This experimental camera can focus on everything at once
A camera lens, historically, can only focus on one thing at a time, just like the human eye. That could be a thing of the past, though, thanks to a breakthrough lens technology developed by researchers at Carnegie Mellon University (CMU) that can bring every part of a scene into sharp focus, capturing finer details across the entire image, no matter the distance.
Traditional lenses are limited to sharpening one focal plane (the distance between an object and your camera) at a time, blurring everything behind or in front of that object. That effect can bring a sense of depth to images, but seeing a full picture clearly typically requires you …
