After a long hike from his small cabin to Kvalvika, Lofoten Islands, in Norway, Nicolas Alexander Otto arrived at the slopes above the beach at about midnight.
During the hike, the aurora borealis display was relatively weak. But when he made it to the beach, the sky ignited in a colourful show of greens and purples framed by the mossy landscape.
The image was composed from six different exposures due to the high ISO camera setting and thermal noise in the foreground. The sky was added from one of these exposures.
