Starter settings
- Use a tripod or stable support
- Switch to manual focus and verify sharp stars
- Open the aperture as wide as practical
- Start around ISO 1600–3200
- Try a shutter speed around 5–15 seconds
- Use a shorter exposure when the aurora moves quickly
- Carry spare batteries inside a warm pocket
| Aurora condition | Starting shutter | Starting ISO | What to watch |
|---|---|---|---|
| Bright and fast | 1–5 seconds | 800–1600 | Avoid blurred structure |
| Moderate | 5–10 seconds | 1600–3200 | Balance movement and noise |
| Faint and slow | 10–15 seconds | 3200 or adjusted | Focus and camera stability |
The three settings that control the result
Aperture controls how much light reaches the sensor, shutter speed controls both brightness and movement, and ISO amplifies the recorded signal. Change one setting at a time and check the histogram as well as the rear-screen preview.
A very long exposure can turn a structured, fast-moving aurora into a featureless green cloud.
Focus before the display becomes strong
Autofocus often struggles with a dark sky. Switch to manual focus, magnify a distant light or bright star on the screen and adjust until it is sharp. Infinity is a starting point rather than an instruction to turn the ring as far as possible.
Check focus again after moving the tripod or changing lenses.
A practical starting setup
Use manual mode, shoot RAW when available, open the lens to a low f-number and begin around ISO 1600–3200 with a five-to-fifteen-second exposure. Take a test frame and react to the actual sky.
Bright moonlight, snow and strong aurora may require a lower ISO or shorter exposure.
Phone photography
Modern phones can produce useful results in night mode when held completely still. Use a small tripod, avoid digital zoom, clean the lens and tap or lock focus on a distant point when the camera allows it.
A phone may combine several frames automatically, so moving aurora can look softer than it did in person.
Composition matters more than green sky
Include mountains, a shoreline, a cabin or a person to give scale. Keep the horizon level and leave enough room for the aurora to develop.
Use a dim red light around other photographers and do not repeatedly shine a bright torch into their frames.
Cold-weather camera management
Cold reduces battery performance. Carry charged spares inside an inner pocket, avoid breathing on the lens and protect the camera from snow.
When returning indoors, condensation can form on cold equipment. Place the camera in a closed bag before entering and allow it to warm gradually.
Should you book a photography tour?
A photography-focused tour can help with camera setup, composition and portraits while also providing transport. Check whether the guide teaches settings, supplies tripods or simply sends a photograph taken for you.
Choose based on the service you actually want; neither photography support nor a road chase guarantees the aurora.

FAQ
What shutter speed should I use?
Start around five to fifteen seconds and shorten it when the aurora is bright or moving quickly.
Can a phone photograph the northern lights?
Yes, particularly with night mode and a tripod, although results and controls vary by model.
Should I use autofocus?
Manual focus is more reliable after you set it carefully on a distant light or star.
