We’ve probably all got different things we’d like to photograph in the Arctic but for most of us the Aurora Borealis is going to be high on our list.
The Aurora is caused by charged particles from the sun colliding with the Earth’s magnetic field. It varies with solar activity and it’s visibility is dependent on cloud a light pollution from towns and cities. there is no guarantee that you will see it in the Arctic but the longer hours of darkness in the winter and the Northerly aspect of the sky does increase your chances somewhat.
The next trick is to actually record what you are seeing with a camera.
In most cases it will require a long exposure a tripod or other firm support for your camera. It’s very easy to be fooled by the display on the back of your camera when your eyes are adapted to darkness. A quick glance at the screen will convince you that you have the most amazing pictures on your card but unless you are lucky, disappointment lies that way.
More often than not you will find the image is underexposed and very noisy as a result. (This rates as my most regretted mistake in 40 years of photography and one that I hope will never repeat.) It is far better to check your exposure using the histogram function on your camera. (Check the instruction book if you are not already familiar with that feature.)
