There are hundreds of smartphone photo apps out there, many of them designed to enhance the images we snap on our iPhones and Androids. But we think the best is Google's Snapseed. The simple interface belies the app's incredible power to edit and elevate any image. The thing that matters to us is what Snapseed does to food pics. With one swipe of a finger, we can saturate photographs with color, doing full justice to any dish. The app also allows us to easily adjust brightness so a restaurant entrée photographed in low light, whether it's a glistening ginger-glazed salmon or a juicy burger and fries, looks as if it were shot by a pro.
