I love my iPhone 6+, and have been shooting, editing, and publishing lots of glorious video with it, on the road.
I really enjoyed seeing Tristan Pope's behind-the-scenes exploration of how "Romance in NYC" came to be. "The iPhone has limitations," he says "but the limitations themselves spur creativity." Couldn't agree more.
About the tools:
Tristan used MoviePro app for iOS which offers fine grain control for ISO, exposure, temperature, and uncompressed audio as well as support for Bluetooth microphones. Tristan even worked directly with the developer who incorporated his feedback into the app. Tristan also used Glidecam, as while iPhone 6 has cinematic video stabilization, he found this excellent for moving shots that still need natural camera motion, Joby Gorrilapod and Redicam mount.
