In the 1960s and ’70s, light became a primary medium for a loosely-affiliated group of artists working in Los Angeles. Whether by directing the flow of natural light, embedding artificial light within objects or architecture, or by playing with light through the use of transparent, translucent or reflective materials, these artists each made the visitor’s experience of light and other sensory phenomena under specific conditions the focus of their work. Key examples of this approach include immersive environments by Bruce Nauman and Eric Orr, each of which produce different and extreme retinal responses; the disorienting and otherworldly glow of a Doug Wheeler light environment; a richly hued and spatially perplexing light piece from James Turrell’s Wedgework series, and the subtle sculpting of space with natural light by Robert Irwin.
