iOS 8′s new Time-lapse video capture mode is a lot smarter than it sounds on first blush. Instead of taking individual images at predetermined intervals, it instead snaps photos at “dynamically selected intervals,” according to Apple's website.
But what exactly does this mean?
As discovered by Dan Provost of Studio Neat, this under appreciated iOS 8 feature doubles the speed of the Time-lapse and takes half as many pictures per second as the recording duration doubles.
This ensures that any Time-lapse you capture ends up being between 20 and 40 seconds long, “an ideal shareable length,” Provost writes. It's just one of the many ways the power of iOS 8 software makes you a better photographer.
