Long exposure neon waterfalls

Looking something like the Aurora Borealis taken to water, this is a collection of photos entitled Neon Luminance from between Sean Lenz and Kristoffer Abildgaard of From the Lenz. The team sent various colours of Cyalume glow sticks down a selection of waterfalls in Northern California and then captured long exposures (varying from 30 seconds to seven minutes) of the submerged trails of light as the sticks moved through the current. For the more complicated shots they strung several sticks together at once.

A note on pollution: The duo are environmentally conscious and the sticks were never opened during the exposures. They are bouyant and were easily located at the end of the exposure and all collected, leaving no toxins or plastic in the water at all.
