What does the artist background picture mean?

The background used by artists when taking photos. As a public figure, artists need to take many different photos, so they need different background pictures to add to the background of the artist. Background pictures generally refer to the pictures in the visual image that correspond to the visual foreground that people see and serve to set off the foreground. An independent image that coordinates tones and other functions, and is generally used behind a flat or physical foreground with a far-reaching visual effect.
