Class 12 lighting 2

  1. 1. 2Lighting
  2. 2. SOURCE OF LIGHT Natural: – Sunlight – Moonlight – Reflected Daylight Artificial: – Flash – Lamps – Studio Lights – Street Lights
  3. 3. Natural light Natural light comes in a wide range & difference between them can be enormous. The main source of natural light is sun. However it varies in characteristics at different times of the day & weather conditions, turning it into different forms ranging from hard & warm to soft and cool lighting.
  4. 4. Natural light This image probably represents the most straightforward kind of light the sun gives in terms of character.
  5. 5. Natural light Being translucent, clouds also have a major impact on colour & character of sunlight. Light traveling through clouds, is deflected by water particles present in them. This causes rays to bounce around & emerge from it in several directions (diffusion).
  6. 6. Natural light
  7. 7. Midday sunshine
  8. 8. Late afternoon/early evening
  9. 9. Sunset
  10. 10. Dusk
  11. 11. Broken cloud, stormy light, dappled light
  12. 12. Night
  13. 13. Natural vs. Artificial light Natural light is not necessarily outdoor, nor is artificial light exclusively indoor. An indoor scene may rely entirely on filtered window light. Outdoor scenes may rely on artificial lights like lamp post etc.
  14. 14. Artificial & Indoor lighting Light indoors has a different character to that found outside. With human beings in control of light source there is an added twist; that a light is often designed for a specific purpose. e.g. household lights are to give appealing, generally diffused light whereas office lighting is more functional & cost-effective.
  15. 15. Indoor Lights Generally, most artificial light sources are diffused (major exception being spotlights) This is done to soften light & shadows it produce. Even sunlight indoors is diffused as it bounces between walls, floors & ceilings.
  16. 16. Mixed Lighting Its common to see mixture of natural light & artificial light, especially during dawn & dusk leading to an interesting mixtures of colours & intensities (since natural light & tungsten light have complimentary colours in blue & orange).
  17. 17. Firelight and candlelight Light that comes from a flame is even redder than incandescent light from light bulbs & we actually perceive it as orange / red. These light sources are often placed much lower than incandescent lights Often moving as light from fire & candles flickers.
