Andy Warhol’s camera work oscillated between the professional and the personal. He incorporated press photographs as source material for the creation of his paintings and prints, and utilized photobooths to create serial images of his subjects. Meanwhile, he used his Polaroid camera to create a visual diary of his life, long before the dawn of Instagram. “A picture means I know where I was every minute,” he said. “That’s why I take pictures.” This exhibition is one of only a few to focus on Warhol’s relationship with photography—so often overlooked in favor of the Pop art with which we associate him. The first was in 1987, a show at the Robert Miller Gallery that opened six weeks before the artist’s sudden death. —J.V.
