Paper Camera is just plain fun. Plenty of photo apps let you apply filters after the fact, but this one performs its manipulative magic inside your camera, transforming your images in real-time before your dazzled eyes.
The filters are robust, offering a nice variety of cartoon- and painting-style choices to help make even the most uninteresting photographic situations colorful, graphic or both. And Paper Camera supports the same wacky filter set for videos you shoot.
We love the fact that the app saves both the original file and the filtered version to our library so we can do what we want with the original.
