LIGHTING

LIGHTING
2

• Without light it is virtually impossible to make
  television images.
• Lighting has both a technical and aesthetic
  function
• The right light will create excellent pictures

3
Amount of light

• The amount of lighting a shot will determine how
  clearly we see the images
• The type of light affects the color

4
MOOD

• Lighting affects moodtwo messages can be
  conveyed in the same room with different
  lighting.

5
Video Cameras

• Video cameras require more light than other
  cameras.
• There must be enough light reflected off a scene
  to produce an image.

6
BRIGHTNESS

• The intensity or brightness of the light on a
  subject affects how well a camera can see it
• Too little too dark and underexposed
• The image will be soft and underexposed
• Will create a grainy look (this is called picture
  noise)
• Bright light creates sharp and clear images

7
BASE LIGHT

• The light that already exists in an environment
  is its base light.
• If you turn the lights off in a room you lower
  the base light
• If you turn more light on then you raise the base
  light
• Base light is often all you will have to work
  with but that doesnt mean you cant think about
  lighting

8
DIRECTION

• The direction of a light source affects the way
  light and shadow fall on a subject.
• Direction is determines by how you position both
  the subject and the lighting fixture.
• Light from the side produces dimension and
  texture where as light coming directly in front
  (from the angle of the camera) will reduce
  texture and shape.

9
QUALITY

• The quality of light refers to whether it is hard
  or soft .
• Hard light creates sharp and well defined dark
  shadows.
• It brings out the shapes and textures of the
  subject
• Hard light is created by sunlight and directional
  focused lighting fixtures

10
SOFT LIGHT

• Soft light is diffused and creates very few or no
  shadows (like a cloudy day)

11
COLOR

• Light also determines the color an object will be
• White light is an equal mixture of colors across
  the full spectrum of red, orange, yellow, green,
  blue, indigo and violet
• Our eyes compensate for these differences in
  color temperature
• Cameras dont
• The type of light affects the color of the object

12
COLOR TEMPERATURE

• The exact color and tone of light is called color
  temperature
• Color characteristics are classified on a KELVIN
  (K) color temperature scale.
• This scale measures the degree of red or blue in
  the light (not the heat or brightness)
• The higher the color temperature the more
  prominent the blue tones

13
COLOR TEMP.

• As the light gets brighter or as the light source
  changes the color temperature changes
• Daylight has more blue tones
• Video lights usually have red tones
• Lights in homes are even redder
• Fluorescent lights are green

14
Example of Color Temperature

Warm(2000-3000K Mid-range(3000-4000K) Cool(4000K )
15
WHITE BALANCE

• Most cameras will white balance automatically
  but some will have the option to do this manually
• To do so you would select the color temperature
  for the dominant light source, place a white
  object or card in that areas point the camera at
  the white object completely filling the screen
  and perform the white balance function

16
POSITION OF LIGHTS

• Read the hand outs and answer the questions then
  you may work on your brochure (which you should
  do very well on) or your critique, or your
  commercial.
