Jeong's decision of capturing a physical phenomenon of light and shadow marks her artistic style and makes her outstanding in Korean contemporary art scene. In both Either far or close and Certain View, the location of the natural light can be predicted by measuring and observing the ways light rays flow in and affect the surface of the interior space. Beyond the scientific perspective of light, Jeong's works invite viewers to question the phenomenon of light that exists in her paintings and in our everyday life.
Using the versatile medium of oils, Jeong paints the ambiance light can create in any setting. In Certain View (Lot 428), the small decorative chandelier looks misplaced in the geometric interior of concrete walls and floors. In this industrial setting, someone purposefully made this place livable as did the tenant of Either far or close (Lot 429), with the iron chairs placed on a terrace that overlooks a rustic scene. Despite the harshness associated with industry and manufacturing, Jeong uses the natural warmth of the sun to illuminate both paintings, showing the potential for comfort and beauty in the starkest of environments. The light of the sun which peeks through the wispy clouds in Either far or close is painted with a photographic and delicate quality; one can practically identify the scientific name of the formations or sense an angelic presence. In a genuine situation, it would not be possible to find shadows formed on two opposite walls, suggesting a less scientific but greater depiction of the spiritual characteristic of light (Certain View). As the light and smoke seem to flood through the windows, the viewer can feel heavenly warmth
Painting with the technicality, precision and subject matter of natural lighting as the Old Masters did, Jeong revives landscape paintings by incorporating contemporary elements such as welded iron chairs, smoke stacks and concrete tiles. She subtly plays with the presence and effects of light on the viewer, creating a cheerful visual puzzle for the viewer to decipher as suggested by the ambiguous title of both works. The depiction of light in Jeong's works also shows her keen observation on the phenomenon of light, leading her to catch the stillness of light, exposing the spiritual quality it can hold over a space and viewer. The two folds of light, both internal and external, are revealed in Jeong Bo Young's paintings.
