What are the skills of shooting fireworks at night, and how to better adjust the shutter, aperture and sensitivity?

Be sure to use a tripod. You can prepare a thick black paper big enough to cover the lens. The aperture should be as small as possible and the shutter should be as slow as possible. The camera had better have a T-door and a B-door. Set ISO to 200 and manually focus and lock. Operating steps-1. After manual focus lock, block the lens with black paper. 2. Press the shutter in the middle of the fireworks, and take off the black paper for exposure when the fireworks are about to bloom. After the fireworks, the exposure is over (so the shutter speed is faster than that of a single fireworks). The role of black paper is to replace the shutter to open when shooting without worrying. In addition, the aperture can also control the imaging effect. Large aperture produces halo, and small aperture forms floodlight. When adjusting ISO, it also changes according to the situation. High ISO will produce noise, and long-term exposure to low ISO will also produce blue spots and red spots. I know. That's all. I hope it works for you.
