This new ultra-compact camera is the size of a grain of salt and takes stunning photos

Ultra Compact Camera

The salt-grain-sized camera.

Scientific ingenuity means cameras keep on getting smaller and smaller, and the latest to appear is not only incredibly tiny – the same size as a grain of salt – it’s also able to produce images of much better quality than a lot of other ultra-compact cameras.

Using a technology known as a metasurface, which is covered with 1.6 million cylindrical posts, the camera is able to capture full-color photos that are as good as images snapped by conventional lenses some half a million times bigger than this particular camera.
