Distanceis a triple-frequency video. It is displayed in the Korea Factory Art Festival in 2014.

　　The object of the video is the work lamp whick is my companion all year. On the Mid-autumn Festival, it appeared in my camera as the full moon. Actually the moon-like object was only 21.3cm to the camera;it appeared as a full frame of light when being shot at zero distance; only from the distance of 99.1cm, it took on the look familiar to us. But as the color temperature became colder at the moment, our naked eyes would never consider it as the same object as the other two.

　　This work represents the “investigation” of the “truth” of objects and our doubt about our customary perception.
