File:Kaliningrad, Baltic Sea, Russia.JPG
Summary
This photograph from the <a href="//commons.wikimedia.org/wiki/International_Space_Station" title="International Space Station">International Space Station</a> captures two great lagoons to the north and south of Kaliningrad, Russia. The dark blue features are land. The beige mass at the top and the beige mass in the lower right are the lagoons. The largest mass of beige is the Baltic Sea. From an astronaut’s perspective in low-Earth orbit, land <a href="//commons.wikimedia.org/wiki/Surfaces" title="Surfaces">surfaces</a> usually appear brighter than <a href="//commons.wikimedia.org/wiki/Water" title="Water">water</a>. But in this image, reflected <a href="//commons.wikimedia.org/wiki/Category:Sunlight" title="Category:Sunlight">sunlight</a>, or <a href="//commons.wikimedia.org/wiki/Category:Sunglint" title="Category:Sunglint">sunglint</a>, inverts this pattern. The light has a coppery <a href="//commons.wikimedia.org/wiki/Category:Hue" title="Category:Hue">hue</a>, perhaps due to <a href="//commons.wikimedia.org/wiki/Category:Smog" title="Category:Smog">smog</a> particles in the air, which enhance the <a href="//commons.wikimedia.org/wiki/Red" class="mw-redirect" title="Red">red</a> part of the <a href="//commons.wikimedia.org/wiki/Spectrum" title="Spectrum">spectrum</a>.
The <a href="//commons.wikimedia.org/wiki/Camera" title="Camera">camera</a> settings used to acquire sunlint images result in high <a href="//commons.wikimedia.org/wiki/Category:Contrast" title="Category:Contrast">contrast</a>, which reveals the fine detail of coastlines and surface features of water bodies, while masking land surface details. The thin, 50 kilometre barge canal leading from the Baltic to Kaliningrad is visible, but the great port of Kaliningrad itself is not. Other <a href="//commons.wikimedia.org/wiki/Homo_sapiens" title="Homo sapiens">human</a> patterns on this intensively developed landscape—such as towns, highways and farm boundaries—are likewise masked.
The area has a long human <a href="//commons.wikimedia.org/wiki/Category:History" title="Category:History">history</a>. The growth of the <a href="//commons.wikimedia.org/wiki/Vistula" title="Vistula">Vistula</a> spit finally cut off the north Polish city of <a href="//commons.wikimedia.org/wiki/Elbl%C4%85g" title="Elbląg">Elblag</a> (just beyond the bottom of the image) from the <a href="//commons.wikimedia.org/wiki/Baltic_Sea" title="Baltic Sea">Baltic Sea</a> in the <a href="//commons.wikimedia.org/wiki/Category:13th_century" title="Category:13th century">13th century</a>.
