Two Frames

In the painting [Two Frames], two types of straight lines overlap and interfere with each other, making them seem as if they were curved lines. The curved lines, created by the red and green straight lines, are the results of a particular optical illusion known as the ‘moiré effect’. For the red and green used in the painting, Chang took inspiration from how the human eye’s cone cells recognize three colors of L, M, and S; two of these are red (L) and green (M). The world looks flat when seen through one eye, and becomes three-dimensional only when both eyes are used. This three-dimensionality is created as two flat images from each eye interact with one another, and Chang commented that ‘people observe objects with a set of two unique eyes (the frame), and the interaction of colors creates the objects.’


Cheolwon Chang has been mesmerized by the act of seeing the world through a window frame, and the light that enters it. Every morning, light coming through the window creates a geometric shadow, and this inspired the artist to work with frames. A frame is a window to the outside, and at the same time, it is a boundary that separates the inside and the outside. Chang divided a paper into shapes based on the ratio of 1:1.414 and cut holes accordingly. He then installed the paper under sunlight, simultaneously showing the frame and the nature of time shown by the light that passes through the frame.
