Smartphones and cameras are better than ever for night shooting, but there are still a lot of caveats. You have to hold your phone still to get decent photos as multiple exposures are added together, and video is out of the question. However, there's an emerging category of cameras dedicated to shooting in the dark using sensitive CMOS sensors and even infrared capability. Some of those models are designed for commercial or military purposes, like SPi Infrared's incredible X27 color night vision camera, but a few new models are aimed at consumers. One is the DuoVox Mate Pro, featuring a Sony STARVIS 2 CMOS surveillance camera sensor that's supposedly a thousand times more sensitive than the latest smartphone sensors.

Night vision is typically monotone--everything the wearer can see is colored in the same hue, which is mostly shades of green. But by using varying wavelengths of infrared light and a relatively simple AI algorithm, scientists from the University of California, Irvine have been able to bring back some color into these desaturated images. Their findings are published in the journal PLOS ONE this week. Light in the visible spectrum, similar to an FM radio, consists of many different frequencies. Both light and radio are part of the electromagnetic spectrum.
