What conditions are required for taking great photos? Aesthetic

sense is important, but you also have to be able to make great

use of the tools in your hand: your camera, and your lens. This is

the reason why it is crucial for you to successfully understand the

functions and operation methods of the camera.

The many buttons and complex menu settings in the digital cam-

era may seem complex but, in fact, most settings are quite simple.

The Samsung smart camera makes it easy even for beginners to

access all the powerful features of the camera due to its easy and

convenient human-centered interface.

Start with automatic

Start o by using SMART AUTO mode, which is fully automatic.

Get used to the functions and names of the camera buttons and

slowly look over the menu until you nd yourself becoming famil-

iar with the camera.

Once you get more familiar with it, you will be able to judge which

functions you need depending on the situation, and the path to-

wards become an intermediate user with adept control over your

camera will be clear. And always remember: digital cameras today

provide outstanding auto recognition functions and exposure pro-

gramming so that even in fully automatic mode, you can always

get excellent results.

Getting to know your camera better willhelp you take excellent photos

Settings and operation methods for shooting 11

Check your basic settings regularly

Before you shoot, there are several things you should regularly

check, like your ISO, white balance, resolution, quality, le format,

exposure compensation, etc. For instance, you may shoot a photo

with high ISO at night and forget to return it to default. The next

day, the high ISO may cause errors while shooting photos during

the day. Or you might change your settings to low resolution at

one point and forget to revert back when you want to shoot some-

thing for printing. Therefore, it is important to be careful.

Try to figure out the names and roles of each button such as the 5-way but-

ton, the jog dial on the top, diverse hot keys and settings for mode dial. Youcan see the menu list of the camera by pressing the MENU button at the

back side of the camera. From the list, it is possible to set the preferred menu

by using the jog dial on the top of the camera or the wheel dial on the back.

Correct resolution setting depends on purpose

If your goal is to upload to your blog or favorite social media, then

low resolution is enough. However, if you want to print a photo lat-

er, then raising the resolution is helpful. If you raise the resolution

to the highest, then it is even possible to print large scale poster-

quality photos. High resolution photos can be used to print large

scale family photos, canvases, wallpapers, etc.

It is good to shoot photos in high resolution as long as the memory

card capacity allows. This is because you can crop and use a part

of the photo depending on how you want to use it. The NX sys-

tem supports high resolutions of up to 2,030 pixels. You can crop

parts of the photo and zoom in on key aspects, while still retaining

the high quality of the image. It is useful to always have an extra

memory card prepared, and it is recommended to move the les

to a computer hard disk after shooting and keep the memory card

empty.

What is resolution?

The resolution settings on a digital camera help decide the size of

the photo. A higher resolution setting creates a larger photo, and a

lower resolution setting makes the photo size smaller. Also, resolu-

tion is in proportion to le size. Hence, the greater the resolution,

the greater the le size.

Setting the resolution correctlydepends on your situation

Resolution settings

The NX system allows you to select a resolution range from the

highest of 20.3 megapixels down to the lowest of 1 megapixel.The NX system also supports resolutions in various ratios includ-

ing 16.9 picture ratio for HD TV output, 1:1 for a square shape and

3:2 for standard photo size. This allows you to select the resolution

that best suits your purpose.

There are two types of le format settings: JPEG and RAW. Both le

formats have advantages and disadvantages and should be used

based on how you intend to use the images you create.

JPEG

JPEG is the most commonly used photo le format. It has the ad-

vantage of being easy to handle due to its outstanding compat-

ibility and small size based on its compression method. Although

it is compressed, there is no big dierence in quality, so it is used

widely for shooting photos.

RAW

RAW is a data type that is literally raw in that it records only data

related to the image formation and does not store other shoot-

ing information. The key advantage of this le format is that you

can edit more freely after the photo is taken, controlling things like

exposure, contrast, white balance, saturation, sharpness and dis-

tortion. However, RAW cannot simply be used as is. After editing,

it must be saved as a JPEG or other similar le format. Also, the le

size is typically quite large and not easy to handle. Therefore, we

recommend that beginners use JPEG.

Choosing the right le format andimage quality setting based on usage purposes


8/32


Image quality settings

For quality settings, you can select between super ne, ne, and

normal. It is optimal to select the best quality, but it is important

to select the setting t for a specic purpose as image quality is

related to size. If your end goal is to upload the image to the web

or a blog, normal quality is preferable, whereas for printing or high

quality purposes, super ne quality would be ideal. As long as the

memory card allows, shooting with super ne quality is recom-

mended. This is because a high quality photo is more advanta-

geous for editing or cropping after shooting.

JPEG + RAW

There is an option to simultaneously save a JPEG and a RAW le

when you shoot. This is a good feature for important photos. You

can have quick access to the JPEG to share immediately, and later

you can use the RAW le to edit. However, it is important to watch

out for increased le size.

The Samsung RAW converter program comes on a CD provided with thecamera. The exposure and white balance settings etc. in RAW files (file exten-

sion: SRW) can be adjusted and calibrated. The files can also be converted

into JPEG or TIFF format

Sensitivity (ISO)

Sensitivity is the degree to which the image sensor reacts when

receiving light. It is measured by ISO (International Organization

for Standardization) standards and referred to as ISO. Higher ISO

sensitivity means that the camera is more sensitive to light. Con-

versely, a lower ISO value denotes lower light sensitivity.

Exposure value and change in qualityISO settings

Selection of higher or lower ISO sensitivity

Consequently, by selecting a higher ISO sensitivity value that can

react suciently to poor lighting conditions, you can take natural

photos in low light or dark places without a ash. You can capture

moments at faster shutter speeds or widen the depth of eld (fo-

cusing range) by closing the aperture.

In other words, there is more shooting freedom with a higher ISO.

However, increasing the sensitivity value causes the overall image

quality to deteriorate. So, for higher quality shots, you should try

to shoot with a low ISO setting. In general, the sensitivity values

between the highest value and the value 2 steps below cover the

range of practical sensitivity values.

shutter speed and low light.

sensitivity with fast shutter speed.

Sensitivity selection tricks

The most common reason why a higher sensitivity setting is need-

ed, despite its low quality attributes, is for situations when camera

blur occurs due to low light and slow shutter speed.

A higher setting is also useful when shooting at night, in low light in-

doors or in museums or concert halls where a ash cannot be used.

Generally, ISO100-200 should be enough in a normal outdoor area

or a bright indoor area and increasing the sensitivity should be un-

necessary if you use a tripod, even when night shooting.

Deciding photo color withWhite Balance

Our eyes adapt easily to light and recognize the color white as

white under any lighting condition. But the color of a photo de-

pends on the light source illuminating the subject. An incandes-

cent lamp actually produces a red light, similar to sunlight at sun-

set. A uorescent lamp produces a blue light similar to the light at

dawn or on a cloudy day. To adjust for this the camera has a whitebalance setting function to suit dierent shooting conditions.

Low color temperature for late afternoon High color temperature for early morning


12/32


Auto White Balance (AWB)

In most circumstances, the auto white balance (AWB) setting pro-

vides satisfactory results. However, you can select a more precise

setting or choose fully manual mode in the white balance menu

if color is leaning too much to one end of the spectrum or your

shooting results are not satisfactory.

White balance manual setting

There is no need to set the white balance precisely if you want to express theatmosphere of the light source when the expression of original color is not

required. Instead, doing the opposite and randomly adjusting the color can

be a fun experience.

Color temperature changedby dierent types of light source

Adjusting color temperature on a digital camera

Unlike lm cameras that used numerous color temperature ad-

justment lters, digital cameras are able to adjust color tempera-

ture by adjusting the white balance function.

The operation method is simple. Enter the white balance set-

tings menu, shoot a photo by lling the entire screen based on an

chromatic color such as white or gray as the standard subject, and

press the settings button. The light source of the subject of inter-

est and the standard subject must be the same, and you must also

be careful not to create shadows.

By adjusting the white balance through achromatic subjects, ex-

pression of original color under the relevant light source is possi-

ble. Conversely, adjusting white balance with blue or yellow paper

creates interesting photos with completely dierent colors.

What is color temperature?

Color temperature refers to the numeric value of color change

when an ideal black body radiates heat. Lord Kelvin discovered it,

which is why the unit K is used. When a virtual black body is radi-

ated in the absolute temperature of -273, from the beginning

until the end of combustion changes color from [dark red][red]

[orange][yellow][white][blue]. Color temperature is the

value expressed through these colors.


14/32


Color temperature of white light as a standard

Generally, the color temperature around noon on a clear day in

sunlight is the same as that of white (colorless) light. The color

temperature at that time of day is 5000K-5500K. The reference

point between higher and lower color temperatures is this color

temperature. That is, a lower color temperature is less than 5000K

and a higher color temperature is over 5500K. Lower color tem-

peratures tend to be closer to red; and higher, closer to blue

White balance settingsfor dierent shooting circumstances

White Balance is compensated by a complementary color to the

ambient lighting. To set the white balance to uorescent, red is

added to oset the blue-green of a uorescent light, while blue is

added to oset the red of an incandescent light. If you understand

this principle, you can use the white balance mode as a color lter.

To introduce a feeling of dawn during the daytime, select Tung-

sten mode to shoot a bluish-toned photo.

Except for screen composition, adjusting the focus is one of the

most important aspects of camera operations. No matter how

beautiful the landscape is, the beauty of a photo is not expressed

well without the right focus. It would not be an overstatement to

say that the start of shooting a photo is adjusting the focus. There

are three modes to adjust the focus, and you must select the ap-

propriate mode based on the subject and situation in order to get

precise focus where you want it.

Starting camera operationsAF mode

If the lens has an AF/MF button, you need to select the correct mode. Set the

button to AF in the case of single AF or continuous AF and to MF in the case of

manual focus. (Single AF and continuous AF can be controlled in the Menu.)


18/32

Single AF mode (single auto focus)

Auto focus mode sets the focus when half-pressing the shutter, so

that the focus becomes xed in that location. If the subject or cam-

era moves, then you can half-press the shutter again to set the focus

again. SAF is appropriate for landscape photos or stationary subjects.

Continuous AF mode (continuous auto focus)

This mode changes the focus based on the movement of the subject

or camera while half-pressing the shutter to set the focus. CAF is ap-

propriate for shooting dynamic subjects such as people and sports.

MF mode (manual focus)

Manual focus mode enables the user to spin the ring to adjust the

focus manually. This mode is relatively less precise than AF mode

because the eect of adjusting the focus must be seen through the

viewnder or display while adjusting the focus. AF mode is useful

for circumstances where focusing on the subject is dicult such as

nights, white walls, and skies.


19/32


AF AREA settings

Select AF: Moves the AF point to the desired area within the screen.

Multi AF: Displays the areas in focus within the screen.

Face Detection AF: Focuses on a person when a person is within

the screen.

Self-Portrait AF: Allows conrmation of whether one's face is within

the screen through a sound eect during self-shots.

AF AREA

The AF (Auto Focus) AREA function can be used to change the po-

sition of the focus area on the screen. When you take a photo of

a subject, the subject might be at the center or at the side of the

scene. Selecting the appropriate AF area allows you to focus andshoot fast.

It is more convenient to move the

AF point via the Select AF to shoot

photos.


20/32


Moving the AF pointer

If you are unable to set the focus because the focus range is cen-

tered, half-press the shutter and press the OK button on the back

to move the focus range to the desired area. Spin the jog dial to

adjust the square that displays the focus range.

You can focus fast if you use the single AF function properly. Skilled

users can focus correctly without moving the AF zone but begin-

ners may need to move the focus zone to get correctly focused.

Changing to SAF AREA

Adjust using the jog dial and wheel key


21/32


AF-LOCK

Fix the focus zone in the center, place the subject in the center

of the screen and then press the shutter button halfway to focus.

Compose the image by moving the camera while continuing to

press and hold the shutter button halfway down to x (lock) the

focus and then press the shutter button all the way down to take

the shot. Once you become accustomed to this process, you can

shoot very fast by locking the focus zone in the center and moving

the focus around the center.

If your camera is not set on a tripod, it is quite a hassle to move

the focus range each time. The AF-LOCK function, together with

half-pressing the shutter, is useful when shooting with your hands.

AF-LOCKSet the focus without changing the AREA

What is half-pressing the shutter?

To half press the shutter press the shutter button down lightly in-

stead of pressing it all the way for shooting. Half pressing changes

the focus mark on the screen to green, adjusts the focus and

displays the shutter speed and the aperture value on the screen

along with the exposure measurement. At this point, keeping

light pressure on the shutter button will maintain the focus as it

is (only for SAF). When actually shooting, it is always best to rst

press the shutter button halfway to check the focused area and

then press the button fully down to take a photo.

Most shoots are possible with AF mode, but it may not function

properly for circumstances such as plain colored walls, skies with-

out clouds, or animals in cages.

For these circumstances, it is useful to transition to MF mode to

set the focus. For more precise focusing, MF Assist is a convenient

function. MF Assist provides a more precise conrmation of the fo-

cus status by expanding the center area of the screen (by up to ve

to eight times) while you spin the focus ring.

Sometimes you need to focus manually.Here's how to use MF mode.


24/32


What is Drive mode?

Drive mode is a function that determines whether to take one pho-

to at a time or consecutive photos. Continuous shooting L mode

takes three photos per second and is recommended for photos of

events or moving portrait photos, and H mode takes eight to nine

photos and is appropriate for situations such as sports matches.

BURST mode takes 30 photos per second and can be used for

reviewing motion, such as doing a meticulous analysis of a golf

swing.

Enter Bracketing Settings in the Menu to

nd three menus (AEB, WBB, and PWB).

In each menu, you can select Exposure

(AEB), Color Temperature (WBB), and Pic-

ture Wizard (PWB). You cannot use AEB

and WBB simultaneously.

AEB (Auto Exposure Bracket) mode

Takes three photos (overexposed, cor-

rectly exposed, and underexposed) and

is useful for photos that are sensitive to

exposure, such as exhibition photos. With

multiple images, it makes sure you alwaysget the right exposure.

PWB (Picture Wizard Bracket) mode

Takes three photos of preset picture wiz-

ard values. The above modes can be set

in Bracket Menu.

Standards for optimum exposure

Then what is the standard for optimum exposure? Optimum expo-

sure is based on neutral gray (a 'gray card') with an average bright-

ness of 18% reectance.

Therefore, when the average reectance of a subject on thescreen exceeds 18%, the camera automatically adjusts the shut-

ter speed to be faster or the aperture value to be smaller in order

to reduce the amount of light. Conversely, when the average re-

ectance is less than 18%, the camera adjusts the shutter speed

to be slower or open the aperture to increase the amount of light.

Optimum exposure

The two key aspects of shooting photos are focus and exposure.

Optimum exposure means receiving the correct amount of light

at an adequate level during shooting. To do this, it is necessary

to adjust the aperture and the shutter speed. A lower exposure

(underexposure) means a darker photo, whereas a higher expo-

sure (overexposure) means a brighter photo due to an excessive

amount of light.

Basics of shooting photosOptimum exposure

Gray card: A neutral grey colored card based

on 18% concentration as a standard for normal

exposure


28/32


The camera's reected exposure meter

The camera measures the amount of light reected o of a sub-

ject rather than measuring the brightness of the light source itself.

Therefore, the camera makes white subjects into gray subjects

because it determines the white to be too bright, and black sub-

jects are turned into gray subjects because black subjects are de-

termined to be too dark. All subjects show an exposure value (EV)

based on 18% concentration as a standard for optimum exposure.

This is the reason manual exposure compensation is at times nec-

essary from the optimum exposure value of the exposure meter.

For bright situations.

(+) EV needed. +1EV

For dark situations.

(-) EV needed. -1EV


29/32


For completely dierent results:Setting the measurement range of exposure

To measure exposure accurately, the appropriate metering mode

must be selected. You can select whether to measure the ex-

posure of the entire screen, measure by increasing emphasis of

the center area of the screen, or measure just a small area of the

screen.

Multi-metering: Measures the average brightness by dividing the

screen. Suitable for subjects with similar brightness within the

screen.

Center-weighted Metering: Measures the center-weighted area of

the screen. Appropriate when the subject and the surroundings

have a slight dierence in brightness.

Spot metering: Measures a portion of the center of the screen

only. Appropriate when the subject and the surroundings have a

slight dierence in brightness.

AE-LOCK

For center-weighted and spot metering, place the main subject at

the center area of the screen and half-press the shutter to meas-

ure. Then while half-pressing the shutter, go back to the previous

screen composition and full-press the shutter to shoot the photo.

You can also set the EV manually before shooting.

Exposure compensation

The camera falsely determines the brightness at times because it measures the over-

all brightness of the screen. For example, when shooting a portrait photo with the sky

as the background, the portrait appears dark because of the surface area that the sky

takes up. Also, there are often times when portrait photos turn out dark during backlit

shots.

On the other hand, sunset photos are shot brighter than what the eye sees and there-

fore reduce the vibe of the atmosphere. The reason for this is due to the lower, dark

area of the screen which makes the camera increase the exposure. The conclusion is

that the exposure measured by the camera cannot be trusted 100%, and based on

the standard of the exposure compensation, the user must determine how to adjust

the EV.

Exposure compensation is not an option but a must

A necessity for good photos is adjusting exposure compensation.

No matter how good the subject and screen composition is, the

brightness and atmosphere must match to provide inspiration. It

is important to check the brightness on the display after shooting

to adjust the EV until reaching the desirable level.

Method of exposure compensation

M mode allows the manual adjust of EV through the aperture and

shutter speed, and the EV function can be used in the P, A, and S

modes. It is designed to adjust 3stops after pressing the exposure

compensation button. Remember to change the EV back to de-

fault after adjusting it during a shot. If you do not turn it back into

default, then future shots will use the latest EV settings and you

may not get the desired photos.
