One of my favorite photo editing applications for both iOS and OS X recently received major upgrades. Today, Polarr 2.0 for Mac is available and ready to download. With a new interface, adjustments to filters, and extension support for Photos, it is one of my most recommended applications.
My review of Polarr 1.0 shared some of its power but new powerful and easy to use features are hear. Check it out on the App Store for Mac (and iOS).
