PTA funds Sound System and Green screen

Green screens or blue screens are used as backdrops in chroma key photography, which is a process that replaces a solid-colored background from behind the subject of a photo (or video) with a new background. When you watch the weather forecaster on TV standing in front of a map, or Spiderman climbing down a building, you are seeing chroma key photography at work!
