backdrop

A backdrop is an image or set that appears behind people or objects when they are being photographed or filmed. It's usually something like a large picture, fabric, or even a real environment.

In movies and photoshoots, you often see a backdrop being used to create a specific atmosphere or mood. For example, if someone is taking a selfie in front of a bright blue screen with fluffy white clouds, that's the backdrop. It helps set the scene and makes the photo look more interesting. Sometimes, backdrops are even designed to look like real places, like city streets or beautiful landscapes. They can also be used in presentations or exhibitions to add some visual appeal to the display.
