How does Huawei mate30 shoot the moon?

Hello, Huawei mate30 needs to set the parameters: 1. Select a professional mode for the camera; 2.ISO is pulled to the lowest level; 3. The exposure compensation EV is set to 0; 4. Set the shutter time to the fastest; 5. Select 10 zoom; 6. Aim at the moon, control the mobile phone and wait for the focus to be completed; 7. After focusing, press the photo button quickly. So we can take a clearer picture of the moon. Of course, you can also turn on AI, then zoom in to 30 times, bring up the moon mode, and let AI finish shooting. But not as fulfilling as a professional model.
