Dean William Semler AM ACS ASC (born 26 May 1943) is an Australian cinematographer and film director.
Semler's vast panoramic shots of the Australian Outback's deserts "...convincingly conveyed a parched, dusty, post-apocalyptic world"[5] and led to international attention for his work.
Semler also acted as cinematographer for the follow-up film to The Road Warrior, Mad Max Beyond Thunderdome (1985).
In 1989, Semler was hired as cinematographer for Kevin Costner's Dances with Wolves (1990), for which he won an Academy Award for Best Cinematography.
In the 2000s, Semler was the cinematographer for a range of movies that included comedies (Nutty Professor II: The Klumps from 2000, and Bruce Almighty from 2003), action films (XXX from 2002 and The Alamo from 2004).
