In the wedding shooting scene of the hotel, should the focus be on the central point or the central area or all areas be autofocused?

The key depends on what camera (including lens) you use. Because of the shallow depth of field, it is recommended to focus on a single point for a long lens SLR camera. Portable compact camera with smart focus can be used in full automatic mode. Remember, the wedding is mainly a record of the process, don't pursue any "blur effect", the greater the depth of field, the better. Generally speaking, "small aperture, short focal length and far focus" can realize a clear picture from far to near. In addition, the wedding held indoors is affected by lighting conditions, and there are certain requirements for the camera's high sense.

If you have a flash, and the flash index is large, then you can use 135 at close range, and the effect is basically not great at long distance. When using the header of 1.8, the flash can come in handy, for example, when the bride and groom take a photo to welcome guests, or when the bride and groom propose a toast to the guests. But the flash consumes a lot of power, so you should have enough batteries. (wed 1 14 answers for you)
