lighting Lighting is the direct manipulation of light and shadows for a specific communication purpose. – Zettle Suggested reading Sight, Sound and Motion, chapter 2
lighting You clarify and intensify an event through light (as you do through composition, editing, sequencing, sound….).
light and shadow • Lighting is about controlling shadows not illuminating an object.

Lighting: outer orientation • Shape • Texture • Position • Time of year • Time of day
Attached SHADOWS “Attached shadows on faces create a dramatic composition in John Huston’s Asphalt Jungle”
Cast shadows Last Year at Marienbad
Controlling Falloff -- manipulation of fill light • directional beam sharp fall off • floodlights produce slow fall off • slowing fall off - attached shadow area somewhat transparent and reducing contrast between light & dark • through amount of fill light or w/ reflectors • foggy day / no harsh shadows • not illuminated side that tells us about lighting but the shadows
Stand lighting set-up Three point lighting Triangular arrangement of lights Key is main source of light and reveals shape of object. Placed above and in front of head Fill light is placed on opposite side of camera as key and fills in the shadows Back light shines on back of head to increase separation from

Lighting approaches There are two main categories for lighting: • high key lighting • low key lighting
High key / flat lighting Key and fill lights are almost equal Very little contrast between lightest and darkest areas of set Almost no shadows – used for musicals, comedies and game shows
Low key Key strong, very little fill light Strong contrast between lightest and darkest areas of set Creates strong shadows – suspense genres like film noir
Chiaroscuro Organic – scene looks realisticDirectional – leads eye to part of the frame Spatial – to define spaceand balance composition Thematic – supportstheme or story Emotional – establish or emphasize a mood
Chiaroscuro Lighting Fast fall-off (hard light) with light/dark contrast Articulates space, intensify three dimensions Expressive quality – light comes from within scene Supper at Emmaus (Caravaggio)
Rembrandt Lighting Selectivity and fast fall-off Only some areas are lit whileothers are unlit or under-litThe fall-off is fast but there is enough light to make attachedshadows transparent Background is dark but has enough illumination to set offoutline of central figure
Cameo lighting Illuminates subject only Usually key and back lights illuminate subjectsNo fill light is used Subjects stand out againstdarker background
Flat lighting Diffuse light Light seems to come from all directions Opposite of chiaroscuroVery slow falloff and transparent attached and cast shadows High key, implies high energy, efficiency, mechanization, depersonalization
Other considerations • Diffuse / soft • hard • Side • Back
Silhouette Lighting Both chiaroscuro and flat Chiaroscuro because of lightand dark contrast Flat because it emphasizescontour rather than volume ortexture Opposite of cameo as it lightsbackground and not figure
Direction of Light: Emphases Shape, Outline Flattens The Image Sculpts Volume
Clicker question: best description of lighting High key light Low key light Prescriptive Chiaroscuro Flat
