Health and safety information
Prevent damage to subjects’ eyesight.
Do not use the ash in close proximity (closer than 1 m/3 ft) to people or
animals. If you use the ash too close to your subject’s eyes, this can cause
temporary or permanent eyesight damage.
Keep your camera away from small children and pets.
Keep your camera and all accessories out of the reach of small children
and animals. Small parts may cause choking or serious injury if swallowed.

The ash is very hot when red and may burn your skin.
When you use the AC charger, turn o the camera before you
disconnect the power to the AC charger.
Failing to do so may result in re or electric shock.
Disconnect the charger from the wall socket when not in use.
Failing to do so may result in re or electric shock.
Do not use a damaged power supply cord, plug, or loose outlet
when you charge batteries.
This may cause a re or electric shock.
Do not allow the AC charger to come in contact with the +/-
terminals on the battery.
This may cause a re or electric shock.
Do not drop or subject the camera to strong impacts.
Doing so may damage the screen or external or internal components.
Exercise caution when you connect cables and install batteries
and memory cards.
If you force the connectors, improperly connect cables, or improperly
install batteries and memory cards, you can damage ports, connectors,
and accessories.
Keep cards with magnetic strips away from the camera case.
Information stored on the card may be damaged or erased.
Never use a damaged battery or memory card.
This may result in electric shock or camera malfunction or cause a re.
Do not place the camera in or near magnetic elds.
Doing so may cause the camera to malfunction.
Do not use the camera if the screen is damaged.
If the glass or acrylic parts are broken, visit a Samsung service center to

cool down.
• Prolonged usage of the camera may overheat the battery and raise
the internal temperature of the camera. If the camera stops operating,
remove the battery and allow it to cool down.
• High internal temperatures may result in noise in your photos. This is
normal and does not aect your camera’s overall performance.
Avoid interference with other electronic devices.
Your camera emits radio frequency (RF) signals that may interfere
with unshielded or improperly shielded electronic equipment, such as
pacemakers, hearing aids, medical devices, and other electronic devices in
homes or vehicles. Consult the manufacturers of your electronic devices
to solve any interference problems you experience. To prevent unwanted
interference, use only Samsung-approved devices or accessories.
Use your camera in the normal position.
Avoid contact with your camera’s internal antenna.

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.

15
Concepts in Photography
Crouching photography
Compose your shot, crouch with one knee touching the ground, and keep
a straight posture.
Using the display
To take photos at high or low angles, tilt the display up or down. You can
tilt the display up to 90° upwards ( ) or 45° downwards ( ).
• 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.

16
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.

17
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 size of the aperture opening is dened 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 changing the size
of the aperture. A large aperture gives your photos a shallow depth of
eld (DOF). Objects immediately in front of or behind your subject will
be blurred, while the subject will be in focus. A small aperture gives your
photos a deep depth of eld. Objects far in front or far behind your subject
and your subject will be in focus.

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.

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.
Shutter speeds are measured in seconds and parts of a second. On
many cameras, the shutter speeds are approximately halved with each
succeeding setting - 1 s, 1/2 s, 1/4 s, 1/8 s, 1/15 s, etc. Like successive
aperture settings, each successive shutter speed setting lets in about half
the amount of light. Consequently, each successive shutter speed setting
equals an EV (Exposure Value) change of about 1 EV.

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.
A slow shutter speed allows more light into the camera to make photos
brighter. However, because the shutter is open longer, moving subjects
appear blurred. A fast shutter speed allows less light in to make photos
darker. However, because the shutter is open for a shorter time, moving
subjects look sharper and more focused.
