This labour of love took Chad and Linnea Blakley three years to create. What started out as a summer job in Abisko National Park, Sweden quickly turned into an obsession, and Chad found employment at the park’s Aurora Sky Station. Hunting for the phenomenal light display became his day (and night) job.

His time-lapse video of the swirling aurorae over the Swedish skies is composed from 2,000 hours of footage and is free from any type of colour correction. Have a look at the Lights Over Lapland below.
