Ever think much about Contrails?
Air travel is great, but it often pains photographers day and night. During long exposures at night you’ll often see plane lights streaking across a dark sky and during the day you’ll frequently see contrails polluting the sky. On a trip to Yosemite last summer it became painfully evident how bad contrail pollution is, while taking in the scenery at the Tunnel View lookout. I counted 8 contrails in the sky above Yosemite valley at sunset. I find it interesting that the National Parks and Wildlife Refuges protect that which is on the ground but by and large ignores the air above it. Is protected land any worse for the wear because plane traffic can fly 10,000 or 30,000 feet above? I tend lean toward the land being worse off. Sadly most people don’t notice how much air travel flies overhead, because few sit still long enough to notice. Leave a camera in place for a time-lapse or a long exposure and you’ll quickly see how much of our sky is polluted by air travel.
