As an avid photographer who loves shooting the aurora borealis (more commonly known in the northern hemisphere as the northern lights), I sometimes get asked for tips. Being in southwestern Ontario, I don’t have the advantage that many high-latitude sky watchers have, so when the northern lights are out, I want to make the most of it! Here’s a summary of everything I’ve learned since I started shooting them back in 2001.
THE BEST TIME TO SEE THEM
As solar wind hits Earth, northern lights are formed. Northern lights are always occurring, but depending on location, daylight, cloudiness, moonlight conditions, etc., you might not actually see them. Midnight is usually the best time to see them, but that’s not always the case. Here are two factors that can affect when the northern lights get brighter:
- Magnetic Field Fluctuation: Sometimes Earth’s magnetic fields fluctuate in power. When they do, they can create “open doors” to let solar wind through more openly. It’s not very well understood, but in and around equinoxes (March 20 and September 23 in 2015), the chances to see the northern lights increase substantially.
- CME’s (Coronal Mass Ejections): CME’s (explosions on the sun) send mass amounts of electromagnetic radiation into space. When one of these explosions is directed toward Earth, it causes a geomagnetic storm, sparking auroras. On rare occasions when a powerful CME hits Earth AND the magnetic field is weakened, northern lights can be seen as far as Texas and even closer to the equator.
INCREASE YOUR ODDS OF SEEING THE LIGHTS
Photographers don’t just end up being in the middle of nowhere in the wee hours of the night. Here are five essential tools that I use to determine when the northern lights are going to hit.
- I get email alerts about 30 minutes in advance from AuroraWatch. If you're south of Toronto (about 43.7°N), only ask for the Red Alerts. You won't see anything less. (Note: If you'd like to get a little more serious and pay for SMS alerts, SpaceWeather.com has a great service as well.)
- I watch the real-time Aurora map from the National Oceanic and Atmospheric Administration (NOAA). If you're above the red view line, there's a good chance you'll see them.
- I monitor the 3-hour Planetary K-index from NOAA. If it's above 6.3K AND it's past dark AND it's clear outside, there's a good chance you will see the northern lights.
- Aurora Forecast also offers a helpful iPhone app.
- I follow the Facebook feed from Aurora Alerts by Soft Serve News. They provide updates every 30 minutes as well (as to what the next 30 minutes be). Again, watch for 6.3K or higher. If you see something magical over 8.0K, get the kids out of bed and go for a drive.
One huge caveat to all of this is weather and moonlight conditions. If it’s completely overcast outside, ignore all of your alerts—you won’t be able to see the northern lights. Additionally, if you find yourself in a lunar cycle where the moon is full (or close to it), viewing the lights may be severely obstructed.
WHERE TO GO
Simply put, go where it’s dark. When I receive an alert (and I’m not sound asleep), I drive as far away from the city as I can. For high-latitude residents, this isn’t as much of an issue as sometimes the lights can literally be on top of you, but for people like me (who live further south), you’ll want to get as remote as possible. Generally speaking, look north, but that’s not always the case. Solar wind can fluctuate at the drop of a dime so pay attention to east, west and right above you.
One tip that’s often overlooked: try and pick an interesting spot beforehand. Drive around during daylight hours and look for interesting trees, farmhouses, etc. that would make a good foreground for the lights. If you’re thinking about walking into a field, make a visual note of obstacles, holes, etc. Then, go back at night (on a non-northern lights night) to see if your intuitions were correct (i.e. there is no major light pollution, no angry barking farm dogs, etc.). Pictures with good foreground subjects (i.e. buildings, trees, water reflections, mountains, very still people, etc.) are always more interesting than shooting into a flat field.
HOW TO SHOOT THEM
Every person’s gear is going to be different, but there are some common tips that I believe can prove valuable to everyone:
I know it sounds silly, but you’d be surprised at the number of people who run out to shoot the northern lights in the winter without a jacket. Plan accordingly! Pack warm clothes and make sure you have everything you need (charged batteries, cables, lenses, coffee, more coffee, etc.). It would be a shame to get out there, just to realize you missed capturing the best light show of your life because you weren’t prepared. (Also, use the restroom beforehand.)
- Provide stability
Shoot with a tripod, and if possible a remote shutter release. If you lack a remote shutter release, a quick trick that I’ve found is to set your camera timer (to ~2 seconds). That way you can press the shutter release button and move your hand away from the camera (thereby not causing it to jiggle).
- Choose the right settings
The key to capturing the northern lights is long-exposures. Essentially, you are letting light build on your camera sensor. Settings are critical. My general rules are as follows:
Shoot as low an ISO as possible (ideally 100 — 400 ISO)
Shoot as low an aperture as possible (ideally f/2.8 — f/4.0)
Keep your shutter speed between 6-12 seconds.
You will have to adjust according to light conditions. If the auroras are brighter, you will be able to get away with a lower ISO. If they are weaker, you may have to increase your ISO to 800. In my experience, anything higher than 800 and you’re going to start getting “fake stars” due to camera sensor noise, especially if you end up printing a larger version of the photo. The lower the shutter speed, the more you are going to see the lights dance in your photos (i.e. 8 second exposure). The higher the shutter speed, you will see more of a northern lights blur (i.e. 15-30 seconds). Note: Sometimes the blur effect can be cool as well and is the only viable option in a weakened geomagnetic storm. The following image is a good example of that.
If the lights were powerful, I’d aim for the following settings:
100 - 400 ISO
6-8 second exposure
f/2.8 - 4.0
If the lights were weak, I’d aim for the following settings:
400 - 800 ISO
8-16 second exposure
f/2.8 - 4.0
If your lens isn’t capable of shooting as low as f/2.8, you may have to increase your ISO or exposure time to compensate for light.
Another thing you’ll want to consider is what format to shoot in. Personally, I like to shoot in RAW format so that I can process the photos later. Others prefer to shoot in JPEG format, which essentially means that your camera processes the photo for you. RAW format files give you more flexibility with tones, shadows, exposure, white balance, etc. As far as camera bodies go, let me just say this: As it relates to shooting northern lights, your lens is far more important than your camera body. A low-priced Canon EOS Rebel or Nikon D3300 will take a phenomenal northern lights photo with the right lens and settings. My personal setup when shooting the northern lights is as follows:
- Get focused
When you’re standing on a dirt road and it’s pitch black, one thing you’ll realize is that it’s tough to find focus. The last thing you’ll want to do is take a bunch of amazing pictures, just to get home and find out that they’re all blurry. So how do you find focus in the dark? I’ve often heard photographers say to set your lens to infinity focus, which is sort of true, but even that isn’t perfect (as many lenses don’t have accurate line markers for what infinity actually is). The best way I’ve found is to locate a bright star in the sky (or a light on a farmhouse… or a light on a cell tower) and focus on that. Once my camera grabs focus, I immediately switch the lens from auto-focus to manual focus. I don’t touch the lens again for the rest of the night (unless I feel that I’ve jarred it when I switch locations). Another (smarter) way to do this would be to find focus on a far off object in the daylight before your trip. Then switch to MF and don’t touch it.
After you’ve shot all your pictures, you’ll want to consider post-processing. If you were to talk with most professional photographers, this is the critical distinction between a good photo and a professional photo. Post-processing offers you the ability to make critical adjustments (i.e. brightness, contrast, white balance, etc.) to your photos. Personally, I use Adobe Lightroom. It’s worth its weight in gold.
- Have fun
Part of the experience in northern lights hunting is the adventure: the journey down dirt roads, hiking into a field, sharing the time with friends, etc. Don’t forget to realize the amazing thing that’s happening right in front of you. Take it in and enjoy it!
