You can usually tell when someone filmed themselves, and it's rarely the camera that gives it away. It's that they're the same size in every single shot. Same distance, same framing, video after video — because there's nobody standing there to change it.
I spent twenty five years being that person for other people. On the Queen's funeral I eased in very slightly on Kirsty Young's final piece to camera, and you'd probably never notice it, but it changed how the moment landed.
So this one is about getting that on your own, with a phone. Why I shoot in 4K and put out HD. How far you can push before it falls apart. The five shot sizes you actually need. What I use to see myself when there's nobody watching the frame.
