Inspired by Karen at Teen Librarian Toolbox, I started using a green screen at our last maker club. The kids and I had SO much fun. I wanted to share a little bit about what we did.
Our green screen set-up is available from Amazon and comes with black, white, and green backdrops. It's not professional quality but it works great for my purposes (green screen photography but we also use this setup to run photo booths at a number of our programs).
Like Karen, I loved the app Green Screen Wizard Mobile ($4.99 plus in-app purchases if you want to use some pre-made backgrounds) for its quick use. I was able to show the kids how to import backgrounds once and they totally ran with it. We only had one iPad at this program but we are in the process of getting more set up so I plan to have 2-3 at the next Maker Club program.
The kids really started getting into when I showed them how to drape the green screen to make my head appear to float in space, as you can see in this photo below:
