How to adjust the picture of 6220c?

The close-up should be adjusted to macro.

After all, mobile phones are mobile phones, so mobile phones have their limitations.

(1), let's talk about the points for attention in mobile phone photography:

1. Catch the light

At present, mobile phones range from 30-800w pixels. 3 million is basically the same as DC. But be careful. Most of the lenses used in mobile phone photography are CMOS lenses, not CCD lenses. Because their photosensitive materials are different, their effects are also different. The camera lens of the mobile phone is also small. This further affects the shooting effect. Some friends will find out. When the light is not very good, the automatic state of the digital camera is to turn on the flash. So is the mobile phone. Try not to use backlight when the light is insufficient. If you must shoot like this, you can use the auxiliary light source to turn on the indoor light.

Step 2 grasp the distance

At present, the digital zoom of mobile phones has also made a great breakthrough. For example, the 6220c I'm using now has a digital zoom of 20 times, but it doesn't support optical zoom (only n93i in Nokia has optical zoom). Digital zoom is just to make things look bigger on the screen. But be careful. If you watch it on the computer, you will see a lot of impatience. There is a law in photography that even professional photographers abide by-if you want to shoot more clearly, you must keep the lens close to the subject. When you shoot something with your mobile phone. If you want to take a clear picture. You can approach slowly, approach. Then see the effect.

3. shooting positions

Mobile phones are generally small and can be operated with one hand. Every day when I watch people shoot. I found that many people clap with only one hand. So the photos they took can be viewed on the mobile phone. But when I watch it on the computer, I will be shocked. Correct posture, hold the shutter with one hand. Hold the other side of the phone with one hand. Hold your breath when you press the shutter, hold it steady, and a photo will be taken.

Step 5 stay after shooting

A mobile phone is a mobile phone after all. It doesn't have the processing speed of the camera (the exposure time is also very fast). So, after the shooting, stay for 2-3 seconds. So the photo was formed.

② noun description

First, choose a scene.

6220C has built-in automatic, custom, macro mode, portrait and other scene modes to assist users in shooting. When the user calls the corresponding scene mode, the camera will automatically set metering mode, focusing mode and shutter speed, which is helpful to improve the shooting success rate.

Second, the setting of white balance.

White balance control is to make the color of photos taken under various light conditions completely consistent with the color of the scenery seen by human eyes through image adjustment.

Simply put, white balance is a function that defines "white" as "white" regardless of the ambient light. Color is essentially an explanation of light. What looks white in normal light may not look white in dark light, and "white" under fluorescent light is also "non-white". If the white balance can be adjusted for all this, other colors based on "white" can be correctly restored in the obtained photos. At present, most commercial digital cameras provide white balance adjustment function. As mentioned above, the white balance is closely related to the surrounding light, so the use of the flash will be restricted when the white balance function is started, otherwise the change of ambient light will invalidate the white balance or interfere with the normal white balance.

For digital cameras, although you can adjust the white balance in the image processing software, if you are unfamiliar with the image software or don't want to bother to adjust it, you'd better choose a digital camera with better white balance function.

The 6220C camera has both automatic white balance and manual white balance. But even if it is done automatically, its error correction ability is limited. According to the actual shooting, you can choose "sunny, cloudy, incandescent and fluorescent" four modes to improve the shooting effect.

Third, exposure compensation

Exposure compensation is also an exposure control method, which can keep 6220C within 2. If the ambient light source is dark, you can increase the exposure value (for example, adjust it to+1EV, +2EV) to highlight the clarity of the picture.

In the process of digital camera shooting, if you press the half shutter, a picture similar to the final effect will be displayed on the LCD screen, and all focusing and exposure will start. The exposure at this time is the exposure of the final picture. If the picture is obviously bright or dark, it means that the automatic metering accuracy of the camera has a big deviation, and exposure compensation should be forced, but sometimes the brightness displayed during shooting is different from the actual shooting result. Digital camera can browse the picture immediately after shooting, and at this time, you can see the brightness of the shot picture more accurately, and there will be no discrepancy. If the shooting result is obviously bright or dark, it is necessary to shoot again and force exposure compensation.

When the shooting environment is dark and it is necessary to increase the brightness, and the flash can't work, exposure compensation can be carried out to increase the exposure appropriately. When making exposure compensation, if the photo is too dark, the EV value should be increased. Every time the EV value increases, it is 1.0, which is equivalent to doubling the light input. If the photo is too bright, the EV value should be reduced. Every time the EV value is reduced, it is equivalent to doubling the amount of light entering. The compensation interval of 6220C is adjusted in units of 1/2(0.5).

When the photographed white object looks gray or not white enough in the photo, it is necessary to increase the exposure, which simply means "the whiter the more". This seems to run counter to the basic principles and habits of exposure, but it is not. This is because the camera's photometry often focuses on the central subject, and the white subject will make the camera mistakenly think that the environment is very bright, so it is underexposed, which is also a common problem that most beginners are prone to make.

Because the shutter time or aperture size of the camera is limited, it is impossible to reach the adjustment range of 2EV all the time, so exposure compensation is not omnipotent, and it is still possible to underexpose in too dark environment. At this time, it is necessary to consider matching the flash or increasing the ISO sensitivity of the camera to improve the brightness of the picture.

Generally speaking, a negative with rich layering can be called correct exposure. Most modern cameras have the function of internal metering. In most cases, shooting according to the data provided by the exposure meter can make most negatives get basically correct exposure. This is because the exposure meter reads 65,438+08% gray tone, and 65,438+08% gray is the average light value in our daily life scenes, such as our skin color. However, the correct exposure is not equal to the best exposure, especially when white or bright objects are dominant in the picture, there will be obvious deviation if shooting only according to the photometric data of the camera, that is to say, the white objects, bright objects and dark objects in the picture are all 18% gray scale, which is naturally unsatisfactory. Therefore, exposure compensation plays an extremely important role in the absence of incident exposure meter or gray board. Our common cameras with automatic exposure function generally have exposure compensation function, while cameras with manual exposure need to compensate exposure by controlling shutter and aperture. From the picture below, we can see the results of different exposures of white objects and black objects.

Increase exposure

According to the white tea set, photometric exposure, the main body of the picture is gloomy.

The main color tone is improved by adding 0.5EV (half stop) exposure on the basis of the original metering.

Based on the original photometry, the exposure of 1EV is increased (1), which correctly represents the white subject.

Reduce exposure

Photometry and exposure are carried out according to the black subject, and the tone of the black subject is light.

On the basis of the original photometry, the exposure of 0.5EV (half stop) is reduced, and the color tone of the black subject is improved.

On the basis of the original photometry, the exposure of 1EV( 1) is reduced, and the black color of the subject is correctly represented.

Some experienced photographers often use the word "white plus black minus" to explain the essentials of exposure compensation. Because of the different reflectivity of various scenes, there is no specific standard for the compensation range. Therefore, photographers should form the habit of carefully observing the scene, analyzing the balance and reflectivity between black, white and gray, grasping the exposure essentials they need from thinking and practice, and shooting wonderful works. Fourth, sharpness (sharpening degree)

Sharpness, sometimes called "sharpness", is an index that reflects the plane sharpness and edge sharpness of an image.

If the definition is increased, the detail contrast on the image plane is also higher and looks clearer. For example, in the case of high definition, not only the wrinkles and spots on the face on the screen are clearer, but also the protrusions or depressions of facial muscles can be lifelike. On the other hand, dark lines or black lines in the vertical direction, or places where black-and-white images suddenly change, in the case of high sharpness, the edges of lines or black-and-white images suddenly change more sharply, and the overall picture appears clearer. Therefore, improving sharpness is actually improving clarity, which is the good side that people need.

However, the higher the definition, the better. If the sharpness is adjusted too high, white lines will appear on both sides of the black line, and the image will look distorted and dazzling. If this happens on a block image, the image will be seriously distorted and ugly. For example, when this happens on a small face image, not only the edges of the face will have white edges, but also the edges of black and shadow parts such as hairline, eyebrows, eyes, nose and lips will have white edges, which looks very uncomfortable. It can be seen that although the sharpness is too high, it will improve the clarity, but it will also make the graphics out of shape, which is also not a good thing. Therefore, in order to obtain a relatively clear and true image, the sharpness should be adjusted appropriately.

Comparison of verbs (abbreviation of verb)

Contrast is a measure of the different brightness levels between the brightest white and the darkest black in an image. The larger the difference range, the greater the contrast. The smaller the difference range, the smaller the contrast. The good contrast ratio of 120: 1 can easily display vivid and rich colors. When the contrast ratio is as high as 300: 1, all levels of colors can be supported. However, contrast and brightness face the same dilemma. At present, there is no effective and fair standard to measure contrast, so the best way to identify it depends on the eyes of users.

Generally speaking, the greater the contrast, the clearer and more striking the image, and the brighter and more colorful the color. And the contrast is small, which will make the whole picture gloomy. Contrast is very helpful for image clarity, detail expression and gray level expression.

Sixth, sensitivity.

ISO sensitivity is an indicator of light sensitivity. The higher the sensitivity, the more sensitive to light. Generally speaking, the higher the sensitivity, the better the effect when shooting moving objects or low light. However, at high sensitivity, there are more noise signals in the image, and the definition is also reduced. On the contrary, at low sensitivity, the image noise signal is reduced and the image quality is better, but it is not suitable for shooting moving objects or low light environment.

Many players often encounter the following situations: shooting in places where flash is forbidden, such as exhibition halls, we have to use flash, and the result is blurred photos. If the flash is used, the subject will reflect light and affect the picture. The same thing can happen indoors or in dark places.

An easy way to take good photos without using flash is to adjust ISO. Of course, if the ISO setting is improved, the graininess of photos will be more serious, which requires users to master flexibly according to the situation at that time. For example, our 6220C has high, medium and low ISO sensitivity. High sensitivity value is suitable for dim places, but it will lose the vividness and naturalness of colors. Special reminder is to prevent hand shaking in dark places, because the shutter of 6220C cannot be adjusted quickly.

PS: set the macro to the highest level.

Here, taking the most troublesome night shooting as an example, we will explain in detail how to set up our big 6.

First, the characteristics of night photography

1, the subject is prominent and the theme is distinct.

Night photography, because the sky is dark, some unnecessary or even destructive scenes are covered by darkness, and the main part of the subject or scene is highlighted with appropriate lighting because of the need of shooting, giving people a vivid impression. For example, when shooting a construction site, it is difficult to avoid some messy deposits or dilapidated sheds in the daytime, but at night, most of these things are hidden in the dark, but the subject is easily highlighted by the light. It can be seen that night photography has the characteristics of prominent subject and distinct theme. 2. Exaggerate the scenery and render the atmosphere

Landscape photography, because of its unique shooting method and tone processing technique, has the specialty of exaggerating scenery and rendering atmosphere. It can use light to create a tone, exaggerate the scenery, make them more prominent than the real scenery, and have a strong appeal. In addition, it can also use special shooting technology, make full use of the characteristics of the surrounding environment and render it reasonably, so that the atmosphere of the shooting scene is very strong.

For example, shooting the train station during the day, the picture is not lively, there are not many trains, and the atmosphere is not strong. If you shoot at night, you can use the method of multiple exposures to open the shutter every time the train comes, so that bright locomotive lights can stay on the picture, thus obtaining the busy effect of train operation.

There are many light sources with dual functions.

Night photography often has many light sources at the same time, which is different from daytime photography. Such as lights, flames, moonlight or the afterglow of sunset. It plays a dual role in night photography: it is not only the light source of illumination, but also an indispensable part of the picture. If there is no light, fire or moonlight in night photography, the atmosphere of night photography will be greatly weakened.

4. The theme is still life.

When shooting at night, the subject is mainly static scenery, which is generally not suitable for shooting fast-moving objects. Due to the weak light at night, the illumination of various scenes is very low, and it takes a long exposure time when shooting. In addition, the contrast of night light is very strong, and there is a great difference between bright and dark places. If rapid exposure is used, the negative film is underexposed, the picture level is reduced, and the photo lacks charm.

Second, the matters needing attention in night photography

1, to prevent the camera from moving.

When shooting at night, the camera should be placed in a stable and firm place. When setting, pressing the shutter and observing the scenery, don't touch the fuselage, otherwise the negative film will appear ghosting and the shooting will fail.

2. Determination of distance

The shooting distance should be measured as accurately as possible, otherwise it will directly affect the clarity of the scene. Generally speaking, when shooting a big scene at night, the distance can be placed at infinity. If you take a shot or close-up, you should focus on it. The clearer the focus, the better. The focus should be fixed on the position of the subject or the main part of the scene, and then measured after being illuminated by a flashlight. You can also use bright spots near the subject instead of measurement. Once the distance is determined, it cannot be changed at will during shooting.

3, white balance adjustment

Choosing different white balance will directly affect the tone and artistic conception of the photo. Generally speaking, don't choose automatic white balance, which will affect the inherent color of light and make it lose its unique color temperature feeling. In order to highlight the brighter colors of lanterns, you can set the white balance to "sunshine" mode. Of course, this is not absolute. You can try shooting with a different white balance and make adjustments later.

4. Other preventive measures

There are some precautions for night shooting. It is not easy to choose high iso (sensitivity), which will produce noise, and generally choose low ISO; It is best not to use flash, which will destroy the atmosphere of the scene, and the general random flash will not play much role in night scene shooting; Stability is crucial. Press the shutter gently to avoid unnecessary vibration, and also pay attention to whether there is a vibration source at the scene.

The key is to practice more. A mobile phone is not a camera, but if you practice hard, you can get a very close effect to a digital camera.

Because of the nature of our work, we usually use cameras, so we must carry out pre-job training before taking up our posts. Then someone will ask me, why are you still studying mobile phones? In fact, this is very simple, because sometimes you can't buy a battery in the middle of nowhere. At this time, the camera is dead. What should I do? Then only the mobile phone continues. We are very strict with photos, so we will study the skills of taking photos with mobile phones.

In addition, this article quoted some contents on the Internet and some explanations added by myself.
