How to shoot a good night scene and how to set parameters in general.

1, take Huawei mobile phone as an example. First, you need to click the camera application logo in your mobile phone, as shown in the figure below.

2. After entering the camera interface, click the sign indicated by the arrow above the shutter button.

3. Click the ISO logo in the pop-up menu. This parameter refers to the sensitivity of the camera. The higher the sensitivity, the shorter the exposure time, but the more noise in the picture.

4. Adjust the ISO parameter value column to the lowest value of 50 by sliding the screen left and right.

5, and then click the S symbol indicated by the arrow. This parameter is the shutter exposure time. The equipment must be kept still before the end of exposure time, otherwise the picture will be blurred.

6. Set the exposure time of the shutter to several seconds. If the second is too long, the hand-held posture cannot guarantee the stability of the mobile phone, so the quality of the photos taken will be blurred.

7. Hold the phone steady and shoot it at night, which is the effect of ISO when the parameter is set to 50 and S is 4.
