You'd be forgiven for thinking that Nokia's "shoot now, focus later" photography app, Refocus, required PureView hardware to run, because until now it's only been available on PureView-branded phones. As it turns out though, the app has just been made compatible with all Lumia phones running Windows Phone 8, including ones with down-to-earth camera modules. It works by means of a "focus sweep" -- you hold your phone steady for a couple of seconds while the camera scans the scene ahead at a range of different focal lengths and then combines these into a single dynamic image (like the one below) that lets anyone adjust the focus and background/foreground blur later, after the file has been saved and shared. If you're reading this on a Lumia, the source link below should take you where you need to go.
