Taking pictures with an invisible flash

July 20, 2009

2 guys at the New York University created a camera that takes photos with an invisible flash of infrared and ultraviolet light.

The results have an odd colour balance that looks like a view through a night-vision scope.

So the camera takes a flash-free photograph of the same scene quickly after the dark flash image.

and software is used to combine the sharp detail from the first image with the natural colours from the second image

There are still some issues with materials that absorb UV or IR light, but I think it is a great first step and I can see this technology integrated in loads of different ways.
