Help! Nikon d700 uses high light and dead white to shoot people, with great contrast. How to solve it?

Pay attention to the environment when shooting, and small and fresh shooting pictures are generally high-profile. The back of the first picture is black and incongruous, so you can choose to shoot the back of the character in reverse light. The second picture is dark, so it needs to be raised again in the later exposure, adjust the tone, and cut out the right third of the picture. The third problem of dress matching.
