How to avoid direct light on the face and avoid yin and yang faces when taking pictures?

1. Change the angle of the character (for example, head up or down to avoid direct angle).

2. Avoid bright light during this time (it's almost noon).

3. Fill the darkness with something like a reflector.

4. Turning down the aperture also has a little improvement effect, but it is not obvious.

5. Reduce exposure. But there will still be high contrast in the later stage, and it will be very troublesome in the later stage.

There are probably only these methods, and the first three are the fundamental solutions.
