While practicing as a civil rights lawyer in the American South in the early 70’s, Jacobson became interested in photography, shooting in southern jails and rural areas. After completing a workshop at Apeiron with Charles Harbutt, Jacobson quit his law practice to devote full energies to photography.
In 1976, Jacobson began working in color while photographing the American presidential campaign. It was during this personal project that he began experimenting with strobe and long exposures, a now familiar technique that he pioneered. Later Jacobson left Magnum, along with photographers Charles Harbutt, Mary Ellen Mark, Burk Uzzle and others to found Archive Pictures. During this time, and continuing to the present, Jacobson regularly does assignments for magazines, such as The New York Times Magazine, Fortune, Time, Geo, Stern.
