Born in the Netherlands (1957) and living and working in Amsterdam, Roos Theuws devotes her work to an indept inquiry into what video is, can do and effectuates in the field between machine and viewer. From the beginning, she has shown an interest in the phenomena of light. In her recent works, the use of light has become an aliquid between the viewer and the presented piece. The light can be treated in almost agressive, violent, manipulative manner, hurting the eye. In other pieces, together with the filmic, emotional contents, light functions as a soothing bath. As a result, video becomes the field of interrogation, providing the artist with a wide variety of visual manipulative devices, reaching out for meanings beyond rational perception and observation.
