Key Light

The key light is the first and usually most important light that a photographer, cinematographer, lighting cameraman, or other scene composer will use in a lighting setup. The purpose of the key light is to highlight the form and dimension of the subject. The key light is not a rigid requirement; omitting the key light can result in a silhouette effect. Many key lights may be placed in a scene to illuminate a moving subject at opportune moments.

Famous quotes containing the words key and/or light:

    The key to the age may be this, or that, or the other, as the young orators describe; the key to all ages is—Imbecility: imbecility in the vast majority of men, at all times, and even in heroes, in all but certain eminent moments: victims of gravity, customs and fear. This gives force to the strong,—that the multitude have no habit of self-reliance or original action.
    Ralph Waldo Emerson (1803–1882)

    Yes; as the music changes,
    Like a prismatic glass,
    It takes the light and ranges
    Through all the moods that pass;
    Alfred Noyes (1880–1958)
