This documentary explores the life of Jack Cardiff, a former child actor who went on to achieve great things in film. But Cardiff didn't excel in front of the camera; he mastered the camera itself, using his painting background to perfect the art of lighting in cinema. Cardiff's talent as a cinematographer is seen in clips from some of his most acclaimed works, like ''Black Narcissus'' and ''The Red Shoes,'' while the praise of luminaries like Martin Scorsese cements his legend.
