In her memoir Hold Still, photographer Sally Mann wrote of the “tinge of sorrow” that permeates life in Lexington, Virginia, the sleepy Southern town where Mann created her most iconic images and where she and the artist Cy Twombly were friends and confidants for more than 20 years. Here Mann writes intimately of her relationship with Twombly and the photographs she made of his studio before his death in 2011, now on view at Gagosian Gallery in New York in the exhibition Remembered Light.
