You may have seen the photo booths scattered around Disney World. There are a handful of photo booths that have the option to save the pictures to your magic band at no charge but to print them you will need to purchase either memory maker or pay for the photo. One of the benefits of adding the Memory Maker to your vacation package at Disney World is that you will get all your photo booth pictures as part of the price. Also if you have an annual pass you get all your photopass photos downloaded to your My Disney Experience account.
For the locations of the photo booths we have seen around Disney World check out the end of the post!
Just scan your magic band or your photopass card and then take your pictures like normal. 
At the end of the session you will have to the option to purchase your pictures or only have them saved to your photopass. 
The pictures will show up in a set of 3 like these. This is a fun souvenir and kids will love taking silly pictures. 
These were taken at the photo booth in the gift shop inside Journey into the Imagination at Epcot.
Other locations we have seen photopass enabled photo booths:
- gift shop outside of Space Mountain at Magic Kingdom
- In Dinoland near Primeval Whirl at Animal Kingdom
- on the boardwalk at the Boardwalk resort
While you can find photo booths in most of the resort arcade these are not equipped to link to your photopass yet.
