More details emerge of the simple yet clever tech behind Live Photos →

I did not know this about the iPhone camera:

As you may already know, existing iPhones start taking photos the moment you open the app. This is how Apple provides the camera with the ability to take photos instantly, with none of the delay (‘shutter lag’) you see with some digital cameras. The camera has already taken and temporarily stored a whole bunch of photos, and it simply keeps the last one taken as you press the button and discards the rest …

Additionally, there’s good info on what the camera does for the new Live Photos.
