I'm a camera snob, I'll admit it. That's why I shoot mostly film.On the other hand, I do enjoy shooting with the iPhone for the superior ergonomics. The ultimate point and shoot.
However, every article or argument on the merits of phone photography fails to mention that which I feel is the biggest drawback - all automatic controls.You can't control shutter speed or aperture meaning you're cut off from those venues of artistic control.
What we sorely need, for the next generation of phone cameras is for Apple (or whatever the manufactorer of the phone is) to expose APIs for developers to build apps which allow setting manual controls.
The reason they don't do that, however, is that Apple is really good at designing the experience of its users, and the people watching over the shoulder. You'll never get a blurry, or overexposed shot, they simply wouldn't allow it.
