What size reflector is needed for portrait photography?

There are large and small reflectors, which need to be determined according to the shooting needs.

Outdoor multi-person full-body shooting: the circular reflector with a diameter of 0.8- 1. 1 m can basically meet various indoor and outdoor shooting needs.

Outdoor single-person full-body shooting: elliptical reflector with a diameter of 0.8 meters.

Outdoor single-person half-length or frontal shooting: 0.8 or 0.6 meter square boards, or boards that can reach this area after folding.
