"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. The lenses were prototypes from Moondog Labs, and Baker said they were essential to making Tangerine look like it belonged on a big screen. 'To tell you the truth, I wouldn’t have even made the movie without it,' Baker says. 'It truly elevated it to a cinematic level.'
"Like any conventional film,Tangerine underwent post-production. 'With a lot of these social realist films, the first thing you do is drain the color,' Baker says."
