A photo booth is a small, self-contained unit that allows people to take photographs, usually in a fun and casual setting. These booths often have a camera, a printer, and a touchscreen interface for users to control the photo-taking process. They are commonly found at events like weddings, parties, and fairs, providing guests with instant keepsakes. Modern photo booths may offer various features, such as digital props, filters, and the ability to share images on social media. Some booths are designed to accommodate groups, making them a popular choice for capturing memories with friends and family during celebrations.
