P.H. Emerson (1856-1936) believed that "nothing in nature has a hard outline" and attempted to emulate natural eyesight by employing differential focus, wherein the subject of the photograph is rendered with clarity and everything else gradually falls out of focus. Emerson's great-grandson, photographer Stephen Hyde narrates these videos on the artist's life and approach to photography.
