Why Getting the Best Camera Settings for Aurora Borealis Makes or Breaks Your Shot
The best camera setting for aurora borealis is a combination of settings you dial in manually — and here’s a quick reference so you can get shooting fast:
| Setting | Recommended Value |
|---|---|
| Mode | Manual (M) |
| Aperture | f/1.4 – f/2.8 (as wide as your lens allows) |
| ISO | 1600 – 3200 (up to 6400 for dark skies) |
| Shutter Speed | 5 – 15 seconds (3 – 7s for fast-moving aurora) |
| White Balance | 3500K – 3850K Kelvin |
| Focus | Manual, focused to infinity |
| File Format | RAW |
The aurora borealis is one of the most breathtaking things you can photograph. But it’s also one of the trickiest.
The lights move fast. The sky is dark. And your camera’s automatic settings will almost certainly let you down.
The good news? Once you know the right settings, capturing the northern lights is much simpler than it looks. You don’t need a professional setup or years of experience to walk away with a stunning shot.
What you do need is manual control. The aurora is driven by solar wind and geomagnetic activity — it can shift from a faint glow to a blazing curtain of light in seconds. Your camera can’t predict that. You have to.
In this guide, we’ll walk you through every setting, step by step, so you can stop guessing and start shooting.
The Best Camera Setting for Aurora Borealis: A Step-by-Step Guide
To capture the magic of the Northern Lights, we need to take full control of our gear. Automatic modes are designed for daylight; at night, they will try to fire the flash or result in a black frame. The foundation of the best camera setting for aurora borealis is Manual Mode (M). This allows us to dictate exactly how much light hits the sensor.
Switch to RAW Format
Before we even look at the sky, we must ensure our camera is set to shoot in RAW format. Unlike JPEGs, RAW files preserve all the data captured by the sensor. This is crucial for aurora photography because it gives us the flexibility to adjust exposure and fine-tune colors during post-processing without losing quality.
Disable Image Stabilization
If you are using a tripod—which is non-negotiable for these long exposures—you should turn off Image Stabilization (IS) or Vibration Reduction (VR). When the camera is perfectly still on a tripod, the stabilization system can actually create a tiny bit of internal motion while searching for vibrations, leading to slightly blurry stars.
Monitor Your Histogram
Don’t rely solely on how the image looks on your LCD screen. In the pitch black of night, a screen can look incredibly bright, tricking you into thinking your photo is well-exposed when it’s actually too dark. Instead, use the histogram. We want to see a “hump” of data that isn’t smashed against the left side (underexposed) or the right side (overexposed). Pay close attention to the green channel; the aurora is often so bright in green that it can “clip” or lose detail even if the rest of the image looks fine.

Mastering Exposure: Aperture, ISO, and Shutter Speed
Getting the exposure right is a balancing act. The aurora is dynamic—sometimes it’s a faint, static smudge, and other times it’s a dancing corona that fills the entire sky. We use the “Exposure Triangle” to adapt to these changes.
| Aurora Condition | Aperture | ISO | Shutter Speed |
|---|---|---|---|
| Faint/Static | f/2.8 | 3200 | 15–20 seconds |
| Moderate/Moving | f/2.8 | 1600–3200 | 8–12 seconds |
| Bright/Fast | f/2.8 | 800–1600 | 2–5 seconds |
Choosing the best camera setting for aurora borealis shutter speeds
Shutter speed is perhaps the most critical variable. If your shutter is open too long (30 seconds or more), a fast-moving aurora will turn into a blurry green soup, losing all those beautiful “curtain” structures.
- Fast Aurora (3–7 seconds): Use this when the lights are dancing quickly. It “freezes” the motion and preserves the distinct vertical lines.
- Slow/Dim Aurora (10–25 seconds): Use this for faint glows to gather enough light.
- The 500 Rule: To keep stars as sharp pinpricks rather than blurry streaks (star trails), use the 500 Rule. Divide 500 by your focal length (e.g., 500 / 14mm = 35 seconds). However, for the aurora, we usually stay well under this limit to preserve the light’s structure.
If you’re new to balancing these, our night sky photography guide and night sky camera settings articles offer deeper dives into the mechanics of the dark.
Balancing ISO and aperture for the best camera setting for aurora borealis
We want to let in as much light as possible, as quickly as possible. This means using a wide aperture (a low f-number). An aperture of f/2.8 is the industry standard, but if you have a f/1.4 or f/1.8 prime lens, you can lower your ISO significantly, resulting in cleaner, less “noisy” images.
ISO makes your camera’s sensor more sensitive to light. While modern full-frame cameras handle high ISOs (like 3200 or 6400) beautifully, older or smaller sensors might show “grain” or noise.
- Moonlight Impact: If there is a bright moon, you can often drop your ISO to 800 or 1200 because the moon illuminates the landscape for you.
- New Moon: In total darkness, you’ll likely need ISO 3200 to 6400.

Achieving Sharp Focus and Natural Colors at Night
One of the most frustrating experiences is coming home to find a memory card full of blurry photos. Autofocus does not work in the dark.
How to Focus at Night
- Switch to Manual Focus (MF): Do this on the lens barrel or in the camera menu.
- Use Live View: Turn on your camera’s screen and find the brightest star or a distant light on the horizon.
- Zoom In: Use the digital zoom (not the lens zoom) to magnify that star on your screen.
- Adjust the Ring: Slowly turn your focus ring until the star becomes a tiny, sharp pinprick of light. If it looks like a “bokeh” ball, you’re out of focus.
- Tape it: Once you find infinity focus, some photographers use a small piece of painter’s tape to secure the focus ring so it doesn’t nudge in the cold.
Natural Colors and White Balance
While Auto White Balance (AWB) can work, it often makes the sky look too yellow or too blue as the aurora shifts. For the most natural-looking greens and reds, we recommend setting a custom Kelvin temperature.
- Kelvin 3850: This is a “sweet spot” that keeps the sky looking like night while making the aurora colors pop.
- Range: Generally, 3500K to 4000K provides a consistent, professional look.

Essential Gear and Smartphone Techniques
Beyond the best camera setting for aurora borealis, your physical gear plays a huge role in your success.
The Right Lens
A wide-angle lens (14mm to 24mm on a full-frame camera) is essential. It allows you to capture the massive scale of the sky along with a foreground element like a mountain or a cabin. This provides context and makes the photo much more compelling.
Tripod and Accessories
- Sturdy Tripod: Wind is common in aurora-watching regions. A heavy, stable tripod is a must.
- Lens Warmer: In cold, humid conditions, frost can form on your lens. A USB-powered lens warmer prevents this.
- Spare Batteries: Cold temperatures drain batteries rapidly. Keep 2-3 spares in an inner pocket close to your body heat.
Can I use a Smartphone?
Yes! Modern smartphones have made leaps in night photography. To get the best results:
- Use a Tripod: Even for a phone, you cannot hold it steady enough for a 10-second exposure.
- Night Mode / Astro Mode: Use the dedicated night setting. On many phones, this will automatically stack images to reduce noise.
- Manual Apps: If your phone allows, set the ISO to 1600-3200 and the shutter speed to 10-15 seconds manually.

Frequently Asked Questions about Aurora Settings
Can I use Auto White Balance for the Northern Lights?
We generally advise against it. AWB can fluctuate between shots, making a time-lapse or a gallery look inconsistent. Setting it manually to 3500K–4000K ensures your “blacks” stay black and your “greens” stay vibrant. However, if you shoot in RAW, you can always fix this later in post-processing.
Why are my aurora photos blurry?
Blurriness usually comes from three things:
- Camera Shake: Use a 2-second shutter delay or a remote trigger so you aren’t touching the camera when the photo starts.
- Missed Focus: Re-check your focus every 30 minutes, as temperature changes can cause the lens glass to expand or contract slightly.
- Wind: If it’s windy, hang your camera bag from the center hook of your tripod to add weight.
What is the best lens focal length for the aurora?
The 14mm to 24mm range is ideal. A 14mm lens gives you a massive sweep of the sky, while a 24mm lens is great for “tightening” the composition around a specific mountain peak or landmark. If you are using a “crop sensor” (APS-C) camera, remember the crop factor; a 10-18mm lens will give you a similar field of view to a 15-27mm on a full-frame.
Conclusion
At Pratos Delícia, we know that capturing the aurora is a “bucket list” item for many. While the technical side might seem daunting at first, the best camera setting for aurora borealis is simply a starting point. The most important thing is to get out there, find a dark sky location away from city lights, and be patient.
The aurora is a natural phenomenon—it doesn’t perform on a schedule. But when the sky finally erupts in color, and you see that perfect image appear on your screen, all the cold nights and technical tinkering will be worth it.
