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

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).

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. 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.

17. 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.

20. 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).

23. 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.
