My photography friend came in to teach me how to shoot night scenes.

Why did iso go upstairs? That will only increase the noise and affect the image quality.

1. If you have a tripod, you don't need to increase the iso value. It is best to keep iso to a minimum.

2. The aperture should be smaller (the larger the F value, the smaller the aperture) to make the picture more detailed.

3. It is better to have a remote control, which can reduce the vibration of the fuselage and make the picture clearer.

4. Determine the shutter speed according to the aperture size.
