How to photograph an aurora
This is a brilliant article by Loic Le Guilly posted on https://digital-photography-school.com/how-i-captured-my-first-aurora-australis/
“My friend started shooting and the results on the camera screen were pretty exciting. The camera sensor and a long exposure reveal a lot more light and colour that can be seen by the naked eye. He kindly offered me to shoot a few frames. I decided to go for it with a 30 second exposure at 3200 iso, 16mm rectilinear lens wide open at f2.8. This can be too bright for really active auroras but I wanted to capture as much of the Milky Way as possible. The first shot I took is the one you see below (straight out of the camera). When I checked the image on the camera the green of the aurora looked very bright but I knew it wasn’t completely overexposed. But the upper red glow was recorded very nicely. Some low drifting clouds added a nice movement to the shot.
Post processing in Lightroom
I was very excited by the shot I got but I knew I could improve it in Lightroom (I had shot in raw format as I always do). This is a what I did :
- crop and straighten
- white balance – In my experience long exposures introduce a yellow tinge to night photographs. I took the white balance from daylight (5500K) to 3750K.
- exposure – I reduced the overall exposure by half a stop. I also applied another -1 stop to the green part of the aurora (with the adjustment brush).
- contrast – Long exposures at night tend to give flat images. I increased the overall contrast of the image (blacks to 19, contrast to 74, curve to medium contrast). I also pushed the local contrast (clarity to 100). That setting alone revealed the “curtain” of the aurora really well. Finally I increased the contrast further to the top third of the image to darken the sky.
And this is the final result.
And here is another image made from 2 shots stitched together in PTGUI. This one was 20 seconds at 3200 iso.
Not bad for a first night with an aurora.
How to know when an aurora might be coming ?
Final tips for photographing an aurora australis
- a clear night
- a spot looking south and ideally away from city lights (to avoid light pollution and flare)
- a tripod + camera + wide angle lens (ideally f2.8 or faster)
- use a remote trigger with mirror lock to reduce camera shake (if no remote than use timer on camera)
- ideally shoot in raw format for better quality
- noise reduction off (if shooting raw) to save time
- manual focus to infinity (test on a clear night before hand to avoid disappointment)
- iso 1600 to 3200 (or more if your camera can handle)
- exposure 10 to 30 seconds (longer exposures will start to show stars as trails rather than dots)
- these settings will depend on the brightness of the aurora so experiment, adjust and shoot lots of images !
Photographing an aurora is a truly exciting experience. I have read that 2013 should be a good year for auroras so keep an eye out and be ready !”
