Mobile phone has long become a sharp weapon of photography, and now the functions of smartphone photography are good, especially in recent years, the flagship machine has made great breakthroughs in photography technology.

But if you don't know the function of your mobile phone, you will simply press the shutter when you take a picture. Isn't it a pity that it is so versatile?

Different brands of mobile phones, professional mode layout, name will be slightly different, but the usage principle is the same, can be integrated.

Mobile phone professional mode

After turning on the professional mode in the mobile camera, what comes into view is this interface, which has a lot of options to adjust.

The photometric phase will first detect the brightness of the external environment and calculate a reasonable amount of light input to ensure that the brightness of the photometric area is normal after the photo is taken.

Click on the screen is "focus", long press the screen "metering", the general focus of the default is also the metering point. Long press and drag behind the screen to move the metering position (which is also changed to "point metering" mode by default).

In different photometric modes, the phase will select different areas for photometry.

Matrix photometry: photometry of a wide area of the picture

Central focus photometry: the whole picture is measured, but the maximum proportion is allocated to the central area.

Point photometry: measure about 2.5% of the light around the light metering point of the picture.

02 ISO sensitivity can be understood as the sensitivity of the camera to light. When the sensitivity is high, only a little light can take a picture with high brightness.

If the light is very dark at night, it is often necessary to increase the sensitivity, otherwise the picture will be pitch black.

But the higher the sensitivity of ISO, the more noise of the picture, the sharpness and color of the picture will be interfered to a certain extent.

When taking pictures, you can set it to A / Auto / automatic, and the phone will automatically select a reasonable sensitivity value according to the photometric results.

The 03 S shutter can be simply understood as the time it takes for the camera to take pictures. For example, if the shutter is 5 seconds, then when you press the shoot button, it will take the camera 5 seconds to take the picture. The shutter time during the day is often from a few hundredths of a second to a thousandth of a second, which is very short, so you can't detect the length of the photo.

The longer the photo is taken, the more light will flow into the camera, the brighter the light will be, and the brighter the picture will be. When the light is dark at night, the shutter time will be longer.

▲ high iso long shutter increases the amount of light input to shoot the starry sky, but the picture is easy to blur when the shutter time is long. For example, the shutter time is 5 seconds. If the person moves in 5 seconds, you will get confused. When the light is dim at night, the shutter time becomes longer, and it will be patted after moving. If necessary, you need to use a tripod to keep the phone still.

▲ extended shutter recording fireworks track usually when taking pictures, set it to A / Auto / automatic, the phone will automatically select a reasonable shutter value according to the photometric results.

04 EV exposure compensation is used to change the camera's recommended exposure value to make the photo brighter or darker. It controls the exposure by changing the S shutter and ISO sensitivity. Can only be used when S and ISO are all automatic. When set to a fixed value, the EV exposure compensation cannot be used.

The focus mode supports single autofocus (AF-S), continuous autofocus (AF-C) and manual focusing (MF).

Continuous autofocus: when the viewfinder picture changes greatly, the phase will automatically focus again.

Single autofocus: the camera will automatically focus once, and then don't change it.

Manual focus: you control the distance of focus, from the nearest to infinity.

▲ slides closer to focus on the left and farther on the right 06 WB white balance light is also colored. If I want to shoot a piece of white paper, it will be yellow in the yellow light and blue in the blue light. At this point, the camera will use the white balance to adjust the color difference to make sure that the white paper is white.

White balance provides many modes that correspond to the colors of common lights. White balance also provides manual mode, white balance value small color is blue, large value is red.

White balance ensures that the imaging color is not affected by the color of the light source. You can choose the appropriate white balance or custom white balance according to the type of light source. In general, we can choose AWB (automatic White balance).

▲ adjusts the white balance to make the color more rich to sum up: when dealing with ordinary shooting scenes, we can directly use automatic photo mode, without the need to use professional mode. In the face of a special environment, or when you want to shoot a special subject matter, professional mode will be used.
