Light, either natural or artificial, always travels from a source. Light
also travels in a straight line and in all directions. To see that light, it
must travel to our eyes.
Light bounces off opaque objects. Objects of a darker pigmentation
will absorb some of that light. Smooth and shiny objects like mirrors and
spoons will reflect the light so well that you may be able to yourself in
them.
If an object is transparent, light can travel through it but it can also
bend it. This process of refraction can be demonstrated using a pencil
placed in a clear glass of water. The pencil looks as if it was chopped in
half!
Today, we rely mostly on artificial light to help us in many activities
such as seeing, driving, reading… Power stations provide electricity to
cities while pylons and cables are used to carry electricity from house to
house.
Artificial light is something we take for granted. However, 100 years
ago people had to rely on oil, gas and fire to light their houses. Edison’s
light bulb was invented in 1880 but could only stay alight for a few
minutes. Things have evolved and you can now buy energy saving bulbs
lasting up to two years.
On the other hand, it is nowadays very difficult to experience total
darkness as the moon, street lights or a simple light on a digital clock
might interfere. When it’s dark, other senses can be used to find or
identify objects.
Contrary to what many think, the Moon is not itself a source of light.
Light is actually reflected onto the Moon from the Sun and then bounced
back to Earth.
Light travels in a straight line. That is why you can see an identical
image of yourself when you are looking in a flat mirror. In fact, what you
are seeing is a reflection of yourself.
A reflection occurs when light rays bounce off objects and into our
eyes.
For a reflection to occur, you need a light source such as the Sun or a
light bulb. You also need a reflective surface such as a mirror or glass.
Sometimes, light reflected from certain objects can have interesting
results. Bendy mirrors are a classic example of how images can be
distorted.
Convex mirrors bend out and will stretch you and make you appear
taller.
Concave mirrors bend in and will squish you and make you appear
shorter.

ASSIGNMENT ONE
For shadows to come alive, three variables are needed: a light
source, an object to block that light and a surface onto which shadows
can form.
All objects create shadows, whether they are opaque, translucent or
transparent.
Shadows vary in size and may look like the objects that make them.
However, depending on the position of the light source and the distance
between that light, the object and the surface, they can look bigger or
smaller.
Shadows are shorter before mid-day, then longer until they
disappear as the Sun sets. The Sun doesn’t cast a shadow when positioned
directly above objects. That is why there are no shadows at mid-day,
when the Sun is at its highest. 51
Light needs to shine behind you for your shadow to appear in front
of you. Likewise, if the source of light is to your left, your shadow will
appear on your right.
Take photos of the same subject in six to eight different lighting situations. Use an inanimate object that can be easily moved around. For best results, make it an object you like and are interested in
photographing.
a. Use the same location but different times of day for three images using a natural light source.
b. Use different types of light for the remaining images – direct, indirect (multiple sources),
indoors, out of doors, artificial, flash.
c. Make note of the time of day and location for each set of photos.
d. Note: This exercise doesn’t have to take all day. Spend five minutes with each location/light
source and take a few photos with different points of view relative to the light source (shadow
vs. illuminated side, etc.), then move on.

Assignment 2
LIGHT AND SHADOWS
ASSIGNMENT SHEET
Clive Brunskill
What are we doing?
- Learning to look at light and shadow in a new way
- Shooting digital photos to explore the ways in which light & shadow are important elements
- Demonstrating that you can make a turn a color image into a black&white image in Photoshop.
- Adjusting the LEVELS and CURVES of our images in Photoshop.
What do we have to turn in?
2 black & white digital images that show:
- 1 photo that shows shadows as objects
- 1 photo that shows an aspect of light
What should I make sure to do?
- Make sure to meter every photograph properly for the correct exposure. Use a gray card or object if you need to. If the subject has really bright areas and really dark areas, then meter both and pick an exposure in between.
- Make choices to create visually strong compositions with camera angles, orientation, distance, fore/mid/background
- Make sure to use WHITE BALANCE and EXPOSURE COMPENSATION if needed. Also make sure that photo is in focus
What should I think about?
- Think about every single object you are including in the frame. Are you sure you want it to be there? Pay attention to things in the background.
- Is there clutter in your photograph? Think about the "10 Commandments"
- Think about what you are trying to say with the photograph. Is it just "pretty", or are you trying to tell the viewer something about yourself or the world?
- Think about the camera angle.is it boring? Does it help to say something about the subject? Look HERE for more ideas about angles and zoom
- Think about where you point you camera to meter a scene. Is it a really dark place or a really light place? Try to meter in a neutral place, not too light or too dark.
