iPhone in the Woo (2)

Just hooked a power inverter up to the cigarette lighter and mounted it behind the dash, plugged the iPhone dock into the power inverter using the included dock/power brick, and went line out on the dock to line in on the stereo. Instant iPhone integration!
Whole setup cost 0, not including the phone (it’d be 0 less if you already owned a headunit with line in). It charges the iPhone while playing music through the stereo (digitally), as well as rings through the stereo in the event of a call.
Upper Crust: iPhone

Better color in the iPhone shot. But it might have done too good a job with the white balance: ideally, it would have left in a little bit of the warmth of the lighting.
This is a scene where there’s probably no "right" answer to the exposure. The Nexus preserved the highlights in the far ceiling, at the cost of shadow detail. The iPhone did the opposite.
Personally, I think the iPhone shot is more pleasing but it’s a tough call.
