What unique photography skills should we know in hot summer?

With telephoto, the focusing speed should be fast, preferably the original cow head. The aperture should be large, preferably with anti-shake. Suitable for long-distance capture. Wide-angle and ultra-wide-angle, the lens is facing other places, but it can be unconsciously brought into view without being discovered by the other side. If you want to shoot smoothly, you must take the initiative to show your intentions, get the recognition of the other party, and communicate more, so as to shoot a good film.
