Low light photography breakthrough on the way?

Lowlight

The boffins at Kodak have apparently come up with a ‘breakthrough’ method of improving low light photography. They have come up with a new light filter which they are hoping to supply to mobile phone camera companies and the rest of the imaging industry. Anything that makes low light photos better than they are now is a Great Thing in our book.

 When the shutter opens on a digital camera, an image is projected onto the sensor, which converts light into an electric charge. Most sensors use the Bayer mask: Half of the millions of cells on a checkerboard grid are filtered to collect green light and a quarter each are filtered to let through red and blue light. A computer chip then reconstructs a full color signal for each pixel in the final image. The new method, which has been under development for more than five years, adds “panchromatic” cells that are sensitive to all wavelengths of visible light and collect a larger amount of light striking the sensor. Tailoring software algorithms to this unique new pattern enables faster shutter speeds, which reduces blurring when capturing a moving subject…
