" for the image. If you're in a flat area, find a pine tree or even have a friend stand in the frame with a headlamp. It gives the viewer's eye a place to start before they look at the sky.
Dealing with the Moon
Is the moon the enemy? Not necessarily.

A full moon will wash out the fainter auroras, making them hard to see. However, a 25% to 50% moon is actually a photographer's best friend. It lights up the landscape so your mountains aren't just black silhouettes. It turns the foreground into a visible, detailed part of the image without drowning out the celestial show. Honestly, some of the best shots I've ever seen were taken during a partial moon.
Post-Processing: Where the Magic (and Deception) Happens
Let’s be real for a second. Almost every "viral" photo of the Northern Lights has been edited.
When you shoot in RAW format—and you must shoot in RAW—the image looks flat and greyish when you first open it on your computer. This is because the camera is saving all the data without applying any "style" to it. You have to bring out the contrast.
You’ll want to nudge the white balance toward the blue/cool side. If your photo looks too yellow, it’s probably because of light pollution from a nearby town. You can also use "Dehaze" or "Clarity" in Lightroom to make the stars pop.
But don't go overboard.
There is a trend right now where people crank the saturation so high the trees turn purple and the sky looks like nuclear waste. It looks fake because it is. True photos of the aurora borealis have a natural elegance to them. The goal is to make the photo look like what you felt when you were standing there, not like a scene from a sci-fi movie.
Common Misconceptions About the Lights
One of the weirdest things people believe is that you can only see the lights in the dead of winter.

You actually just need darkness.
In places like Fairbanks, Alaska, or Northern Canada, you can start seeing the lights in late August. The weather is actually much better then, and you don't have to worry about your tripod sinking into three feet of snow or your breath fogging up the lens. In fact, some researchers suggest that the weeks around the spring and autumn equinoxes (September and March) are the best times for activity due to the "Russell-McPherron effect," where the Earth’s magnetic field aligns better with the solar wind.
Another myth: you need to go to the North Pole.
Actually, the "Auroral Oval" sits a bit further south. If you go too far north, you're actually inside the "hole" of the donut, and the lights will be to your south. Locations at about 65 to 70 degrees north latitude are the sweet spot.
Technical Checklist for Your Next Trip
If you’re planning a trip to get your own photos of the aurora borealis, here is the reality of what you need to do:
- Check the Kp-index, but don't rely on it. The Kp-index measures geomagnetic activity on a scale of 0 to 9. A Kp 5 is a "storm." But I’ve seen incredible, sky-filling displays at Kp 2. Local weather and "clear skies" are way more important than the Kp number.
- Use a remote shutter or a timer. Even the act of pressing the button with your finger causes the camera to shake. Set a 2-second delay on your shutter.
- Take off your UV filter. Those glass filters you put on the front of your lens to "protect" it? They cause "concentric rings" (Newton’s Rings) in the middle of your aurora photos. Take them off.
- Warm up slowly. When you go back inside your warm hotel or car, your lens will fog up instantly. Put your camera in a sealed Ziploc bag before you go inside. The condensation will form on the bag, not on the delicate internal electronics of your camera.
Why We Keep Chasing the Light
There’s something deeply humbling about standing under a sky that’s literally on fire with solar energy. It reminds you that we live on a planet with a protective shield, dancing in a cosmic wind. Taking photos of the aurora borealis is a way of trying to bottle that lightning. It’s a frustrating, cold, and often expensive hobby, but when you see that green glow appear on the back of your camera screen for the first time, all the frozen toes feel worth it.
It’s about patience. You can have the best gear in the world, but if the sun doesn't burp or the clouds don't clear, you're just standing in a dark field. That’s the nature of wildlife and landscape photography—you are at the mercy of things much bigger than yourself.
Actionable Steps for Your First Night Out
- Download the "My Aurora Forecast" app. It’s generally the most reliable for real-time solar wind data and cloud cover maps.
- Practice in the dark at home. Can you change your camera settings by touch alone? You don't want to be fumbling with a flashlight in the field, which ruins your night vision and annoys every other photographer within a mile.
- Focus on the stars first. Before the lights even show up, get your focus locked in and your tripod leveled.
- Watch the horizon. Most auroras start as a faint "arc" in the north. If you see what looks like a glow from a city that shouldn't be there, that's your target.
- Keep your eyes open. Don't spend the whole night looking through the viewfinder. Sometimes the best way to "capture" the aurora is to just put the camera down and look up.
Capture the RAW files, keep your batteries warm, and don't forget to look at the sky with your own eyes while the shutter is open. The data is on the card, but the memory is in your head.
