"Burning Oil Sludge, Boulder County, Colorado" (1974)

"Light is a physical thing that you’re working with. It’s also obviously metaphor. It’s what you’re working with to arrive at metaphors. It’s the age-old symbol for truth. So it’s loaded. But, fundamentally, it’s just a deeply mysterious, compelling ingredient for your understanding of life and your response to it....It’s at the center of why and how one makes pictures."
