The Teams green screen effect allows people to select a uniform backdrop to apply effects upon using fewer system resources and achieving a cleaner output. Not everyone has a suitable backdrop, so I used the wall behind my desk to see what the Teams green screen effect could do with it. And although some imperfections resulted from the lack of uniformity for the wall, you can still see how this will be a useful feature. That is, if you use a proper backdrop!
