A green screen photo booth employs a green backdrop that facilitates the removal of the green color during post-processing, allowing for the insertion of custom backgrounds into the images. Users pose in front of the green screen, and the photo booth software replaces the green background with a digital image or video of their choice, resulting in unique and customizable photos. Green screen photo booths are popular at events, parties, and promotional activities, offering an exciting and interactive way for guests to capture memorable moments with a personalized touch.
