What is Hidden What is Seen is about visibility and perception, about darkness as the absence of brightness, and about the faint lights that flicker in the depths of winter. The works are divided into two floors of Oksasenkatu 11: upstairs, drawings and texts operate in the light, and downstairs, in the dark, light is radiating from the artworks themselves. What is Hidden What is Seen features video, drawing, text and installation.This is the second instalment of the collaboration between Lisa Him-Jensen and Henni Kitti, and a continuation of their first project and exhibition, Light in the Absence of Light.
