One of the most beautiful cities in the world and the third populous city in the United States, Chicago, has its pride in being an alpha global city and a vital node in the global economic system. And, the diversified cultures and population make Chicago a unique stand among the global cities. It is one of the most popular cities that many photographers want to visit. Although Chicago skyline has been taken by many photographers but this classical shot of Chicago skyline at night has unique perspective for its own. Purple color has been used to imply royalty, prosperity, nobility, luxury and ambition. I took this classical shot of Chicago skyline at night and purposely use purple white balance to show these characteristics of city.
