From National Geographic:
"Over the past year, Anna Possberg and her husband, Claus Possberg, have traveled four times to the Scandinavian Arctic to photograph the [auroras] phenomena, which appear as stunning light shows in many northern countries, especially during dark winters.
Claus is a radiologist who’s also an avid traveler and photographer, and Anna is a full-time professional filmmaker. The Arctic Lightscape project, which the couple funds independently, resulted in a time-lapse video: a series of still photographs stitched together into a video format and published on Vimeo last week."
The full article illustrates some of the challenges faced by the Possbergs and how they overcame obstacles such as freezing temperatures, less-than-ideal weather, and finding shelter.
