For 6 years, photographer Peter Tsai has been documenting the skyline of the city he lives in Chicago. Through his series called Cloud Chicago, he captures skyscrapers drowned by a dense fog and white clouds, at night and day. To get this height and these different perspectives, he accessed to the Hancock Observatory and the Willis Tower Skydeck.
