When we look at an image through a monitor, we sometimes realize that we are looking at a mass of pixels (or you are looking at the monitor itself). Similarly, in paintings, from a certain moment, the presence of the medium may precede the recognition of the iconography. In this case, the existence of light has the function of suppressing the consciousness of such vision and concentrating it on the image, but the existence of light is also not usually conscious. Therefore, we usually have no doubt about seeing.
Through his series of artworks, Keisuke Katsuki attempts the viewer to recognize the fundamental ambiguity of the sense of vision by controlling the existence of those unconscious things.
