Inner Orientation

• Lighting to establish mood and communicate
  emotion
• Three functions
• Establishing mood atmosphere
• Predictive lighting
• Lighting as dramatic instrument

2
Establish Mood

• High-Key Lighting
• Abundance of light
• Slow falloff
• Light background
• Examples
• news rooms

• Upbeat

3
Establish Mood

• Low-Key Lighting
• Less light
• Fast falloff, highly selective
• Background predominantly dark.
• downbeat

4
Above Below Eye Level

• Based on location of key light.
• Used to key light being above us
• Eye-level is the eyes of the subject or middle
  portion of object
• Above-eye-level normal
• Below-eye-level disorienting

5
Predictive Lighting

• Portend upcoming event
• Change in normalcy
• Drastic change
• From high-key to low-key
• From above-eye-level to below-eye-level

Application of Lighting
7
Use of Lighting Instruments

• Lamps are called Quartz lamps
• tungsten-halogen lamps
• 500 200 watts
• Get very hot
• Rather expensive (15 per bulb)

8
Attachments to Lighting Instruments

• Barn Doors
• Adjustable metal flaps
• Mask unwanted light
• Cut down on spill
• Soft cut off/edge
• Filter Frames
• Slide over light
• Can hold
• Scrim
• Diffuser
• Gel

Three Point Lighting

• In typical lighting setups, lighting instruments
  have four functions
• KEY LIGHT
• FILL LIGHT
• BACK LIGHT
• BACKGROUND LIGHT

10
Three-Point Light

• Used to get positive results
• Used in many situations
• To picture at right, 4 light sources
• Key, to left
• Dim fill, to right
• Back light, on hair
• Background light

11
Key Light

• Main light
• Most defines appearance
• Often in middle of hard-soft continuum
• Placed at a 30? to 45 ? to left or right side of
  the camera.
• 45? is preferable because brings out texture and
  form.

12
The Key Light
13
Does it matter what side the key light is on?

• Sometimes.
• Put the light on the subjects best side.
• Follow source. Is there a set feature or a story
  element that is producing the light?
• Consistency within the scene.
• Light for practicality (walls, obstructions, etc.)

14
The Fill Light

• The key light will produce shadows.
• One purpose of the fill light is to fill in
  shadows.
• Placement of fill light
• Fill light is placed 90? from the key light
• If you were to draw a line from key to subject to
  fill, you would get a right angle.
• This wide sweep can give coverage if the subject
  moves.

15
The Fill Light
16
Fill Light

• Should be softer than key light
• Avoid a second set of shadows
• Good choices
• Use a diffuser
• Use indirect light
• Using the sun
• Can use the sun as a key light
• Use a reflector (or a large white poster board)
  to bounce light as a fill.

17
The Back Light

• Function of the backlight is to separate the
  subject from his/her background.
• Creates a rim of light around the subject.
• Sometimes called a hair light
• If viewed from above, you should be able to draw
  a straight line from the backlight to the camera.

Back Light

Vertical Placement of Lights
20
Background Lights

• Used to illuminate the background area.
• Add depth between scene elements.
• Can use any type of light
• Should be fairly even illumination.
• Often placed on same side as the key light.
