It’s hard to beat Nokia when it comes to imaging from a mobile phone. Pioneering the phone camera since almost a decade, Nokia today announced their new Refocus app on the Lumia at Nokia World. The app lets you take a picture first and then chose where to focus on. It does that by taking a burst of shots and the software then works its magic. The app also lets you highlight a particular colour and grey out the rest of the image for some dramatic effects.
