Tom is back with another breathtaking time-lapse video in his landscape series Timescapes. Using high definition equipment, he’s “dedicated to pushing the artistic boundries of timelapse and outdoor cinematography, with a particular emphasis on night timelapse.” His latest was shot in California’s White Mountains and Yosemite. It’s definitely one to watch in full screen. This makes me recall a recent fascinating National Geographic article, “Our Vanishing Night” which bemoans how the progress of human development resulted in pervasive light pollution that has robbed us of our night sky without some consequences as a result.
Light pollution is largely the result of bad lighting design, which allows artificial light to shine outward and upward into the sky, where it’s not wanted, instead of focusing it downward, where it is. Ill-designed lighting washes out the darkness of night and radically alters the light levels—and light rhythms—to which many forms of life, including ourselves, have adapted. Wherever human light spills into the natural world, some aspect of life—migration, reproduction, feeding—is affected.
