By using a flashbulb that emits ultraviolet and infrared light (neither of which the human eye can detect) instead of visible light, New York University's Dilip Krishnan and Rob Fergus have come up with dark photography that will neither blind your subject nor produce the unwanted glare of a harsh flash in the developed photo. On their own, IR and UV exposures produce photos that have strange, unrealistic coloring. But Krishnan and Fergus have taken care of that as well.

Recently introduced, the Canon G10 ($450) is the latest in its long-running series of "serious" point-and-shoots. At the heart of the camera is a tiny (about 40 square millimeters) image sensor similar to what you get in a pocket model....
