Chromakey Doorway 1994. Mixed media installation with video, live camera and chromakey unit.

A false door is set into a wall of the exhibition space. Sound can be heard coming from behind the door and a notice on the wall next to it reads 'Exhibition continues this way'. Opposite the door is a video camera on a tripod and the image from the camera is streamed live to a video monitor.

When the door is opened, rather than another room, the viewer is met with a solid surface of chromakey blue paint within the door frame. On the adjacent video monitor, this blue surface is now occupied by a superimposed video, keyed into the area of blue. After the surprise of there being no other room beyond the door, the viewer is then confronted with the paradox of seeing a different image on the video monitor than in reality.

The background video which intrudes into the scene is a reconstruction of a visual hallucination experienced by the artist in Hamburg several months earlier, when inside one of James Turrell's perceptual cells. The superimposed video is a vertiginous, rising and falling view of a cityscape with ant-like figures bustling about, whilst fluorescent coloured plastic cutlery floats across the scene. The superimposed video can only be seen on the monitor when the door is opened.
