What are the shooting skills of Canon 450D? Especially at night?

Photography has no skills and relies on solid basic skills. Even if there are some skills, they are based on good photography skills. So I can't answer your question about photography skills. As for night photography, I can give you some basic suggestions:

1, use a tripod.

2, use low ISO.

3. Use cable release or self-timer mode.

4. Adopt manual mode to deal with complex lighting environment and realize accurate exposure.

5. Manual white balance is used to replace the automatic white balance that will go wrong at night.

In addition: Kengo only produces filters and 500mm folding lenses, and there is no such lens as 18-55mm.
