John Alton

The Hungarian-born John Alton, who emigrated to the USA in 1919, shot his first films in Argentina in the 1930s and began his prolific Hollywood career with "The Courageous Dr. Christian" (1940), directed by Bernard Vorhaus. He demonstrated a masterful command of chiaroscuro, the representation of light and shade without regard to color, with his work for Anthony Mann, notably "T-Men" (1947) and "Border Incident" (1949). Alton became known as a master of film noir, as well for his visual puns, usually involving shadows.
