The wedding scene and scene light are predictable, and the conversion is not particularly fast. The host, especially the bride, is very demanding about beauty. Therefore, the photos should be as bright as possible without exposure.
Personal experience is to control exposure by manual adjustment.
First, adjust the white balance to the light, and the color is a little warmer.
Second, the metering is changed to spot metering or central button metering to ensure that the owner can, generally placed in the center of the picture.
Third, the focus is changed to point focus, only for the owner.
Fourth, use the exposure reference scale to adjust the aperture and shutter speed. Generally, the telephoto end is used to control the depth of field, and one or several apertures (generally four for individuals) are selected according to the field light, then the shutter speed is adjusted, and exposure marks are shot to the right at 1 and 2.
My own opinion, explore slowly.
