Gianfranco Gorgoni, whose photographs of artists and their works blossomed into art themselves, and who documented the creation of some of the world’s best-known outdoor installations, died on Sept. 11 at his home in Harlem. He was 77 .

His daughter, Maya Gorgoni, said the cause was cancer.

Mr. Gorgoni photographed Andy Warhol lounging in bed and posing with a dog. He photographed Bruce Nauman as he created a work called “Corridor Installation With Mirror” at San Jose State College in California in 1970. Operating in photojournalist mode, he captured images of noteworthy figures like Fidel Castro and Truman Capote.

But he was best known for images of the genre often labeled Land Art — pieces created in a specific landscape, often only temporarily or, if not, destined to be ravaged by the passage of time. His pictures of “Spiral Jetty,” the 1,500-foot-long earthen coil that Robert Smithson made in the Great Salt Lake in Utah in 1970, portrayed that work at its creation as well as in subsequent years, as nature had its way with the piece, including submerging it entirely for almost three decades.
