After Diane Arbus committed suicide, in 1971, the Arbus Estate authorized one person to print from her negatives, the British-born photographer Neil Selkirk. “She was someone who to her core was absolutely enthralled to know what made people tick,” Selkirk said recently. “That was her thing.” Arbus brought the same level of fascination and concentration to all kinds of people—from children to nudists, suburban families to drag artists—capturing them in compelling black-and-white portraits. In 2007, the Metropolitan Museum of Art acquired Arbus’s archive; and in 2011, a complete set of 454 printing proofs was purchased by the Swiss heiress and art patron Maja Hoffman. To mark the centenary of Arbus’s birth, that set comprises this exhibition at Luma Arles. Curated by Matthieu Humery, the immersive installation positions all 454 photographs on metal scaffolding, offering visitors a rectilinear web—or “constellation”—of Arbus images. —Paulina Prosnitz
