Types of Light

  • Directional - Precise Beam

– Causes harsh shadows

  • Diffused - General illumination

– omni-directional – no clearly defined shadows – used to illuminate large areas

slide-3
SLIDE 3

Types of Light

  • Directional - precise beam

– Sunlight – Flashlight – car headlights

  • causes harsh shadows
  • aim at specific area w/ o spill into other areas

SLIDE 4

Types of Light

  • Diffused - general illumination

– seems soft and transparent – sunlight on a cloudy day – fluorescent lighting

  • seems to come from all directions
  • covers a large area

SLIDE 5

SHADOWS

  • ATTACHED

– always bound to the illuminated object

  • CAST

– seem independent of the object

COLOR TEMPERATURE

  • The standard by which we measure

reddishness or bluishness of white light

  • measured in Kelvin degrees

(outdoor 5,600k / indoor 3,200k)

– more bluish the higher the color temp – more reddish the lower the color temp

WHITE BALANCE

  • Not all light sources produce the same

whiteness

– candle produces red light – fluorescent light produce blue – flashlight white (unless batteries are low - then red)

  • Proper white balancing is important

LIGHTING INSTRUMENTS

  • SPOTLIGHT (directional)

– defined beam – cause harsh dense shadows

  • FLOODLIGHT (diffused)

– non-directional – transparent shadows (slow falloff)

SPOTLIGTHS

  • Fresnel (fra-’nel)

– most have glass lenses – can be adjusted from spot(or focus) to flood by moving bulb reflector – BARN DOORS – size normally in wattage of quartz-halogen lamp (1K= 1,000 watts)

SPOTLIGHTS

  • ELLIPSOIDAL

– extremely sharp / high intensity beam – rectangular or triangular shape by moveable metal shutters – cookie cutters (gobo)

FLOODLIGHTS

  • No lens
  • Purpose is to create highly diffused / non-

directional light

  • Shadows soft and transparent

LED LIGHTS

  • Litepanels Astra 6x

Safety First

  • be sure power is off
  • Hold-on to ladder rails when climbing
  • always have assistant foot ladder
  • tighten C-Clamp
  • always place safety chain or cable
  • be certain cable is plugged in properly

Techniques

  • Triangle lighting principle

– Key – Fill – Back – background light (optional)
