There are hundreds perhaps thousands of photo and camera apps out there but most of the filters are already prepared for you. You just need to choose one to make a photo look as if it was taken by a professional photographer. That's the wonder of mobile photography. Point, shoot, and choose a filter for a pro-looking image you could probably submit to NatGeo. Up until today, there's not one app that allows you to make your own photo filter. But here comes the Shift, a new app that lets you create your own set of filters you can save for future use.
