Lie: “This is my newest work which follows a young Chinese climber on his 2 months expedition to various crags in Western US. The major goal of his trip was the first hard sports route in the States, To Bolt Or Not To Be 5.14a, at Smith Rock, Oregon. Will he fulfill his dreams? I hope you would enjoy his story.  https://vimeo.com/159240179”

Antosh: “I thought you might be interested in a 4K Aurora Borealis time-lapse I made, shot on a Panasonic GH4 near Karigasniemi, Finland. We were very lucky to see 2 spectacular geomagnetic storms in one week. Our guide warned us to keep cameras covered between shots, but shooting time-lapse I didn’t have that option. The GH4 just kept on going for hours at -25C! Condensation formed on it when I brought it indoors, but it’s still working fine :) https://www.youtube.com/watch?v=mIE0mYkIPQo“
