The photo above showing a stunning curtain of cirrus clouds over Paris, France, was captured on June 19, 2016. Thanks to a high-pressure system positioned over western Europe, Sunday the 19th was a pleasant late spring day in the City of Light; mostly sunny skies, mild temperatures and calm winds. As the Sun set, wavy cirrus clouds graced the twilight sky. These clouds, visible during the late afternoon, were particularly pronounced after sundown. Note that because the Sun is more than about 10 degrees below the horizon, even these high altitude clouds are too low to reflect sunlight.

Photo Details: Camera Model: Canon EOS 7D; sigma lens; Focal Length: 28mm; Aperture: ƒ/9.0; Exposure Time: 8.000 s; ISO equiv: 100; Software: Adobe Photoshop CC 2015 (Windows).
