Master photographer, by the way, how did you take this high-brightness photo without overexposure? How do I take very dark photos?

You must measure the light incorrectly. You must be aiming at a dark place to measure light. The light source in the first picture is obviously not soft. It is recommended not to measure light under normal illumination, but to adjust to AV mode to evaluate light measurement. You can also focus with the viewfinder. The advantage of the viewfinder is that you can freely choose the metering part after focusing and measure the light in different places many times. I believe you will find a balance.
