I try to show their way of life." and that "I feel an affinity for people who haven't had the best breaks in society. What I want to do more than anything is acknowledge their existence". Mark was well known for establishing strong relationships with her subjects. For Ward 81 (1979), she lived for six weeks with the patients in the women’s security ward of Oregon State Hospital, and for Falkland Road (1981), she spent three months befriending the prostitutes who worked on a single long street in Bombay. Her project "Streets of the Lost" with writer Cheryl McCall, for Life, produced her book Streetwise (1988) and was developed into the documentary film Streetwise, directed by her husband Martin Bell and with a soundtrack by Tom Waits. Mark was also a unit photographer on movie sets, shooting production stills of more than 100 movies, including Arthur Penn's Alice's Restaurant (1969), Mike Nichols' Catch-22 (1970) and Carnal Knowledge (1971), Francis Ford Coppola's Apocalypse Now (1979), and Baz Luhrmann's Australia (2008).

She published 18 books of photographs and contributed to publications that include Life, Rolling Stone, The New Yorker, New York Times, and Vanity Fair;.
