James Turrell
James Turrell has innovated photographic techniques that allow light to have a physical presence. Turrell creates colored light installations that appear to possess mass and take up space as planes, cubes, pyramids, and tunnels. Using holography, he makes light itself the subject rather than the medium. Turrell’s series “Skyspace” (begun in the 1970s) are enclosed spaces open to the sky through an aperture in the roof that enables viewers to observe changes in light from minute to minute and season to season. The work has been described as a religious experience.
