Bored with your current photo filters? MacPhun just released 30 free ones if you’re a user of the Photos application for Mac. It’s called Filters for Photos; and it allows you to not only apply different filters but also lets you do it in selective amounts, fine tune them, selectively apply them in certain areas, etc.
Granted it’s not necessarily for the Lightroom crowd–though it would be amazing as either a Lightroom Plugin or on the iPhone. Either way, it’s fun just to experiment in your JPEGs if you’re bored this weekend.
