Camerabag: Turn Your iPhone into a Vintage Camera
There's something special about the artsy quality of a vintage photo. Toy cameras such as Holga, Lomo and Diana are my favorite, but I'm a sucker for just about any cheap camera with a "temperamental" streak. Get from a vintage look for your photos without having to carry around an extra camera.
