Glowstick Trails in Night Waterfalls

Sean Lenz and Kristoffer Abildgaard created this stunning project, Neon Luminance. They  Cyalume glow sticks into several Northern Californian waterfalls and then took long exposure photos of the effect. The sticks, sealed up to prevent any leaks, floated down the fall and then were collected by the team, leaving no impact on the falls or their watersheds.
