Advantages include highlighting the theme and creating an atmosphere. The disadvantage is that it is monotonous and requires technology.

1, highlighting the theme: When shooting medical beauty products or surgical procedures, the black background can make the details of the products or operations clearer and highlight the theme.

2. Create an atmosphere: When shooting high-end medical beauty projects, the black background can make the whole picture more atmospheric and high-end, making people take these projects more seriously.

3, appear monotonous: Although the black background can highlight the theme, if it is not used properly, it will make the whole picture appear monotonous and lack vitality.
