It seems oxymoronic to discuss stylised photos and the iPad 2 in the same breath, but Camera Boost, the latest iOS photo app, wants to help with the lack of camera apps made especially for the iPad.
More than just an image effects app, Camera Boost offers up a life preview of multiple effects while you're taking a photo so you can decide which one looks best on the fly. And it will also enhance photos taken with the iPad 2, which helps compensate for the deficient camera found in the iPad 2. The app is $4, which isn't all that expensive, but is probably non-essential if you don't use your camera on a regular basis. [iTunes]
