Photographs
People take photographs to remember places they have visited, people
whom they have met and events that have taken place, What are other
reasons why people take photographs? It has been said that a picture is
worth a thousand words. In what way is this true?
For geographers, a photograph is a visual record of information about
aplace or an area at a particular time. Photographs are useful in helping
us to understand the physical and human features of a place. They help
us form.an accurate image of the world and give a Sense of reali

oo 5Photographs as sources of information
Like maps, photographs provide information about a place. However,
while maps use symbols to represent features, photographs show
the actual features. For example, a map may represent rice
farming on slopes by means of symbols and contours. On
the other hand, a photograph of the same area shows
the rice farms as they are in real life, For example,
it shows how the slopes have been cut into terraces.
Hence, photographs are useful for studying features and
processes that may not be drawn or shown on maps.
Photographs are also useful if we have never seen the
place atures in the area before. Because the world is,
so big, itis impossible for us to visit every place for ourselves
in our lifetime! Hence, photographs allow us to see and study

Ifyou compare a photograph of yourself as a toddler and a photograph

the years, comparing old and new photographs of an area allows us (0

activities. For instance, the photographs below show Jurong Industrial

development of the Jurong area and the changes that have taken place
over time.

Photographs as a tool to study the environment
Photographs are used as tools to study features and oceurrences on the
Earth, Forinstance, photographs help us to study the extent of forest fires
and their impact on the environment. By observing our environment, we
will be more aware of how our actions affect the Earth. We will also be
more careful not to cause further damage to our environment.

‘There are three main types of photographs: landscape photographs,
acrial photographs and satellite images. Each type of photograph
presents different information about a place or feature, and is used
for different purposes.
Landscape photographs
Landscape photographs are photographs taken at the
ground level. A landscape photograph shows a big picture
of an area, as if we are standing in front of it. It shows the
main physical or human feature, and other less important
details around it, We use this type of photograph when
studying a feature in detail,
Aerial photographs

Some aerial photographs show a vertical view of a place from the
top. Such photographs are taken by a camera which points straight
down on the Barth’s surface
These photographs are useful for studying the layout ofa settlement,
They are often used by town planners or geographers who are
interested to see how a city develops.
Satellite images
With advanced technology, satellite images of the Earth’s surface can
be taken by instruments on board a satellite in space. A satellite is an ia Tixtiedtulalos al

How Do We Read and Interpret
Photographs?
We learnt that photographs are useful in helping us to
understand physical and human environments, In order to
Ashe red wert as much information as possible from a photograph,
in Sumava on 19 June 204, They we need to interpret it in a systematic way. Follow these steps below,
msec to read and interpret photographs.
Step 1: Divide the photograph into three sections
In order to refer to the different parts of a photograph easily, we can

human features
Identify the main feature in the photograph and state the section where
the feature is located. If the photograph shows a main feature, we can
describe it straight away. If the photograph shows an area of land, we
1 identify the features in the area.
Physical features
Physical features include rivers, plants, mountains and
plains. We also describe how the land looks like. Is the
land steeply sloping or gently sloping? For example,
the background of Fig 6.12, we see that there are
mountains with steep slopes.
Human features

How does the environment affect people? How have people changed
the environment?
‘As seen in Fig 6.12, the environment affects where people choose
to stay. People have built their homes at the foot of the mountai
where the land is flat, At the same time, the people have changed
their environment by building houses and roads on the land

Seeing the World Through Photographs
Different types of photographs provide different information about
the physical and human environments, They also show us what human
activities are carried out in an area, We are thus able to interpret
the interrelationship between people and the environment from the ave
photographs. What are the steps to
reading and interpreting
photographs?

Skills.
Photographs are an important tool ‘or understanding physical and human
environments. When interpreting a shotograph, itis important to examine
the photograph closely and look at every big and small feature shown.
Although the more important features usually take up a large section in
@ photograph, details that are less obvious may also provide important
information about the environment.
Let us now try out the steps to interpret photographs!
1. Finda photograph that shows an interrelationship between people and
the environment. You can download the photograph from the Internet,
make a photocopy from a book, or cut it out from the newspapers
2. Use the three steps that you have learnt on interpreting photographs
(pages 68 and 69), and write down four to six sentences to describe
what you see.
Describe the interrelationship between people and the environment.
Exchange your photograph witha classmate, and interpret each other's
photograph.
5. Compare your interpretations of the two photographs with your
classmate’s. What have you leaint from your classmate's interpretation
of the photographs?
