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.

Natural light

• This image probably represents the most
  straightforward kind of light the sun gives in
  terms of character.

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).

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
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.

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.
