So, let me look at the image. The background is a solid green, typically used in chroma key compositing. The person is wearing a black dress with lace sleeves and lace details. The dress fits great and has lace on the sleeves and hem. The man had wavy hair and was wearing makeup. The green background is uniform, so probably a green screen setup.

The image shows a person standing in front of a solid green background, which is commonly used for chroma key (green screen) in video productions. The person was wearing a black dress with lace detailing on the sleeves and hem, and makeup. Green background unifies as a background for visual effects or editing.
Ultimately, the answer is \boxed{green screen background (or chroma key background)}.
