When shooting in professional mode, you can freely adjust parameters such as ISO sensitivity and focus mode.
1. Turn on the camera or enter more cameras (depending on your model), and then select professional mode.
2. You can set the following parameters:
Adjust metering mode: Click M to select metering mode.
Adjust ISO sensitivity: Click ISO and slide the ISO adjustment area.
When the light is weak, the ISO sensitivity can be improved; In the case of sufficient light, the ISO sensitivity can be reduced to avoid too much noise in the picture.
Adjust shutter speed: Click S to slide the shutter speed adjustment area.
Shutter speed will affect the amount of light entering the camera. When shooting static scenery and portraits, you can slow down the shutter speed. When shooting sports scenery and portraits, you can increase the shutter speed.
Adjust the exposure compensation value: click EV and slide the EV adjustment area.
When the light is weak, the EV value can be increased; When the light is strong, reduce the EV value.
Adjust focus: click AF to select focus mode.
Adjust hue: click WB to select white balance.
If you are in the daytime, you can choose the sun icon; In a cloudy or gloomy environment, select the rain icon.
Click the color temperature icon to change the color temperature to make the picture look colder or warmer.
Adjust the storage format: Professional mode provides you with JPG and original image format. Click the JPG icon at the top of the viewing box and select a different storage format.
RAW format photos retain more photo details, which is convenient for post-processing, but it takes up more storage space; Photos in JPG format occupy relatively small storage space, so you can choose according to your needs.
If the RAW format is selected, the mobile phone will automatically save a photo in normal format and a photo in RAW format when taking photos, and the photos in RAW format will be saved in the RAW album of the gallery.
Turn on the auto-focus auxiliary light: To focus in low light, click the auto-focus auxiliary light icon to turn on the auto-focus auxiliary light. 3. Click the shutter to take a photo.
What do the parameters on the digital camera mean?
1, pixel and resolution
Pixel is the most basic unit of digital camera image. Each pixel is a small point, and points of different colors and brightness are gathered together to form a photo. The higher the pixel, the higher the resolution and the larger the imaging size.
2. Optical zoom and digital zoom
Optical zoom is to enlarge and reduce the scene to be shot through the movement of the lens in the camera lens. The larger the optical zoom coefficient, the farther the scene is photographed. Digital zoom is similar to using software to enlarge a part of an image in a computer, that is to say, using photo editing software can achieve the same effect as digital zoom, so it is not necessary to consider its digital zoom ability when choosing a digital camera.
3. Common exposure modes
Program automatic exposure is an exposure mode in which the camera automatically sets the aperture size and shutter time according to scene brightness, CCD sensitivity and other information. Shutter priority is just the opposite of aperture priority, which is an exposure mode with manual shutter time and automatic aperture size.
4, wide-angle lens
Wide-angle lens, popularly speaking, is a lens with short focal length and wide viewing angle. A photo of the same size can accommodate a wider range of scenery and achieve a broader vision and magnificent artistic expression, generally referring to a lens with a focal length less than 35 mm
5, macro shooting function
Macro means to draw closer and farther to the subject. In this respect, the capabilities of various digital cameras vary greatly, and some can even take photos close to 1 cm, which is a good helper for people who often need to take very small objects at close range.
Extended data:
principle of operation
It integrates image information conversion, storage and transmission, and has the characteristics of digital access, interactive processing with computer and real-time shooting. Light enters the camera through a lens or lens group, and is converted into a digital signal through an imaging element of a digital camera, and the digital signal is stored in a storage device through an image operation chip.
The imaging element of digital camera is CCD or CMOS, which is characterized in that when light passes through it, it can be converted into electrical signals according to different light. Digital cameras first appeared in America. More than 20 years ago, the United States used it to transmit photos to the ground via satellite. Later, digital photography was converted to civilian use, and its application scope continued to expand.

Professional mode parameters of mobile phone camera:
Shutter: Turn on the camera professional mode, the letter S refers to the shutter time, and the shutter is the time when the external light enters the mobile phone. When ISO is fixed, the larger the shutter value, the brighter the picture, and the smaller the shutter value, the darker the picture.
Sensitivity: turn on the professional mode of the camera, and the sensitivity referred to as ISO refers to the sensitivity of the camera to light. When the shutter is constant, the larger the ISO value, the brighter the picture, and the smaller the ISO value, the darker the picture.
White balance: Turn on the camera professional mode, the letter WB stands for white balance, and AWB(AUTOWB) stands for automatic white balance, which can automatically restore the white in the picture. When the color temperature is constant, the smaller the value, the colder the picture; The larger the value, the warmer the picture.
Exposure compensation
Turn on the camera professional mode, and the letter EV stands for exposure compensation. Exposure compensation is a method to control exposure. Although it has the same effect of improving the brightness of the picture as ISO, there are still differences. Exposure compensation is mainly used for scenes with inaccurate camera metering.
Focus mode: Turn on the camera professional mode, and the letter AF stands for focus mode. Focusing methods are divided into automatic single focusing (AF-S), automatic continuous focusing (AF-C) and manual focusing (MF).

What are the parameters of Huawei's mobile phone professional camera mode? I know all the other parameters, but I don't know what parameters are in the diagram.
Huawei mobile phone professional camera modes include metering mode (M), sensitivity (ISO), shutter speed (S), exposure compensation (EV), focusing mode (AF) and white balance (WB).
The figure refers to the parameters of metering mode (M).
The specific parameters are as follows:
1, measurement mode (m)
There are three metering modes, namely matrix metering, center focusing metering and spot metering. Matrix photometry is used to measure the whole picture, which is suitable for shooting scenery. Central key photometry is used to measure the center of the picture and is suitable for taking portraits. Spot metering is suitable for scenes with obvious contrast between light and shade and complex light.
2. Sensitivity (ISO)
Sensitivity can control the sensitivity of the sensor to light. The ISO value can be raised when the picture light is weak, and it is suggested to lower the ISO value when the light is sufficient.
3. Shutter speed (seconds)
Indicates the length of time the camera is turned on in seconds. When shooting a still object, the shutter speed can be reduced, and when shooting a moving object, the shutter speed can be increased.
4. exposure compensation (EV)
Change the camera exposure parameters to darken or brighten the photos. Exposure value can be turned up when the light is dark, and exposure value can be turned down when the light is hard.
5. Focus mode (AF)
Wu stews shit to scare you, Cang Gou Naier _F-C_ Yuanyue stews shit to scare you, Shuo Naier _F_ nephew gets more and more stubborn, and you are satisfied.
6. White balance
It restores white objects through a camera. AWB is automatic white balance.
