The new Sweetgrass film Afterglow shows backcountry skiing in a whole new light. Literally.
Shot entirely at night in Alaska and British Columbia, it features skiers wearing special suits covered in dozens of tiny lights that paint a rainbow of colours across the epic snowscape.
"It's Like Nothing We've Ever Seen In A Ski Movie"
This incredible effect is added to with more light being projected on to the mountains, creating an other-worldly environment like nothing else we've seen in a ski movie.
We're assured that there's no post-production trickery going on here, it's just the light that the filmmakers threw around when filming.
It goes to show what can be achieved with a bit of imagination and a few light bulbs. But, before you go digging out the Christmas lights to start making your own version, remember: electricity and snow don't mix.
