In Dec. 2010, the artist ZHANG Xiaogang finished his important exhibition “16:9” in Today Art Museum. The exhibition showed an installation and some latest created paintings. Through these artworks, the artist continued his review of the historical memories and expressed his inner emotions. Today Digital Art Museum made a 1:1 digital record of this exhibition and intended to launch a digitalized exhibition of ZHANG Xiaogang with the same title “16:9”. All kinds of details such as the original positioning of the works, the sizes, the arrangements and even the light and shade were recorded completely. When the audiences were in the digital space, they could hardly distinguish between the real and virtual.
