About taking pictures at night.

The small bright spot is because the light of the flash is too concentrated, and the highlight formed by the reflection from the tip of the object overflows. This situation is very common when the fuselage comes with a flash and is used in a dark environment. There are two solutions: either use an external flash, or use a white translucent thing to slightly block the flash, so that the light of the flash is not so concentrated.

It is dark to shoot at night, which is the reason of insufficient light. The standard practice is to use a slow shutter+tripod+small aperture. A slow shutter is used to increase the luminous flux, and usually requires an exposure time of more than 5 seconds. The tripod tries to avoid the vibration of the camera when the shutter is slow. A small aperture is used to show the edge of the light source. If you find that the photo is shaking badly, the aperture can still be enlarged a little, and the iso can also be improved a little, but the charm of the night scene will be greatly reduced.
