This is selection of northern lights Flat Light Films (http://www.flatlightfilms.com/) filmed during the winter 2011 in several locations in the Finnish Lapland. It’s filmed with DSLR cameras with time-lapse technique and with remote pan/tilt heads. Absolutely amazing.
The Northern Lights, Aurora Borealis, is a light phenomenon that occurs in the Arctic sky on clear, dark nights, caused by solar winds interacting with the earth’s magnetic field. The deep green and yellow colors, sometimes streaked with bands of red, are one of the most astonishing natural phenomena one can witness. They can be seen from September to April, but unfortunately their occurrence cannot be reliably predicted.
