A crucial figure in the science of digital cameras died last month. Bryce Bayer invented the Bayer filter, the device that makes it possible for the monochromatic sensors in our digital cameras to render colors accurately. It’s quite a legacy, for sure. If you’re unfamiliar with how the Bayer filter works, take this opportunity to read about it via the Imaging Resource blog. It’s a fitting tribute to the man who made the device a reality, and it will make you a more informed photographer—just like the Bayer filter makes better digital photographs. Rest in peace, Mr. Bayer.
