Manual For iPhone

Manual is a high class, iOS, app for turning your powerful iPhone camera into a dSLR. Meaning, it takes all those automated focus and white level smartness and puts the control in your hands. Assuming you're comfortable with a manual camera, it seems like a nice option for doing it your own way.

Bonus, the intro video is quite amusing. Just the right amount of flippant absurdity. The outtakes aren't bad either.
