One of the neatest tricks you can do with a standalone camera is the long exposure trick. You may have seen it used to turn the tail-lights of a car into long streaks of red curving through the dark behind a ghostly car, or to blur turbulent waters into a peaceful, misty-looking lake. In a regular camera, you have to finagle the shutter speed to get the level of blur just right, and there’s no second chance. On the iPhone, it’s way easier.
