Adams' autobiography was published posthumously in 1985, one year after his death. In it, he reflected on his 1968 photograph of El Capitan and his collaboration with Edwin H. Land: "Many of my most successful photographs from the 1950s onward," he wrote, "have been made on Polaroid film…. One look at the tonal quality of the print I achieved should convince the uninitiated of the truly superior quality of Polaroid film."
