How To Capture Northern Lights With Camera
Professional aurora photography isn’t just about camera settings; it’s about Atmospheric Physics.
Your settings must change based on the speed of the solar wind and the clarity of the air.
- Fast Aurora: Needs fast shutter (2-5s) or it blurs.
- High Humidity: Needs lens heaters or careful checking for fog.
- High Clouds: Diffuse the stars, requiring sharper focus checks.
Below is the Aurora Photographer’s Cockpit. It pulls live data from 4 separate weather and space APIs to calculate the exact constraints you are shooting under right now.

Deep Dive: The Data Points
1. Aurora Speed vs. Shutter Speed
Our cockpit analyzes the Solar Wind Speed (km/s). If this number is high (>600 km/s), the aurora curtains are moving rapidly. If you use a standard 15-second exposure, those beautiful curtains will turn into a green smear. The cockpit calculates the “Max Shutter” to freeze that motion.
2. The Dew Point Spread (Lens Safety)
Look at the “Lens Safety” metric above. This calculates the difference between the Air Temperature and the Dew Point. If this number is small (<2°C), moisture will condense on your cold front lens element within minutes. Pro Tip: If the alert is flashing, keep hand warmers attached to your lens barrel.
3. Magnetic Power (Bz)
The “Bz” value tells us the brightness intensity. A negative number means bright aurora. If the number is positive (North), the aurora will be faint. The cockpit adjusts the recommended ISO automatically: High ISO (3200+) for faint aurora, Low ISO (800-1600) for bright storms to reduce noise.
