Contact sheets may be a relic of film photography, but they’re worth a close look for all they reveal about the photographic process — which, as The Contact Sheet shows, is often as bewitching as the final product. In the book, you’ll learn the back stories to some of the most iconic images, too. Like whom Peggy Moffitt was channeling while she modeled Rudi Gernreich’s infamous topless monikini. And the children’s tale that partially inspired Chuck Close’s first self-portrait. And whether Robert Doisneau’s legendary shot in Life of a couple kissing in post-war Paris was, well, spontaneous. P.S.: It’s Babe Paley, Gulliver’s Travels and no.
