Basic knowledge and skills of mobile phone photography

The basic knowledge and skills of mobile phone photography, we should all like taking pictures, but we should also pay attention to a lot of knowledge about photography, because there are many kinds of photographic equipment, and the most common one should be mobile phones. The following are the basic knowledge and skills of mobile phone photography.

Basic knowledge and skills of mobile phone photography 1 1. Master light and mode adjustment.

Anyone who has a certain knowledge of photography knows that light is an important factor affecting the imaging quality. Mobile phone cameras, like cameras, have high requirements for light. Therefore, if you want to shoot a good work, you must choose good lighting conditions and try to avoid shooting in the back light. Some mobile phones can meet the light source through external conditions, and can also be adjusted through the built-in auxiliary functions of the mobile phone:

1, adjust the brightness. Many mobile phones can adjust the brightness of the camera and can be used when the light is insufficient.

2. Night mode. It can be used not only at night, but also in night mode in case of insufficient light during the day to obtain better brightness. It's just that it takes a long time to take a picture after turning on this mode. If your hands shake slightly, the photos you take will have double images.

Step 3 flash. The flash on the mobile phone is actually a bright LED light, which can effectively fill the light when turned on, but the effective distance is relatively short, which is suitable for close-up shooting.

Second, coordinate hand holding and shooting posture.

Users who like to take photos with their mobile phones may be impressed. The camera phone is only that big and weighs less than half of the ordinary traditional camera. If you are not steady when shooting, even the best light will be ugly. In particular, CMOS cameras are more sensitive, and slight vibration will directly affect the imaging effect. When shooting, the right hand holds the camera at the subject, and then the left hand holds the right hand to keep it stable.

Because the response speed of the mobile phone is not as fast as that of the camera, it is not taken immediately after the camera shutter is pressed, but only when the shutter sound rings, so it is best to set the shutter sound when taking pictures, and the mobile phone must be held firmly when taking pictures. Especially when you press the camera function key, if you move at this time, the picture you take may be blurred, so you must keep a steady posture until you take a picture.

Third, pay attention to the parallelism between the mobile phone and the scenery.

If your photography skills are not good enough, and you haven't reached the level of freely using the perspective, you must pay attention to the parallelism between the mobile phone and the scene when shooting, that is, the plane where the mobile phone is located should be parallel to the plane where the scene is located, especially when shooting beautiful MM. If you don't master it well, the portrait will be easily deformed.

Fourth, your brainwave.

In fact, many good photos come from a flash in my mind. Nowadays, the camera phone is more and more powerful in the use of shooting function, with various styles of shooting effects and strange photo frames. You can give full play to your imagination and skillfully combine various functions. Perhaps your photos are not only different, but also rare creative works.

Basic knowledge and skills of mobile phone photography 2 1. If you want to shoot a big movie with your mobile phone, you must first learn to control the light and dark effect of the photo.

In professional cameras, we all know that the light and dark effects and details of photos are affected by aperture, shutter and sensitivity. But there is no aperture on the mobile phone, so many partners who have played with the camera always feel unprofessional when taking pictures with their mobile phones. In fact, this is just an illusion. Even if the mobile phone can't adjust the aperture to affect the brightness of the photo, we can adjust the shooting angle and direction, and adjust the shutter speed and sensitivity.

In addition, there is a better function in the mobile phone, which is exposure compensation. When the photo is underexposed or overexposed, we don't have to adjust the shutter and sensitivity. As long as the exposure compensation is adjusted relatively, more details can be obtained. Then the most basic basis for accurate exposure is that the details of the light and dark parts in the photo are good, and the color and effect are close to what we can see with the naked eye.

2. So how to avoid the problem of dull photos when using mobile phones for photography creation?

Due to the camera function of the mobile phone itself, the brightness of the photos is often slightly dim when we take pictures. In fact, this problem is also very easy to solve. We can use the exposure compensation in the mobile phone camera to solve the problem. After the camera of the mobile phone automatically measures the visible area, we can manually click on the focus and metering point area on the screen, and then slide the small sun (exposure compensation) sign on the side to solve the problem.

You can also adjust the parameters in professional mode, such as reducing the shutter speed. Another way to brighten photos is to use post-processing software to adjust them, which is also a good choice.

Some partners will ask, why not brighten the photos directly by increasing ISO sensitivity? The answer is simple. Upgrading ISO directly will cause more noise in photos, which will lead to a decrease in photo quality. Mobile phones are poor in tolerance and noise reduction, so it is not recommended to use ISO sensitivity directly to brighten photos.

3, the picture quality mentioned above, how to take pictures with a mobile phone to make the picture quality better.

In fact, this problem is also very easy to handle, which can be roughly divided into the following three methods:

The first point is to turn on the high-quality shooting mode to ensure the stability of the mobile phone. The more stable the phone, the better the picture quality and the clearer the photos.

Second, make the exposure accurate, ensure that all details are photographed as much as possible and use low ISO parameter values, such as ISO100; ; Try not to raise the dark part of the photo or lower the bright part of the photo later. Therefore, when shooting, we must ensure or look for a better lighting environment;

Third, you can start shooting in RAW format of mobile phones, then simulate the shooting mode of peripheral exposure in professional cameras, and then synthesize high-definition photos in later software, which can get good results.

Basic knowledge and skills of mobile phone photography III. Know mobile phones.

1, shooting function

If you want to play mobile phone photography, you can't conquer the world just by "normal mode". Different modes have completely different functions. If you want to shoot the effect that the subject highlights the blurred background, you have to use "portrait mode" or "large aperture mode".

If you want to shoot all the first-line river views or magnificent mountains and rivers, you have to use the "panoramic mode".

If you want to photograph the process of flowers blooming and falling, the sun and the moon change, and the situation changes, you have to use "time-lapse photography".

If you want to shoot beautiful atomized water, you have to use the "slow door" mode.

2. Basic terms

To learn mobile phone photography, you must understand these terms. Turn on the "professional mode" of the mobile phone to see the shutter speed (S), sensitivity (ISO) and exposure compensation (EV).

Shutter speed is the time from lens opening to lens closing. The shutter speed of moving objects will be fast or blurred, and the shutter speed of moving tracks will be slow or the tracks will not be visible.

Capture the moment of falling into the water

Sensitivity (ISO) refers to the sensitivity of a lens to light. Where the light is insufficient, the sensitivity should be appropriately increased, but not too high, otherwise there will be a lot of noise in the picture, and it is best to control it below 400.

There is too much noise in this painting.

Exposure compensation (EV) refers to the operation of manually brightening or dimming the picture. For example, when shooting a snow scene, the machine will think that the environment is brighter and will automatically reduce the exposure. At this time, it is necessary to artificially increase the exposure compensation, re-shoot, and restore the white of the snow.

Second, the classic composition

It is necessary to learn mobile phone photography and understand some composition methods, which can quickly improve your ability to control the picture, but don't be too obsessed with composition and master five or six common methods.

1, center point

This is a composition method that needs no study. Those who have never studied photography usually put the subject in the middle of the picture to shoot, but even if they have learned photography, this is still a common composition method, because the central point is the visual center.

2, the three-point line.

It is to put some objects and dividing lines on the three-point line of the picture instead of the two-point line, giving people a rigid and uncomfortable visual experience.

The horizon is on the horizontal bisector.

3. Jiugongge composition

Jiugongge composition refers to placing the visual point on the four points formed by the intersection of the horizontal and perpendicular bisector, which are the golden section points in a rough position. As we all know, the golden section is the most beautiful section in mathematics.

4. Symmetry

Symmetrical objects always give people a stable and balanced aesthetic feeling. Symmetrical composition is to present this kind of aesthetic feeling, and we can consciously look for symmetry, such as the symmetry of the building itself, the symmetry of the reflection in the water and the physical object.

5. Curve

Curves give people a smart visual experience and can guide the line of sight. Orientals are born to appreciate the beauty of curves, while European and American countries are more sensitive to straightforward lines. Curve composition is to take some curved objects into the picture, such as curved rivers, winding roads, curved coastlines and so on.

Third, capture light and shadow.

Photographers often say that "photography is the art of light and shadow". Indeed, many excellent works have the participation of light and shadow, and photos without light and shadow always feel something is missing.

1, pure light and shadow

One is to directly take "light and shadow" as the shooting object, that is, to simply and purely express light and shadow without too much other consideration.

2, light and shadow accessories

A kind of light and shadow exists in the form of "auxiliary material", that is, it has a clear subject, and it is added to make the picture more vivid and layered.
