Five-minute short film from Apple, about people with severe hand tremors from Parkinson’s disease using the iPhone’s Action mode to shoot steady video — including filmmaker Brett Harvey, who was diagnosed at the way-too-young age of 37. There’s also a brief short with Harvey explaining the settings to shoot in Action mode by default, or to use voice controls to avoid needing to tap buttons.

Apple at its very best. If this doesn’t hit you, you’re not hooked up right.
