Snapshots by quantum dots: Look out, CMOS image sensors. There's a new kid in camera-town

In the early 2000s, the commercialization of CMOS image sensors led to smaller and smaller - and cheaper and cheaper - digital cameras. Now the thinnest of mobile phones contains at least two camera modules, and all except the most dedicated photographers have stopped carrying a separate camera, concluding that the camera sensors in their phones take pictures that are good enough.
