John Sexton was born in 1953 and is an American fine art photographer who specializes in black and white traditional analog photography. Sexton worked for Ansel Adams from 1979 to 1984 (when Adams died), first as Technical and Photographic Assistant, then as Technical Consultant. Sexton served as Special Projects Consultant to the Ansel Adams Publishing Rights Trust following Adams' death.

Sexton's process consists of large-format 4x5 photography and black and white silver gelatin prints. Like his mentor Ansel Adams, his prints are characterized by great tonal quality resulting from his darkroom virtuosity - Sexton provides abundant technical notes in his books. Most of Sexton's subjects are the natural world, however, unlike Adams, he is more interested in intimate scenes than wide or dramatic vistas, and often photographs them in long exposures made in the "quiet" light of dusk.
