This creative photography app from Lenka features filters that are above and beyond what you'll find on your favorite photo-sharing apps. Naturally, this comes with a price tag of $2.99, but what this will give you is a unique image processing software with automatic exposure.
The app was developed with the capabilities of the iPhone 5 in mind, although it can be used on any iPhone just as well. Rather than offering tons of fancy filters, the app only shoots in black and white and the only adjustments that you can make include adding contrast to the image. On top of this, the use of flash is disabled for this camera app, so there's no possibility of taking an embarrassingly bright shot or catching someone with red eyes.
