Key Facts
- Start with aperture wide open (f/1.4–f/2.8), ISO 1600–3200, shutter speed 5–15 seconds
- For fast-moving corona aurora, shorten exposure to 3–5 seconds and raise ISO
- A wide-angle lens (14–24mm) with fast aperture (f/2.8 or wider) is the ideal aurora lens
- A sturdy tripod is non-negotiable — any camera movement during 5–15 second exposures ruins the shot
- Always shoot RAW for maximum post-processing flexibility with aurora colors and noise
- Use manual focus on a bright star via Live View, then lock the focus ring
- The strength of the aurora (check the app) determines your settings — brighter aurora allows lower ISO and shorter exposures
The Settings Cheat Sheet
Aurora photography settings are not fixed — they shift with every display. A bright, fast-moving corona demands different settings than a faint, slow arc on the horizon. But you need a starting point, and these settings will get you in the right range for most conditions.
Aperture: Set your lens to its widest aperture. If you have an f/1.4 lens, shoot at f/1.4. If your fastest lens is f/2.8, use f/2.8. Aurora photography is one of the few situations where you genuinely need every photon you can gather. Stopping down even one stop — from f/1.4 to f/2 — halves the light reaching your sensor, forcing you to compensate with higher ISO or longer exposure. Sharpness in the corners matters less than capturing the light.
ISO: This is your primary adjustment lever once aperture and shutter speed are set. For bright aurora (Kp 5+), start at ISO 1600. For moderate displays (Kp 3–4), use ISO 3200. For faint aurora that is barely visible to the naked eye, push to ISO 6400. Modern full-frame sensors handle ISO 3200 with acceptable noise. Crop sensors introduce more noise at the same ISO, so expect to do more noise reduction in post-processing.
Shutter speed: This depends on how fast the aurora is moving. For active, fast-moving curtains and corona, use 3–5 seconds to preserve the structure and movement. For slow, diffuse arcs, 10–15 seconds captures more light without blurring the aurora into a featureless smear. As a general starting point, 8 seconds works well for most situations. Exposures longer than 15 seconds risk star trailing at wide focal lengths and will definitely smear any aurora movement.
White balance: Set to approximately 3500K for a neutral rendering of aurora greens and purples. Auto white balance can work, but it tends to shift between frames, making batch processing harder. Since you are shooting RAW (you are shooting RAW, right?), white balance is fully adjustable in post-processing — but getting it close in-camera helps you evaluate your shots on the LCD.
Choosing the Right Lens
The lens matters more than the camera body for aurora photography. A fast wide-angle lens on a five-year-old body will outperform a slow zoom on the latest flagship. Two properties define a good aurora lens: focal length and maximum aperture.
Wide-Angle Primes
The gold standard for aurora photography. A 14mm f/2.8 gives you a massive field of view that captures sweeping aurora displays from horizon to overhead, plus enough foreground to anchor the composition. A 20mm f/1.8 is arguably the most versatile aurora lens — wide enough for big displays, fast enough for low ISO, and sharp across the frame. A 24mm f/1.4 offers the fastest aperture in a practical focal length, excellent when aurora is faint and you need every bit of light. Any of these three will serve you well for years.
Wide-Angle Zooms
A 14–24mm f/2.8 zoom is the versatile alternative. You sacrifice one to two stops of aperture compared to the fastest primes, but you gain the ability to quickly reframe without changing lenses — valuable when the aurora shifts position and you need to adjust composition in seconds. The f/2.8 maximum aperture is fast enough for strong and moderate displays, though you will need higher ISO for faint aurora.
Why Wide Angle Matters
Aurora displays often span 90° or more of sky. A 50mm lens captures a narrow slice, missing the scale and grandeur of the display. Wide-angle lenses (14–24mm on full frame, 10–16mm on crop) capture the full sweep of the aurora while including foreground elements that give the image depth and context. Wide angle also allows longer exposures before stars begin to trail — at 14mm on full frame, you can expose for roughly 25 seconds before star trailing becomes visible.
Kit Lens Limitations
Kit lenses (typically 18–55mm f/3.5–5.6 on crop, or 24–70mm f/4 on full frame) can capture aurora during strong displays, but you are fighting the physics. At f/3.5, you need roughly 2.5 times more ISO than at f/2.8, and four times more than at f/1.8, to achieve the same exposure. That means ISO 6400 or higher, where noise becomes a significant problem. If aurora photography is something you want to pursue seriously, a fast wide-angle prime is the single most impactful upgrade you can make.
Essential Gear Beyond the Camera
Camera and lens are the starting point, but several accessories make the difference between a frustrating night and a productive one.
Tripod
A sturdy tripod is non-negotiable. Exposures of 5–15 seconds require absolute stability — any vibration during the exposure produces blurred stars and smeared aurora. Choose a tripod rated for the weight of your camera and heaviest lens, plus a margin for wind resistance. Carbon fiber handles cold better than aluminum (metal tripods in −20°C will freeze to bare skin). A ball head allows quick repositioning when the aurora shifts across the sky. Avoid center columns extended fully — they amplify vibration.
Remote Shutter Release
Pressing the shutter button introduces vibration, even on a solid tripod. A wired or wireless remote release eliminates this entirely. If you don’t have a remote, use the camera’s built-in 2-second timer — tap the shutter and let the camera settle before the exposure begins. Many mirrorless cameras also support smartphone remote control via Bluetooth or Wi-Fi, which works well in a pinch.
Spare Batteries
Cold weather is the enemy of lithium-ion batteries. A fully charged battery that lasts 400 shots at room temperature may die after 80 shots at −15°C. Carry at least two spare batteries and keep them in an inner pocket close to your body, where your body heat maintains their charge. Rotate batteries: when the one in the camera dies, swap it for a warm spare from your pocket and put the cold one back to warm up. It will recover some charge as it warms.
Headlamp with Red Mode
You need to see your camera controls, swap batteries, and navigate terrain in the dark. A headlamp with a red-light mode lets you do all of this without destroying the night vision that took 20–30 minutes to develop. White light from a standard flashlight or phone screen constricts your pupils and washes out your ability to see faint aurora. Red light preserves your adaptation to darkness.
Lens Cloth and Hand Warmers
When you move between a warm car and the cold outdoors, the front element of your lens will fog with condensation. A microfiber lens cloth lets you wipe it clear quickly. Chemical hand warmers serve double duty: keep your fingers functional for operating camera controls, and strap one to the lens barrel with a rubber band to prevent dew and frost from forming on the glass during long shooting sessions. Cold fingers are slow fingers, and fumbling with settings during a coronal display is a photographer’s nightmare.
Focusing in the Dark
Autofocus is useless for aurora photography. Your camera’s AF system needs contrast to lock on, and a dark sky provides almost none. The lens will hunt back and forth endlessly, often settling on the wrong distance. Switch to manual focus and take control.
The Live View method: Point your camera at a bright star or a distant light source (a communication tower, a lit building on the horizon). Switch to Live View and magnify to maximum (typically 5x or 10x). Manually turn the focus ring until the star or light is the smallest, sharpest point possible. This is your infinity focus point.
Lock the focus ring: Once you have achieved sharp focus, do not touch the focus ring again. Use a small piece of gaffer tape or painter’s tape to secure the ring in position. This prevents accidental bumps from shifting your focus during the session. Some lenses have a focus lock switch — use it if available.
The infinity mark is unreliable: On older manual-focus lenses, the infinity mark on the focus scale was generally accurate. On modern autofocus lenses, the focus ring typically travels past infinity. Rotating to the hard stop or aligning with the infinity symbol does not guarantee sharp focus. Always confirm focus visually through Live View magnification.
Recheck periodically: Temperature changes cause metal and glass in lenses to expand and contract slightly, which can shift the focus point over the course of a long session. If you have been shooting for an hour or more, or if the temperature has dropped significantly, take a moment to recheck focus on a bright star. It takes 30 seconds and can save an entire night’s work from being slightly soft.
Composition and Technique
Technical settings get light onto the sensor. Composition turns that light into a photograph worth keeping. Aurora photography rewards photographers who think beyond the sky.
Include foreground interest: A sky full of green light is impressive in person, but in a photo it often looks flat and lacking context. Trees silhouetted against the aurora, a mountain ridge, a calm lake reflecting the lights, a church or cabin — these foreground elements anchor the image and provide a sense of scale. The viewer’s eye moves from the familiar foreground up into the extraordinary sky, and the image becomes a scene rather than a patch of color.
Use the rule of thirds: Place the horizon at the lower third to emphasize a dramatic sky, or at the upper third when a reflection in water is the main feature. Avoid centering the horizon, which splits the image in a way that feels static. If the aurora has a strong vertical column or a bright focal point, position it at one of the intersection points rather than dead center.
Shoot many frames: Aurora conditions change by the minute. The intensity builds, the position shifts, colors evolve from green to purple and back. Take many exposures and vary your composition. What looked like a faint arc five minutes ago may suddenly explode into an overhead corona. Photographers who shoot continuously during active displays come home with far more keepers than those who carefully compose one frame at a time.
Try different orientations: Most aurora photos are shot in landscape orientation because it captures the widest view of the sky. But when the aurora is directly overhead or forming tall vertical curtains, portrait orientation captures the full height of the display. Switch back and forth as the aurora changes shape.
Time-lapse sequences: Set your camera to take continuous exposures using an intervalometer (built into many mirrorless cameras, or available as an accessory). Shoot one frame every 8–12 seconds for 30–60 minutes. The resulting sequence, compiled into a video at 24 or 30 fps, reveals the mesmerizing movement of the aurora in a way that still photos cannot. Time-lapse footage of a strong display is some of the most compelling aurora content you can create.
Panoramas: When the aurora stretches across the entire sky, a single frame — even at 14mm — cannot capture the full scope. Take a series of overlapping frames (roughly 30% overlap) across the display and stitch them together in post-processing. Panoramas produce ultra-wide-angle images that convey the immense scale of a full-sky aurora event. Keep your exposure settings identical across all frames for seamless stitching.
Post-Processing Aurora Images
Shooting RAW is the first step. Post-processing is where you realize the full potential of that RAW data. Aurora images almost always benefit from careful editing — but the goal is to enhance what the camera captured, not to create something artificial.
White balance: This is your most powerful creative tool for aurora images. Cooler white balance (3000–3500K) emphasizes the green tones that dominate most aurora displays. Warmer white balance (4000–4500K) shifts greens toward yellow and brings out purple and magenta tones in the upper portions of the aurora. There is no “correct” white balance — adjust to taste, but avoid extremes that make the image look unnatural. Because you shot RAW, this adjustment is completely lossless and reversible.
Noise reduction: Long exposures at high ISO produce noise, particularly in the dark areas of the sky. Apply luminance noise reduction carefully. Too little leaves visible grain; too much smooths out fine detail in the aurora structure and stars. Start with moderate luminance noise reduction (around 25–40 in Lightroom) and increase only if necessary. Avoid high levels of color noise reduction, which can shift the subtle color gradients in the aurora.
Clarity and vibrance: A modest boost to clarity (5–15) enhances the contrast within the aurora structure, making the curtains and rays more defined. Vibrance boosts muted colors without oversaturating already-vivid tones — a better choice than the saturation slider for aurora. Increase vibrance by 10–20 for a natural boost. Be cautious: over-processed aurora images with cranked saturation and clarity look garish and immediately lose credibility.
Stacking for noise reduction: If you shot a series of frames from the same position, you can stack them using specialized software (Sequator for Windows, Starry Landscape Stacker for macOS) to reduce noise without sacrificing detail. Stacking averages out random noise across multiple frames while preserving the consistent signal — the aurora and stars. The result is dramatically cleaner than any single frame, especially at ISO 3200 and above.
Software options: Adobe Lightroom and Capture One are the professional standards for RAW processing, offering precise control over every parameter. For free alternatives, darktable and RawTherapee provide comparable RAW processing capabilities. For stacking and panorama stitching, dedicated tools like Sequator (stacking) and Hugin (panoramas) produce excellent results at no cost.
Frequently Asked Questions
What are the best camera settings for northern lights?
Start with aperture wide open (f/1.4 to f/2.8), ISO 1600–3200, and shutter speed 5–15 seconds. Adjust based on aurora brightness and movement speed. For fast-moving corona aurora, use shorter exposures (3–5 seconds) at higher ISO. For slow, diffuse arcs, you can use longer exposures (10–15 seconds) at lower ISO for cleaner images.
What lens is best for aurora photography?
A wide-angle lens with a fast aperture is ideal. The most popular choices are 14mm f/2.8, 20mm f/1.8, or 24mm f/1.4. Wide angle captures more of the sky and foreground, while a fast aperture (f/2.8 or wider) lets in enough light for shorter exposures. A 14–24mm f/2.8 zoom is a versatile option that covers the sweet spot.
Do I need a tripod for northern lights photography?
Absolutely. Exposures of 5–15 seconds require a completely stable camera. Any handheld movement will produce blurred images. Use a sturdy tripod that can handle wind and uneven terrain. A ball head makes quick composition adjustments easier. Some photographers also use a remote shutter release or the camera’s built-in timer to avoid vibration from pressing the shutter button.
Should I shoot RAW or JPEG for aurora?
Always shoot RAW. Aurora images benefit enormously from post-processing — adjusting white balance, reducing noise, and recovering shadow detail. RAW files retain all sensor data, giving you far more flexibility in editing. JPEG compression discards information that is difficult or impossible to recover, especially in the shadow areas and color gradients that define aurora images.
How do I focus at night for aurora photography?
Switch to manual focus. Autofocus struggles in darkness and will hunt endlessly. Focus on a bright star or distant light using Live View at maximum magnification. Once focused, lock the focus ring with tape or switch the lens to manual to prevent accidental refocusing. Check focus periodically, as temperature changes can cause lenses to shift slightly.
Can I photograph aurora with a kit lens?
Yes, but results will be limited. Kit lenses (typically f/3.5–5.6) require higher ISO values (3200–6400) to compensate for the slower aperture, which introduces more noise. You can still capture aurora, especially during strong displays, but the image quality will be noticeably lower than with a fast prime lens. If you are serious about aurora photography, a fast wide-angle prime is the single best upgrade.
