Concepts in Photography
Standing photography
Compose your shot; stand up straight with your feet shoulder-length
apart, and keep your elbows pointed down.
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 slow shutter speed,
hold your breath to minimize body movement.
Holding the camera
Hold the camera with your right hand and place your right index nger on
the shutter button. Place your left hand under the lens for support.

14
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 ( ). You can rotate the display a
maximum of 90° downward or 180° upward ( ). You can also rotate the
display 180° upward and fold it ( ).
• Keep the display closed when the camera is not in use.
• Tilt the display only within the angle allowed. Failing to do so may damage
your camera.
• Use the Wi-Fi functions when the display is set as shown in illustrations
and .

15
Concepts in Photography
Low-angle shot
A low-angle shot is a shot from a camera positioned below your eyeline,
looking up the subject.
High-angle shot
A high-angle shot is a shot from a camera positioned above your eyeline,
looking down on the subject.

16
Concepts in Photography
Aperture
The aperture 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 related to the amount of light: a larger aperture allows more light and a
smaller aperture allows less light.
Aperture sizes
Minimum aperture Medium aperture Maximum aperture
Aperture opened slightly Aperture opened wide
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 ne-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 eld
You can blur or sharpen the background of a photo by controlling the
aperture. It is closely related to the depth of eld (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 aects 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

18
Concepts in Photography
Shutter speed
Shutter speed refers to the amount of time it takes to open and close the
shutter. 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, 1/1,000 s, 1/2,000 s, and so on.
Exposure
+1 EV
-1 EV
1 s 1/2 s 1/4 s 1/8 s 1/15 s 1/30 s
Shutter Speed
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.
The photos below illustrate that a slow shutter speed allows more time
for light to enter the camera. This adds a motion blurring eect to moving
objects. On the other hand, a fast shutter speed allows less time to let light
in and the photo 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 lm 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.
Changes in the quality and brightness according to ISO sensitivity
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 slow shutter
speed. However, in a dark place or at night, a low ISO sensitivity will
result in a blurry photo. Therefore, it is recommended to increase the ISO
sensitivity by a moderate amount.
