On my recent trip to the sub-arctic to photograph/film Polar Bears and Beluga Whales, we had an opportunity to witness and capture some images of one of nature’s most spectacular and inspiring shows, the Aurora Borealis or otherwise known as the Northern Lights.
Each day after a long adventure of traveling across the tundra in search of Polar Bears, we would head back at sunset to grab a cold sandwich and beer, we would get about an hour and a half break before heading out for the night to capture images of the northern lights.
We would check several apps on our phones to see what the aurora forecast would look like and if we would have clear skies and light winds. Then we would decide upon what we wanted to use as a subject in the foreground of the picture. Images of the northern lights are good but having something in the foreground to give it some perspective is essential in my opinion. The first night we decided it would be spruce trees and a small rustic building.
We drove about 20 minutes to a spot that would accommodate both trees and a building. Along the way we could see the aurora outside the van windows, and everyone was getting excited. When we arrived, I quickly set up my tripod and small ball head which would allow me to position the camera either vertical or horizontal and make sure to hold the camera very still since the exposures needed are very long.
Once I picked out a spot with several nice tall and narrow spruce trees in the foreground, I needed to make the changes to the settings on the camera to be able to capture the images. For this I use a red-light head lamp to see the small knobs on the camera and make all the adjustments needed.
For most of these images I knew I needed at least a three and sometimes up to five second exposures. This is why a stable tripod is so important. The ISO, or sensitivity of the sensor, needed to be adjusted to be very high, around 3,200 or higher. Using extremely high ISO’s is something that I couldn’t do back in the film shooting days so it’s a welcome advancement in photography.
Setting the focus on the camera to infinity is the next important setting. You can’t go past infinity; it needs to sit right at the exact spot to make sure the image is sharp. Then it’s a matter of taking a picture and seeing how it looks on the display screen and tweaking the adjustments to your liking.
