Yoon Suk One treats painting as a medium for documenting his unique observation and contemplation. Yoon constructs a fundamental resource of his practice by collecting and taking pictures of city landscapes constantly shifting their appearances depending on the change of light and seasons. The viewers can notice the vertical or horizontal repetitive brushstrokes on the top surface of his paintings. Being mainly discovered in the edge of each image which is evenly spread over the surface, this pattern is achieved by brush movements of pressing the surface and pushing it in both directions. This approach decreases the level of identifying outlines of the images while evoking a tone down effect and regional dynamics. Moreover, the oscillation sometimes decides the tonality of each work, as it evenly appears on the entire surface.
