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.
