Sunset to Sunrise over the Baltic Sea Image Credit & [3]Copyright: [4]Bernd Pröschold ([5]TWAN) Explanation: [6]This serene view from the coast of Sweden looks across the Baltic sea and compresses time, presenting the passage of one night in a single photograph. From sunset to sunrise, [7]moonlight illuminates the creative sea and skyscape. Fleeting clouds, fixed stars, and flowing [8]northern lights leave their traces in [9]planet Earth's sky. To construct the timelapse image, 3296 video frames were recorded on the night of June's Full Moon between 7:04pm and 6:35am local time. [10]As time progresses from left to right, a single column of pixels was taken from the corresponding individual frame and combined in sequence into a single digital image 3296 pixels wide.
