A camera that takes photos with an invisible flash of infrared and ultraviolet light points to a smarter way to take photos in the dark.
Dilip Krishnan and Rob Fergus at New York University created the camera in an attempt to do away with intrusive regular flashes.
To make their "dark flash" camera, they modified a flashbulb to emit light over a wider range of frequencies and filter out visible light. The pair also had to remove the filters that usually prevent a camera's silicon image sensor detecting IR and UV rays.
Pretty phat. I'd like to see this come to the consumer market. For more on this check out this link:
