During the 1960s, Ralph Gibson worked as an assistant first to photographer Dorothea Lange and later to filmmaker and photographer Robert Frank. In the early 1970s, along with his colleagues Diane Arbus and Garry Winogrand, he became a prominent member of the New York photographic scene. With the publication of his "Black Trilogy" of books, The Somnambulist, Deja Vu, and Days at Sea, Gibson gained a reputation as a pioneer of the photo-sequence---the creation of a series of images that together convey a story or idea. He developed a signature high-contrast, black-and-white style that used photography in a metaphoric manner rather than as a documentary tool.
