Concepts in Photography
Shooting postures
A correct posture for stabilizing the camera is necessary for taking a
good photo. Even if you hold a camera correctly, the wrong posture
can cause the camera to shake. Stand up straight and remain still to
maintain a steady base for your camera. When shooting with a low
shutter speed, hold your breath to minimize body movement.
Holding the camera
Hold the camera with your right hand and place you right index finger
on the shutter button. Place your left hand under the lens for support.
Standing photography
Compose your shot; stand up straight with your feet shoulder-length
apart, and keep your elbows pointed down.
13
Concepts in Photography
Crouching photography
Compose your shot, crouch with one knee touching the ground, and
keep a straight posture.
Using the display
Swing the display outwards 180° and rotate it up or down for
high- and low-angle photos or self portraits (
display a maximum of 90° downward or 180° upward (
also rotate the display 180° upward and fold it (
). You can rotate the

Concepts in Photography
Low-angle shot
A low-angle shot is a shot from a camera positioned below the eyeline,
looking up the subject.
High-angle shot
A high-angle shot is a shot from a camera positioned above the eyeline,
looking down on the subject.
15
Concepts in Photography
Aperture
The aperture, a hole that controls the amount of light that enters the
camera, is one of the three factors that determine the exposure. The
aperture housing contains thin, metal plates that open and close to let
light through the aperture and into the camera. The size of the aperture
is closely related to the brightness of a photo: the larger the aperture,
the brighter the photo; the smaller the aperture, the darker the photo.
Aperture sizes
Minimum aperture Medium aperture Maximum aperture
The size of the aperture is represented by a value known as an
“F-number.” The f-number represents the focal length divided by the
diameter of the lens. For example, if a lens with a 50 mm focal length
has an f-number of F2, the diameter of the aperture is 25 mm.
(50 mm/25 mm=F2) The smaller the f-number, the greater the size of
the aperture.
The opening in the aperture is described as the Exposure Value (EV).
Increasing the Exposure Value (+1 EV) means the amount of light
doubles. Decreasing the Exposure Value (-1 EV) means the amount of
light halves. You can also use the exposure compensation feature to
fine-tune the amount of light by subdividing exposure values into 1/2,
1/3 EV, and so on.

Concepts in Photography
Aperture value and the depth of field
You can blur or sharpen the background of a photo by controlling the
aperture. It is closely related to the depth of field (DOF), which can be
expressed as small or large.
A photo with a large DOF A photo with a small DOF
The aperture housing contains several blades. These blades move together
and control the amount of light passing through the center of the aperture.
The number of blades also affects the shape of light when shooting night
scenes. If an aperture has an even number of blades, light divides into an
equal number of sections. If the number of blades is odd, the number of
sections is double the number of blades.
For example, an aperture with 8 blades divides light into 8 sections and an
aperture with 7 blades into 14 sections.
7 blades 8 blades
17
Concepts in Photography
Shutter speed
Shutter speed refers to the amount of time it takes to open and close
the shutter, and it is an important factor in the brightness of a photo, as
it controls the amount of light which passes through the aperture before
it reaches the image sensor.
Usually, the shutter speed is manually adjustable. The measurement
of the shutter speed is known as the “Exposure Value” (EV), which is
marked in intervals of 1 s, 1/2 s, 1/4 s, 1/8 s, 1/15 s, 1/1000 s,
1/2000 s, and so on.
+1 EV
Exposure
-1 EV
Therefore, the faster the shutter speed, the less light will be let in.
Likewise, the slower the shutter speed, the more light will be let in.
As the photos below illustrate, a slow shutter speed allows more time
to let light in, so the photo becomes brighter. On the other hand, a fast
shutter speed allows less time to let light in and the photo becomes
darker and more easily freezes subjects in motion.

Concepts in Photography
ISO sensitivity
The exposure of an image is determined by the sensitivity of the
camera. This sensitivity is based on international film standards, known
as ISO standards. On digital cameras, this sensitivity rating is used
to represent the sensitivity of the digital mechanism that captures the
image.
ISO sensitivity doubles as the number doubles. For example, an
ISO 200 setting is capable of capturing images at twice the speed of an
ISO 100 setting. However, higher ISO settings can result in “noise”—
small specks, spots, and other phenomena in a photo that give the shot
a noisy or dirty appearance. As a general rule, it is best to use a low
ISO setting to prevent noise in your photos, unless you are shooting in
darkened environments or at night.
Because a low ISO sensitivity means the camera will be less sensitive
to light, you need more light to have an optimal exposure. When using
a low ISO sensitivity, open the aperture more or reduce the shutter
speed to allow more light to enter the camera. For example, on a sunny
day when light is abundant, a low ISO sensitivity does not require a low
shutter speed. However, in a dark place or at night, a low ISO sensitivity
and a fast shutter speed will result in a blurry photo.

Concepts in Photography
How the aperture setting, shutter speed, and ISO sensitivity control exposure
The aperture setting, shutter speed, and ISO sensitivity are closely
interconnected in photography. The aperture setting controls the
opening that regulates the light that enters the camera, while the shutter
speed determines the length of time that light is allowed to enter.
ISO sensitivity determines the speed at which the film reacts to light.
Together, these three aspects are described as the triangle of exposure.
A change in shutter speed, aperture value, or ISO sensitivity can be
offset by adjustments to the others to maintain the amount of light.
The results, however, change according to the settings. For example,
shutter speed is useful in expressing movement, aperture can control
the depth of field, and ISO sensitivity can control the graininess of a
photo.

Concepts in Photography
Correlation between focal length, angle, and perspective
Focal length, which is measured in millimeters, is the distance between
the middle of the lens to its focal point. It affects the angle and
perspective of captured images. A short focal length translates into a
wide angle, which allows you to capture a wide shot. A long focal length
translates into a narrow angle, which allows you to capture telephoto
shots.

Normally, a lens with a wide angle is suitable for shooting landscapes and
a lens with a narrow angle is recommended for shooting sports events or
portraits.
21
Concepts in Photography
Depth of field
Portraits or still-life photos mostly acclaimed by people are the ones on
which the background is out of focus so the subject looks pronounced.
Depending on the focused areas, a photo can be blurred or sharpened.
This is called ‘a low DOF’ or ‘a high DOF’.
The depth of field is the focused area around the subject. Therefore,
a small DOF signifies that the focused area is narrow and a large DOF
means the focused area is wide.
A photo with a small DOF, which stresses the subject and makes the
rest of it blurred, can be obtained by using a telescope lens or selecting
a low aperture value. Conversely, a photo with a large DOF which
shows all the elements on the photo sharply focused can be achieved
by using a wide angle lens or selecting a high aperture value.
What controls out-of-focus effects?
DOF depends on aperture value
The wider the aperture is (namely the lower the aperture value), the
lower the DOF becomes. Under the condition where the other values
including shutter speed and ISO sensitivity are equal, a low aperture
value leads to a photo with a low DOF.

with a longer focal length than a telescope lens with a short focal length
is better to capture a photo of a low DOF.

DOF depends on the distance between the subject and
the camera
The shorter the distance between the subject and the camera is, the
lower the DOF gets. Therefore, taking a photo close to a subject can
result in a photo of low DOF.

DOF preview
You can use the Depth preview button to get an idea of what your shot
will look like before shooting. When you press the button, the camera
adjusts the aperture to the predefined settings and shows the results on
the screen. (p. 129)
Composition
It is fun to capture a photo of the beauty of world with a camera. No
matter how the world is beautiful, however, a poor composition cannot
capture the beauty of it.
When it comes to composition, it is very important to prioritize subjects.
Composition in photography means arranging objects in a photo.
Usually, abiding by the rule of thirds leads to a good composition.
Rule of Thirds
To use the rule of thirds, divide the image into a 3x3 pattern of equal
rectangles.
To compose photos that best emphasize the subject, make sure the
subject is located at one of the corners of the center rectangle.

Concepts in Photography
Using the rule of thirds will create photos with stable and compelling
compositions. Below are a few examples.
Photos with two subjects
If your subject is in one corner of the photo, it creates an unbalanced
composition. You can stabilize the photo by capturing a second subject
in the opposite corner to balance the weight of the photo.
Subject 2
Subject 1
Unstable Stable
Subject 1
When taking landscape photos, centering the horizon will create an
unbalanced effect. Give more weight to the photo by moving the
horizon up or down.

Flash
Light is one of the most important components in photography. It’s
not easy, however, to have an enough amount of light anytime and
anywhere. Making use of a flash allows you to optimize light settings
and create a variety of effects.
Flash, also known as strobe or speed light, helps to create adequate
exposure in low-light conditions. It is also useful in light-abundant
situations. For example, flash can be used in compensating the
exposure of a subject’s shadow or capturing clearly both the subject
and the background in backlit conditions.

Flash guide number
The model number of a flash refers to the flash’s power, and the
maximum amount of light created is represented by a value known
as a “guide number.” The bigger the guide number, the more light is
emitted from the flash. The guide number is achieved by multiplying the
distance from the flash to the subject and the aperture value when the
ISO sensitivity is set to 100.
Guide number = Flash to Subject Distance X Aperture value
Aperture value = Guide number / Flash to Subject Distance
Flash to Subject Distance = Guide number / Aperture value
Therefore, if you know the guide number of a flash, you can estimate an
optimum flash to subject distance when setting the flash manually. For
example, if a flash has a guide number of GN 20 and is 4 meters away
from the subject, the optimal aperture value is F5.0.

Bounce Photography
Bounce photography refers to the method of bouncing light off of
the ceiling or walls so that the light spreads evenly over the subject.
Normally, photos captured with flash may appear unnatural and cast
shadows. Subjects in photos captured with bounce photography cast
no shadows and look smooth due to evenly spread light.
