Dark camera flash with infrared / UV light could revolutionize low light photography

This is some really phenomenal core technology that could finally solve the classic problem of blurry low light photos. The leftmost photo is a photo taken with a dark flash, and the 2nd photo is one taken using ambient light at high ISO (noisy!). The 3rd photo is the synthesized version that actually looks even better than the 4th reference photo taken with a long exposure.

As a photographer, one of the hardest tradeoffs has always been ISO (fast shutter but noisy, vs slow shutter but blurry) and whether to use flash (annoying, noticeable, vs. having enough light). But this sounds like best of all worlds.

At the very least, tech-savvy paparazzi will now be able to take low light photos undetected.
