    Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. Is learning how to meter with your camera really necessary? With all the intelligent models out today, who needs it, right? Well, you may, depending on the type of killer photography you hope to produce. When it comes to the person behind the camera, there are a few types of photographers. First, there's the photog who just wants to snap away, not terribly concerned about how their photos turn out -- or, at the very least, not interested in knowing how to alter the camera. If this describes you, that's fine -- the latest-and-greatest compact cameras may be your cup of tea. But then there's the amateur shooter who desires a better understanding of how their cameras determine exposure, and if you fit into this category, this piece should be right up your alley.Metering is not a subject you can easily master, let alone explain entirely in an article of this length, but we can give you an idea of how it all works. I consistently see the faces of my workshop students glaze over as I wax rhapsodic about the wonders of metering, but I also notice wry smiles from time to time, which shows me the wheels are turning -- they begin to realize all the things they can do if only they can conquer this aspect of photography. However, comprehension and applied mastery are two separate balls of wax. Putting what you learn to practice is the start, and you can improve over a number of months, but true metering control in any situation requires years of practice.So for our 2012 pre-apocalyptic installment of Primed, we'll break down the world of camera metering, giving you a bit of history, dissecting the main components, describing what your camera wants to do and telling you what the future may hold. By the end, you'll have a better understanding of this vital photographic topic... either that or you'll be in a nice deep sleep.Note: Check out our recent Primed articles on aperture and image sensors to add to your metering knowledge.

  • Willard Boyle, man who revolutionized digital imaging, dies at 86

    We have some sad news to share with you today: Willard Boyle, the man who created the imaging technology behind everything from digital cameras to barcode scanners, has died at the age of 86. In 2009, Boyle shared a Nobel Prize in physics for inventing the CCD, which allowed people to capture images in digital format for the first time. It all began way back in 1969, when Boyle and his future co-Laureate, George E. Smith, started laying the groundwork for the CCD while working at Bell Laboratories. Building off of Einstein's photoelectric effect, the two eventually came up with a way to locate and quantify the electrons that are knocked out of orbit every time light strikes silicon. Boyle and Smith used this technology to create their own digital camera in 1970, as well as a TV camera in 1975. Prior to his groundbreaking invention, Boyle spent two years working for NASA's Apollo program and helped develop both the ruby laser and the semiconductor injection laser. The last three decades of Boyle's life were spent in Wallace, Canada, where he grew up and, on May 7th, passed away after battling kidney disease. He's survived by his wife, three children and an indelible legacy.
