LG G4 Camera

User Guide

It is true that many believe that you can't beat the quality of

a professional camera no matter how good the quality of photo being

taken by a smartphone is. I was one of those who had doubts about a

smartphone camera's performance. However, while on this project, I had

to reverse my stereotype after experiencing the amazing functions of the

G4 camera. The G4 camera guideline was written in simple terms for new

users. Our goal was to show that our normal, everyday life is the best

material for works of art through our daily surroundings and landscapes.

I hope that the joy and warmth I felt when taking pictures can be

transferred to the readers of this guideline and I wish for you to discover

your potential as a photographer.

★Exposure adjustment :The camera by default represents white to gray, and black to less black.

Because the actual color can be represented differently you can take photographs that are similar to

what we see in real life by correcting the exposure to either darker (-) or brighter (+).

★Histogram :A type of a graph indicating the picture brightness. The shape of the graph will tilt to

the right if excessive light enters the sensor causing pictures to be brighter thanks to overexposure.

The shape of the graph will tilt to the left if to little light enters the sensor leading to underexposure.

The shape of the graph will be convex in the center if the exposure is equal.



★Level :A function that helps pictures to align horizontally when shooting and to prevent tilting

to the one side.



★Automatic Focus (AF):The camera automatically sets focus to recognize the subject without any

additional settings. With the automatic focus adjustment, even rst timers can vividly capture a fast

moving subject.

★Manual Focus (MF):There are cases when the camera will focus on the wrong subject.

When having various subjects, MF function allows users to stage a photo as they wish by letting them

adjust the focus manually.

What it means to have an F1.8 Lens for G4?

F1.8 lenses of DSLR lenses, receive the most attention even among professional

photographers because of their excellent expression when shooting portraits.

F value (=aperture) is a numerical value indicating the brightness of camera lenses.

When having a lower value, it will increase the amount of light passing through;

therefore, you can get a clear and bright picture even at night, or indoors with less

light. The G4 smartphone is equipped with an F1.8 Lens for the rst time which

means you can take a picture of shining stars and the beautiful night sky, instantly

capture the blowing out of birthday candles and other beautiful moments with

exceptional quality. With G4’s brightest F1.8Lens, create your own world you wish

to see in brighter way. LG G4General Smartphone

LESSON 4

Are you familiar with the position of each button and its use? Master the most important functions of ISO / Shutter

Speed / WB / Exposure Adjustment before taking a photo! You will take amazing photos without realizing it!

Master ISO / Shutter Speed / WB / Exposure Adjustment

Sensitivity (ISO)is the extent to which the sensors respond to light represented by a number. It is indicated as 50, 100, 200, 400,

and 800. Each number represents light sensitivity. This means each value is twice as sensitive as the previous value. Raising the

sensitivity in the dark will increase the chance of taking a picture without blur (recommend raising the sensitivity even in broad

daylight.)The higher the ISO, the brighter the picture will be because of the quantity of light let in. However, there is a drawback of

decreased clarity because of more noise in the picture. Conversely, with lower ISO, the picture becomes darker but clarity increases.

Set about 100~200 ISO when taking a photo at night or when it's dark indoors and 400 ISO would be good with general scenery.

ISO

With lower ISO (ISO 100)–Smooth and clean without noise With Higher ISO (ISO 12800)– No blurring of subject but has rough and indenite colors

When taking a photograph 1. You can produce a smooth photograph without the noise by setting the ISO to a lower level

2. You can produce a clear photograph without shake by setting the shutter speed as a priority.

genius Oh's Tip

Shutter Speed means adjusting the amount of light let in when the shutter opens and closes. With a faster shutter speed,

less light is let in and sharper photos are produced but at times they can be dark. Conversely, with a slower shutter speed,

more light is let in, leaving an afterimage of the subject. You can also shoot different styles of long exposure.

Shutter Speed

Slow shutter speed |1/60s Fast shutter speed |1/6500s

White Balance is the technology that allows the camera to recognize natural color as we see it. Our eyes recognize the same

white paper under uorescent lighting or incandescent lamps; however, a camera is different to our eyes. In order to properly

represent true white colors, it needs to set the color temperature. However, if you apply it conversely you can produce a variety of

colors without using specialized programs like Photoshop.

Taking photos with lower WB values under incandescent lamps It is possible to produce a different atmosphere of color,

almost as if it were taken under sunlight with an increase in WB.

You can save pictures in RAW format to be corrected later.

If you touch , DNG will be generated with JPG when shooting.

Big storage space could be needed if you save in RAW format.

format. DNG also will be deleted once you erase the picture

from the gallery and you can only erase DNG from the File

Manager or PC.

Exposure Adjustment

Exposure is a function to adjust the amount of light exposed to the image sensor. Exposure is affected by both the shutter speed

and the aperture. Aperture controls the amount of light received at once and the shutter speed controls the amount of light overall

by adjusting the time of exposure. Besides this, exposure is also affected by ISO (sensitivity). In other words, you have to utilize the

aperture, shutter speed, and ISO in order to adjust the exposure. In the case of over exposure, the sensor receives too much light

resulting in the brightening of pictures. Conversely, in the case of under exposure, the sensor receives too little light resulting in the

darkening of pictures. By using G4’s exposure adjustment function, you can take a picture as you intend to, with true-to-life quality.

Under exposure (-2)Optimum level (0)Over exposure (+2)

It has more light and color information compared to

JPG les it can be changed to JPG through

exposure, white balance, and various modications.

The most popularly used image le format that can

be shared quickly on PCs or printers because of its

compatibility and small size compared to picture quality.

RAW

★

Save as RAW format

The word "RAW", as you can already induce from the word itself; is a le format that is stored without

processing. If you compare it to cooking, a JPG would be processed food that has been rened to suit the

needs of the public which limits the taste that can be produced by a chef. On the other side, a RAW would be

fresh ingredients that have the advantage to allow for the creation of taste without restrictions.

In the case of having to take a picture with low light, set the exposure value to +, when there is excessive brightness, set the exposure value to -.

genius Oh's Comment

In order to capture the longer trail of the plain, I decreased the ISO and set the shutter speed to 30 seconds. With a low shutter speed,

the long exposure of 30 seconds captures the trail of the plane. F1.8 |ISO 50 |Shutter Speed 30s |WB 2800K

★ A part of pictures were set as a Manual Mode and

were taken by ISO 50 to produce a clear quality with less noise

Shoot your daily life with Manual Mode using features such as ISO / White Balance / Shutter Speed / Focus

and set them as you desire. Get started by shooting with each function and along each step. Once you fully

understand the various settings try manipulating them in various ways.

Create memorable moments with Manual Mode!

genius Oh's Comment

The exquisite tones and color of this

landscape were achieved through the

use of a brighter exposure and by setting

the white balance to 5500K since it is in

direct sunlight.
