There are photo booths at Disney Parks available in multiple locations to take candid pictures of you and your friend/sister/cousin/mom. You can choose to pay $5 to print your pictures or you can add them for free to your Memory Maker account by scanning your MagicBand.
When you sit in the booth, begin by scanning your MagicBand. Follow the prompts on the screen to take 4 pictures of yourself and a companion. At the end, you can choose for the pictures to be stored in your account or you can print them as well.
We played around in the photo booth at the exit of Primeval Whirl. It was great fun!
Also find at Magic Kingdom and Disney Springs.
