The most reliable starting point is manual exposure with your lens wide open (about f/1.2–f/2.8), a 2–20 second shutter speed, ISO 1600–6400, manual focus set on a bright star, white balance near 3500K, and RAW capture. Mount the camera on a sturdy tripod and use a timer or remote. These values are starting points: shorten the shutter when the aurora is moving quickly, and lengthen it modestly for a faint, slow display.
Starting settings at a glance
The northern lights can change brightness and shape from frame to frame, so no single exposure works for every display. Nikon’s 4 July 2025 guide recommends treating the following as a practical starting range rather than a preset that can be left untouched all night.

| Camera control | Starting point | Change it when |
|---|---|---|
| Exposure mode | Manual (M) | Keep control as the aurora brightens, fades or moves. |
| Aperture | Widest practical setting, about f/1.2–f/2.8 | Use a smaller aperture only if your lens cannot focus well wide open or you deliberately need less light. |
| Shutter speed | 2–20 seconds | Use 2–5 seconds for fast, sharply structured motion; move toward 10–20 seconds for a faint, slow display. |
| ISO | 1600–6400 | Raise it when a shorter shutter leaves the frame dark; lower it when highlights clip or noise becomes unacceptable. |
| Focus | Manual focus on a bright star | Set it once in Live View, then lock the focus ring. |
| White balance | Approximately 3500K | Keep it consistent for a sequence; RAW lets you refine color later. |
| File type | RAW | Use RAW whenever the camera supports it to preserve editing latitude and highlight-recovery options. |
Those ranges come from Nikon’s 2025 guidance and examples that include ISO 1600, 2000, 2500, 3200 and 6400 under different conditions. The right value depends on the aurora’s brightness, movement, your lens aperture and how much noise you will accept.
Why manual exposure is the safest starting point
Automatic exposure systems meter the scene they see, but they cannot predict whether the aurora will surge, fade or change shape during the next exposure. Mikko Lagerstedt, quoted in Nikon’s guide, puts it plainly: “Your camera cannot predict what the aurora will do, so manual settings are essential.” Manual mode prevents the camera from changing shutter speed or aperture unpredictably between frames, which makes a time sequence easier to match and lets you choose whether motion or brightness has priority.

Set the camera to M
- Turn the mode dial to M or select Manual exposure in the camera’s mode menu.
- Choose the widest practical aperture your lens provides.
- Enter an initial shutter speed in the 2–20 second range.
- Set ISO somewhere between 1600 and 6400, then make a test exposure.
- Review the frame at high magnification before changing more than one control at a time.
Change shutter speed first when the aurora’s structure is being lost to motion. Change ISO when you need to keep that shutter speed but the frame is still too dark. If bright ribbons are clipping, slightly underexpose or lower ISO; Nikon warns that overexposed aurora detail is difficult to recover.
Choose the aperture before you chase brightness
A wide aperture admits more light, which allows a shorter exposure and helps preserve the folds and rays in a moving aurora. Start around f/1.2–f/2.8, using the widest setting that gives you acceptable sharpness with your particular lens. A 14–24mm f/2.8 or 20mm f/1.8 class wide-angle lens is a practical match for the broad sky and low-light requirements, but the guide does not establish one universally best lens.
When a wide aperture matters most
- Fast display: Every stop of light can help you keep the shutter near the short end of the range.
- Faint display: The extra light may let you expose without pushing ISO as high.
- Foreground inclusion: A wide lens shows more landscape, trees, mountains, water or a cabin while still framing the sky.
Do not close the aperture simply because the scene is dark. If the frame is too bright, shorten the shutter or lower ISO before sacrificing the light-gathering advantage of the lens.

Shutter speed determines whether the aurora looks like defined ribbons or a soft green (or otherwise colored) wash. Begin between 2 and 20 seconds, then watch the live display and the first captured frame.
| Aurora behavior | Shutter approach | What to watch for |
|---|---|---|
| Fast, sharply structured rays or folds | Start near 2–5 seconds. | Longer exposures can merge separate ribbons into a blur. |
| Moderate movement | Try the middle of the range, then adjust in small steps. | Preserve enough detail without making the foreground too dark. |
| Faint and slow glow | Move toward 10–20 seconds. | Check that the aurora does not smear and that stars remain acceptably sharp. |
If a 10-second frame shows obvious motion blur in the aurora, move toward 5 seconds or 2 seconds and raise ISO to recover brightness. If a 2-second frame is clean but underexposed during a slow, faint phase, lengthen it toward 10–20 seconds before making a large ISO jump.
Balance ISO against detail and noise
ISO 1600–6400 is the recommended starting span. Lower values generally reduce visible noise but require more light from the aperture or shutter. Higher values make a short, motion-free exposure possible but can reveal more noise, especially in dark foreground areas.

A practical adjustment order
- Keep the aperture at its widest practical setting.
- Choose a shutter speed that matches the aurora’s movement.
- Raise ISO if the frame is still dark.
- If highlights clip, lower ISO or slightly shorten the exposure.
Nikon’s examples use ISO 1600, 2000, 2500, 3200 and 6400 rather than one fixed value. That spread is a reminder to evaluate each scene: a bright, active display may need less ISO, while a faint arc may require more.
Focus on a star in the dark
Autofocus often hunts against a nearly black sky. Use manual focus and set it before you begin a sequence.
- Switch the lens or camera to MF.
- Activate Live View and magnify a bright star on the rear screen.
- Turn the focus ring slowly until the star becomes the smallest, sharpest point.
- Stop turning the ring and leave focus locked for the session.
- Capture a test frame and inspect a star and the aurora at high magnification.
Recheck focus after moving the camera, changing lenses or handling the setup in the cold. Do not rely on the infinity mark alone; the exact sharp point can vary between lenses.
White balance and RAW capture
Set white balance around 3500K for a consistent cool night-sky color across a series. A fixed value prevents the camera from changing color interpretation between frames. RAW files retain the information needed to fine-tune white balance later. Lagerstedt’s Nikon guidance is direct: “Always shoot in RAW to retain full editing flexibility.”
RAW does not rescue a completely clipped aurora. Use it alongside careful exposure review, not as a reason to ignore highlight warnings or test frames.

If you must work without a tripod, use another solid support and avoid touching the phone or camera during the exposure. Stability is still essential even when the device has a night mode.
Adjust in the field without losing the display
Make one deliberate change at a time and capture another frame. The following decision table keeps the most important trade-off—motion versus brightness—clear.
| What you see | First change | Second change if needed |
|---|---|---|
| Ribbons are smeared or structure is missing | Shorten shutter speed, for example from 10 seconds toward 2–5 seconds. | Raise ISO to compensate for the reduced light. |
| Scene is faint, slow and underexposed | Lengthen shutter toward 10–20 seconds. | Raise ISO within the 1600–6400 starting span if the aurora remains too dark. |
| Bright areas have no recoverable color or texture | Lower ISO or slightly shorten the shutter. | Retake and inspect highlights at high magnification. |
| Stars look soft | Return to Live View magnification and refine manual focus on a bright star. | Check that the tripod and trigger method are not introducing vibration. |
Do not wait until the end of the night to inspect a frame. A small screen can make a blurred star look sharp; magnification reveals the problem while the aurora is still visible.

Scout the view in daylight
Find an open view toward the north and identify a foreground element that gives scale and context: trees, mountains, water or a cabin. Daylight scouting lets you place the horizon and tripod safely without relying on a headlamp while the display is underway.
Check the sky and activity forecast
Check cloud cover and solar-activity forecasts before leaving. A strong forecast is not a guarantee that the sky at your location will be clear, so use it to decide when and where to wait rather than as a promise of a visible display.
Pack for cold, wet equipment
- Charged spare batteries, because cold weather drains batteries faster.
- Empty memory cards for a long sequence of RAW files.
- Warm clothing and hand warmers so you can operate controls safely.
- A red-light headlamp to preserve night vision while setting up.
- A lens heater or another anti-fog solution to limit frost and condensation on the front element.
Watch the lens during the session. Frost or fog can make every frame look low-contrast even when focus and exposure are correct.

Camera and lens choices that support these settings
| Item | Why it helps | Limits or cautions |
|---|---|---|
| Manual-capable DSLR or mirrorless camera | Provides direct control of shutter, aperture, ISO, focus, white balance and RAW capture. | No body is established as universally best for every aurora condition. |
| Sturdy camera tripod | Prevents vibration during 2–20 second exposures. | Loose ground or accidental contact can still soften frames. |
| Wide-angle fast lens | A 14–24mm f/2.8 or 20mm f/1.8 class lens covers a broad sky and gathers light. | The guide does not provide a controlled comparison of lens models. |
| Lens heater or hand warmers | Helps limit frost and fogging in cold conditions. | Hand warmers should not press directly against the lens in a way that shifts focus or composition. |
| Timer or remote | Reduces camera shake at the moment of exposure. | A built-in self-timer is a workable alternative. |
Nikon’s guide names Z-series bodies and NIKKOR lenses as examples, but its settings are exposure principles rather than a claim that one camera system wins in every situation.
Recommended Free Tools
Smartphone method
A recent phone can record an aurora, especially from a dark location away from light pollution, but it still needs a stable support. Turn off the flash and use a timer where available.
iPhone
iPhone 11 and newer models provide Night Mode with an adjustable exposure length. Select Night Mode, choose the longest time that remains stable on your support, and avoid touching the phone until the capture finishes.
Google Pixel
Pixel phones can activate astrophotography mode when held still. The Associated Press described exposures of up to four minutes. Such a long exposure is intended for a stationary phone and a relatively slow scene; moving aurora detail can blur during that time.
Samsung phones
Newer Samsung phones offer an astrophoto mode through the Expert RAW app. Use a solid support, keep the flash off and allow the sequence to complete without moving the device.

Troubleshooting common failures
The aurora is too blurry
First determine whether the blur is in the aurora or in the stars. If stars are sharp but the ribbons are smeared, the shutter is too long for the movement; shorten it and raise ISO as needed. If both stars and aurora are soft, refocus on a bright star and check tripod stability and the trigger method.
The frame is dark
Keep the aperture wide, then lengthen the shutter if the display is slow. If movement prevents a longer exposure, raise ISO within the starting range. A dark foreground does not automatically mean the aurora is underexposed, so inspect the sky and highlights separately.
The brightest ribbons are clipped
Lower ISO or shorten the shutter slightly and make another frame. Overexposed aurora detail is difficult to recover, even from RAW, so protect the brightest structure before making the rest of the scene brighter.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The colors change between frames
Use a fixed white balance near 3500K rather than an automatic setting. RAW gives you additional flexibility when you process the sequence.
The lens is fogged or frosted
Use a lens heater or another anti-fog measure and monitor the front element. Keep spare equipment protected from abrupt temperature changes, and use hand warmers for your own hands rather than placing them where they can move the lens or tripod.
The camera stops during the wait
Cold weather can drain batteries quickly. Start with charged batteries, carry spares and keep replacements warm until needed. Empty memory cards prevent a full card from ending the sequence prematurely.
A repeatable field workflow
- Before leaving: Check cloud cover and solar-activity forecasts, charge batteries, clear memory cards and pack warm clothing, hand warmers, a red-light headlamp and anti-fog equipment.
- In daylight: Scout an open northern view and choose a foreground such as trees, mountains, water or a cabin.
- Set up: Place the camera on firm ground, mount the wide-angle lens and compose the sky and foreground.
- Configure: Select Manual exposure, the widest practical aperture, a shutter in the 2–20 second range, ISO 1600–6400, approximately 3500K white balance and RAW capture.
- Focus: Use Live View magnification on a bright star, refine focus manually and leave it locked.
- Trigger: Use a timer or remote, then capture a test frame.
- Inspect: Magnify stars, aurora structure and highlights. Correct focus or vibration before changing exposure.
- Track movement: Shorten the shutter for fast motion; lengthen it modestly for a faint, slow display. Adjust ISO to preserve the chosen motion rendering.
- Protect the setup: Watch for frost or fog, monitor battery capacity and change batteries or cards before they fail.
What “best” means for this subject
For northern lights photography, “best settings” means settings that match the display in front of you. A fast aurora rewards a short shutter and may require more ISO. A faint, slow arc can tolerate a longer exposure. A bright display may force you to lower ISO to protect detail. The same camera and lens can need all of these choices over one night.
