The best camera you have is the camera you have on you, and more often than not that's probably your phone. A new machine learning system from MIT wants to help make those phone pictures easier to take and better looking, which sounds good to us. It does this by retouching any photo automatically with, it reckons, the accuracy of a professional photographer – and it can run on a smartphone in real time, showing you what the best version of your picture would look like before you even take it. "This technology has the potential to be very useful for real-time image enhancement on mobile platforms," says Jon Barron, a research scientist at Google who worked on the paper describing the system. "Using machine learning for computational photography is an exciting prospect but is limited by the severe computational and power constraints of mobile phones," he says.
