Lesson 16 : Lighting And Noise

Artificial Lighting

  • This is required because, day light will not be as effective all the time of the day
  • It should be as close to the day light as possible
  • There are 5 systems of artificial lighting
    • Direct: ~100% of light is projected on area of focus
    • Semi-direct: 10-40% light is projected upwards, which reflects from other objects
    • Indirect: ~ 100% light is projected upwards
    • Semi indirect: 60-90% is projected upwards
    • Direct –indirect: light is distributed equally
