• When a sound can replace an image, cut the image or neutralize it. The ear goes more toward the within, the eye toward the outer.
• A sound must never come to the help of a image, nor an image to help the of sound.
• If a sound is the obligatory complement of an image, give preponderance either to the sound or to the image. If equal, they damage or kill each other.
• Image and sound must not support each other, but must work each in turn through a sort of relay.
• The eye solicited alone makes the ear impatient, the ear solicited alone, makes the eye impatient. Use these impatiences. Power of the cinematographer who appeals to the senses in governable way. Against the tactics of speed, of noise, set tactics of slowness, of silence.
