In 1957 he settled in Rochester, New York, to study photographic printing with Minor White. He also wrote for Aperture magazine. That year he published Gestures of Infinity, which included his own poetry and images, and in 1960 he published Under the Sun with images by Chappell, Nathan Lyons, and Syl Labrot. With Paul Caponigto, Carl Chiarenza, and others, Chappell founded the Association of Heliographers. In the late 1960s, he moved to Big Sur, California, then Taos, New Mexico, and then San Francisco, where he lived until 1974. He experimented with new subjects and techniques including high voltage/high frequency electron imagery of plants. From 1977 through 1979 he worked in Hilo, Hawaii, as an artist-in-residence at the Volcano Arts Center. In 1977, 1980, and 1984, Chappell received National Endowment for the Arts Photographer's Fellowships.
