How does Nikon d750 shoot night scenes more sensitively?

Night scene shooting, the lower the iso, the better. The lower the iso, the purer the image quality.

It is most suitable for shooting night scenes with low sensitivity, slow door, small aperture, tripod and pay-off at the same time.

If you shoot the starry sky, it's another way to set it up … it's not the same as shooting ordinary night scenes.
