During our last Polar Bear safari in the Churchill area, I had a fantastic opportunity to photograph the Aurora Borealis or Northern lights in the Canadian sky. The green lights are born from charged particles of the solar wind colliding with our atmosphere. The results are breathtaking for countries around the Arctic circle. Contrarily to what some people think, one can admire the Northern lights all year round and not just during Winter. All it takes is a clear night!
The photograph below is a panorama of an Aurora Borealis:
I was quite happy at my first try at creating a Northern lights photograph. In retrospective, I should have dialed in f/4 instead of f/7.1 to allow for more lights and a bit less noise. Note that the surface blur filter from Photoshop did quite a nice job at eliminating noise… The Aurora Borealis does not last all night long, sometimes just a few minutes in the middle of the night!
The creation above is a vertical capture. The Northern lights are not very static and move in a cloud motion in the sky. One moment, you see them in full and the other they start to slowly vanish. I wish I had had more chances at this exercise! Next time…
