Camera Noir is an ultra-simple iPhone app that includes everything needed to create striking, inky and rich black and white images, for just $2. It features only three buttons on the screen: the shutter, a button to browse your photo library, and the brightness button. This last is the only control you have over the image, and it comes in three flavors: lo, mid and hi. Despite the simplicity of the app, there is no compromise on the quality of the image, as it really uses all the information it gets from the iPhone’s camera. Download the app here.
