I thought I'd seen iPhone camera capabilities stretched just about as far as they could go with add-on apps, but I was wrong. Focos for iOS does a bunch of interesting things, including real bokeh effects, focusing a photo after shooting it which mimics light field photography, and selective diaphragms to give you different bokeh spot effects and 3D lighting, far more powerful and sophisticated than what Apple provides. The app has been out for awhile, but continues to improve.
