"It’s like a Rubik’s Cube in real time in my brain." That’s how photographer Stephen Wilkes describes the way he shoots the 1200 to 1500 individual images he starts with to make one of his composites. Those thousands of exposures are eventually whittled down and edited into the 50 or so that appear in one of the "day to night" photographs he’s known for. Wilkes creates several exposures that show a subject—often a cityscape or other public place, like Chicago’s Wrigley Field pictured here—as it transitions from sunrise to sunset, including everything in between. TIME magazine recently published a great photo essay highlighting Wilkes and his work, and the story is online, along with his photographs, via the link below.
