How a New Type of Filter Could Revolutionize Low Light Photography

Alex Cooke explains…

Low Light Issues…

Color photography is great. There’s a problem, though: the way we give color information to a camera sensor makes them really terrible at low light performance. A team from the University of Utah may have the solution.

Most modern digital cameras use a Bayer filter to selectively filter incoming light into red, green, and blue components, using their relative amounts to assign overall color values. While this is a good system for color photography, it’s not so great for low light photography.



Here’s the University of Utah’s bright idea for low light photography

University of Utah Electrical and Computer Engineering professor Rajesh Menon has developed a new camera color filter that lets in three times more light than conventional filters, resulting in much cleaner, more accurate pictures taken in lowlight. The new filter can be used for any kind of digital camera, but Menon is developing it specifically for smartphone cameras.
