In keeping with their promises during the Lumia 1520 launch, the Nokia Refocus imaging app is now available to everything with a PureView camera. The next wave of smartphone cameras aren’t going to focus on the most megapixels. Software is what matters now, and Nokia has demonstrated that their camera tools are more than capable. The Nokia Refocus app enables Lytro-style refocusing by taking multiple photos at different focal points and stitching them together in software.
