Nokia's Living Images is a new feature coming to Windows Phone 8.1 and their Lumia Cyan firmware update for the high-end PureView devices, like the Lumia 1020, Lumia 1520, Icon and so forth. Living Images captures a few seconds before you snap a photo, so that when you're browsing through your Camera Roll or StoryTeller, your photos come alive. It's like Cinemagraph, but without having to think, as it just works automatically.
A Nokia Camera Beta update a few weeks ago introduced Living Images, but no one could use it without the Cyan firmware. Even those with a Lumia 630 can't use it as that device is not PureView. But I started getting tips from people who had Living Images enabled, though they didn't know how it happened. Finally, Jason in our comments explained a simple trick to get it working, at least mostly.
