When you shoot in professional mode, you can freely adjust parameters such as ISO sensitivity and focus mode.

1. Open the camera or go to Camera > More (depending on your model) and select Professional mode.

2. You can set the following parameters: (1) Adjust the metering method: click M to select the metering method.

(2) Adjust ISO sensitivity: Click ISO and slide the ISO adjustment area.

When the light is weak, the ISO sensitivity can be increased; when the light is sufficient, the ISO sensitivity can be lowered to avoid excessive noise in the picture.

(3) Adjust shutter speed: Click S and slide the shutter speed adjustment area.

Shutter speed will affect the amount of light entering the camera. When shooting still landscapes and portraits, the shutter speed can be lowered; when shooting moving landscapes and portraits, the shutter speed can be higher.

(4) Adjust the exposure compensation value: click EV· and slide the EV adjustment area.

When the light is weak, you can increase the EV value; when the light is strong, decrease the EV value.

(5) Adjust focus: Click AF· to select the focus mode.

(6) Adjust the color tone: Click WB· and select white balance.

If you are in daylight, you can select the sun icon; if it is cloudy or dark, select the rain icon.

Click the color temperature icon to change the color temperature to give the screen a cooler or warmer tone.

(7) Adjust storage format: Professional mode provides you with two image formats: JPG and RAW.

Click the JPG icon at the top of the viewfinder to choose a different storage format.

Photos in RAW format retain more photo details, making it easier to post-process the photos, but take up more storage space; photos in JPG format take up relatively less storage space, so you can choose according to your needs.

If you select RAW format, your phone will automatically save one photo in normal format and one in RAW format when taking a photo. The RAW format photo will be saved in the RAW album in the gallery.

(8) Turn on the autofocus assist light: If you want to focus in a low-light environment, click the focus assist light icon to turn on the autofocus assist light.

3. Click the shutter to take a photo.
