The Aurora Borealis is also called the Northern Lights. The Northern lights are some of the prettiest things Mother Nature has to offer. But there is a price...It's cold and you have to catch them late at night. Northern Light come in red, yellow, blue, and the most common green. The Lights are caused by a solar flare on the sun that send electrons that bounce off the atmosphere, creating a light.. Tips for photographing the Northern Lights: Use 100 or 400 speed film (sounds funny, I know) but higher film becomes very grainy. Leave the shutter open for several seconds. I use 30 seconds unless there is a full moon, then I used 15 to 20 seconds. Experiment! Keep extra batteries in your pockets where they are warm, the cold will kill batteries quick. Dress warmly, and stay away from city lights if possible. Search the internet for other tips on Photographing Northern Lights.
