So how do you make a Sundance movie for iPhone? You need four things. First, of course, the iPhone (Baker and his team used three). Second, an $8 app called Filmic Pro that allowed the filmmakers fine-grained control over the focus, aperture, and color temperature. Third, a Steadicam. “These phones, because they’re so light, and they’re so small, a human hand — no matter how stable you are — it will shake. And it won’t look good,” says Baker. “So you needed the Steadicam rig to stabilize it.”
The final ingredient was a set of anamorphic adapter lenses that attach to the iPhone.
