PopBooth is a free iPhone app that simulates the experience of taking a quick series of photos (often goofy looking) in a photo booth. It takes four photos using the iPhone 4′s front-facing camera and then lets you apply one of five filters (normal, black & white, colorz, 1985 and hipster).

The photo strips can be shared via Facebook or email. However, the real interesting twist is that you can also have Sincerely Inc. (PopBooth’s developer) print and ship two sets of the strips to you. It can also ship a photo strip to anywhere in the world for $2.99.

Purchases are not available as in-app purchases because, as Sincerely Inc. notes, Apple currently prohibits in-app payments for physical goods
