Handmade paper made by boiling wood, pounding it, separating the fibers, and drying it. I hang it in the middle of the room. Paper illuminated by a halogen lamp casts a shadow. If you scan this shadow with an Instagram filter, it will start radiating. A shadow physically means that no light is reflected. However, when we perceive a shadow, it appears as if there is an object called a “shadow”. In the sense of perception, shadows may also be luminescent.
