Shooting an aurora from France is not the same as shooting one in Norway. Pulsar notifies you the moment an aurora becomes visible from your city - the next challenge is capturing it cleanly. And conditions are more demanding: lower aurora on the horizon, weaker intensity, and often more red than green. Here's a method adapted to French territory, from the modern smartphone to the mirrorless body.
The smartphone has become a great tool
In 2026, recent flagship smartphones (iPhone 12 Pro and up, Pixel 6 and up, Samsung S21 and up) include a night mode combining long exposure, multi-image stacking, and software denoising. They can now capture a faint aurora that the eye doesn't see - that's exactly what allowed many French observers to "discover" the May 2024 aurora by simply taking a test photo.
Phone procedure: enable night mode (moon icon or dedicated button), rest the phone on a stable surface (wall, car, €10 mini-tripod), point at the northern horizon, start exposure. Optimal duration 5 to 10 seconds. Check the image: if a colour - green on bright phases, red/violet on extreme phases - appears while you see "grey" with the eye, it's confirmed.
Settings for mirrorless or DSLR
If you have a camera with manual focus and M mode, here's the reference configuration to adapt to aurora intensity:
- Aperture: widest possible (f/1.4 to f/2.8). The faster the lens, the better.
- ISO: 1600 to 3200 on a modern APS-C or full-frame sensor. Push to 6400 on faint phases, but noise becomes obvious.
- Shutter speed: 5 to 10 seconds for static phases, 2 to 4 seconds when the aurora "dances" (longer blurs the structures).
- Focus: manual, on infinity. Pre-set it in daylight on a distant target and gaffer-tape the ring so it can't drift in the dark.
- White balance: 3,800 K (equivalent to "Tungsten" or "Incandescent") - gives more saturated aurora greens than Auto.
- Format: RAW, mandatory. Post-processing recovers 1-2 stops on highlights and shadows.
Lens choice
Aurora over France is rarely compact: it spreads as horizontal bands across the whole northern horizon. A wide-angle from 14 to 24 mm (full-frame equivalent) is ideal to capture the full phenomenon and include foreground (forest, mountain, water). Constant f/2.8 zooms (Sigma 14-24 f/2.8, Tamron 17-28 f/2.8, Sony 16-35 f/2.8) are excellent generalists.
Reserve longer focal lengths (50 mm, 85 mm) for cases where you want a specific structure (auroral corona, distinct vertical columns). These are rare in France, except in extreme events like May 2024.
Essential accessories
- Stable tripod: for 4-second exposures, any entry-level tripod is fine. Beyond 10 seconds, step up.
- Remote release or 2 s self-timer: eliminates trigger micro-blur.
- Spare batteries: cold halves to thirds their capacity. Keep them inside your jacket.
- Red headlamp: preserves your dark-adapted vision (15-25 minutes to rebuild otherwise).
- Gloves: swapping batteries bare-handed at -2°C gets old quickly.
Compose a real photo, not just evidence
Many aurora photos from France are "proof shots": a band of light above an empty horizon. Useful to confirm an observation, but not a real picture. To move from evidence to composition, add a foreground element: a lone tree, an animal silhouette, water reflecting the aurora, a mountain, a lighthouse. That element gives scale and geographic anchoring that turn the photo around.
Think composition too: rule of thirds, horizon in the lower third if the aurora is high, in the upper third if it's a low band. A shooting star or a Starlink train at trigger time is a notable visual bonus - particularly in the morning passage windows.
Minimal post-processing
In a photo editor: exposure +0.3 to +0.7 stop depending on underexposure, highlights -20 (recover saturated colours), shadows +30 (lift the foreground), clarity +10 to +20 (aurora structure), saturation +10 max - beyond that it gets cartoonish. Avoid aggressive denoising on bright phases - grain adds a realistic night feel. Push it on faint ISO 6400+ phases.
