The Short Version: Aurora Photography Settings at a Glance
For a typical KP5–KP7 aurora storm from a dark-sky location (Bortle 3–4), these settings give you a solid starting exposure on most cameras:
| Setting | Slow/Faint Aurora | Active Aurora | Fast/Intense Storm |
|---|---|---|---|
| Shutter Speed | 20–25 sec | 8–15 sec | 1–4 sec |
| ISO | 1600–3200 | 800–1600 | 400–800 |
| Aperture | f/1.8–f/2.8 | f/2.0–f/2.8 | f/2.8–f/4 |
| Focus | Manual, ∞ | Manual, ∞ | Manual, ∞ |
| White Balance | 3500–4500K | 3500–4500K | 3500–4500K |
| File Format | RAW | RAW | RAW |
Key principle: Aurora intensity varies enormously — from a faint green smear to explosive curtains that fill the sky in seconds. Always shoot RAW so you can recover exposure in post-processing. Start at ISO 1600, f/2.8, 15 seconds, evaluate the histogram, and adjust from there. The 500 Rule (500 ÷ focal length = max seconds before stars trail) applies if you want pin-sharp stars — but aurora-only shots can use longer exposures since the aurora itself blurs under the shutter.
Smartphone users
Modern phones (iPhone 15 Pro, Pixel 8, Samsung S24) can photograph auroras in Pro Night Mode. Use a tripod, 5–30 second exposure, ISO 800–1600. Results are surprisingly competitive for KP5+ storms.
DSLR / Mirrorless users
Full manual mode, RAW files, and a wide fast prime lens (14–24mm, f/1.8–f/2.8) give you the best results and the most control. Mirrorless bodies have an edge in high-ISO performance due to newer BSI sensors.
Why 2026 is special
Solar Cycle 25 is near or at maximum. Auroras appeared as far south as Texas and Spain in spring 2024. Frequency of KP5+ storms is highest in 11 years — if you've wanted to photograph the aurora, 2026 is the best year in a decade.
