HDR City Skylines

A skyline is best described as the overall or partial view of a city's tall buildings and structures consisting of many skyscrapers in front of the sky in the background. It can also be described as the artificial horizon that a city's overall structure creates. Skylines serve as a kind of fingerprint of a city, as no two skylines are alike. For this reason news and sports programs, television shows, and movies often display the skyline of a city to set location. The Sky Line of New York City was a new term in 1896, when it was the title of a color lithograph by Charles Graham for the color supplement of the New-York Journal.
Paul D. Spreiregen, FAIA, has called a skyline "a physical representation facts of life ... a potential work of art ... its collective vista."
In general, larger cities have broader and taller skylines, though lower density cities often have smaller skylines than expected for city size. Taller buildings are found where either land value or desire for visibility is higher, and the tallest buildings in a city are usually office buildings. Because of this, the skyline of a city can be seen as symbolic of the city's influence and economy.
