Starting in August 2020, Sun Choi exhibited a series of works called Corona Camouflage. According to the artist, the work consists in combining a personally conceived symbolic image standing for the current pandemic with that for his memories from his time in high school recalled by the present situation of COVID-19. The image is combined and applied to various media such as a white canvas, white slicker, white cloth, his car and a plastic sheet. This process is called “visualization of atmosphere” by the artist. This term designates his transition from his experience of a particular atmosphere, or what this article will call “aesthetic experience,” to its concrete expression through practice. As he asks himself, “Is it possible to make a painting that allows the viewers to recall the COVID-19 situation of 2020?” His deliberated response is negative, having accepted the irreducible gap of understanding with the viewer. The cause for this gap of understanding is visibly sought out in his various experiments. This article will attempt to delve into Choi’s oeuvre to understand why, despite the above limits, he “came to think about the feelings of isolation, fear and disgust, as if in wartime, caused by disrupted everyday life, and about how to visualize them.” In attempting to provide the answer, this article will first clarify how Choi’s position regarding subjective sensibility and atmosphere, then refer to cognitive psychological and neuroscientific explanations of the aesthetic experience of the atmosphere of the pandemic, which will provide concrete grounds for his intention, thought process and method.
