The app Synthcam does a innovative approach on getting some real depth of field, normally ascociated with slr cameras. To achieve this, it’s combines real time tracking with multiple exposure. You lock the foreground to the tracking points, then move the iPhone in circles. The result is, the furter away, the more it moves, and the more blurry it becomes with a long shutter-type effect. The foreground is kept sharp trough the long exposure due to the stabilizer. This app requires some skills and practise, and a steady motive. But it’s the only one of its kind.
