Sprint is ready to throttle its unlimited data plans, but only in 'congested' areas
It was a big promise: unlimited data, without quotes, throttling or restrictions. Sprint CEO Dan Hesse has repeatedly defended the company's pledge to offer a true unlimited plan, but now the company is quietly eating its words. Customers on Sprint, Virgin Mobile USA and Boost Mobile have all started receiving text messages warning them that heavy users will be subject to data "prioritization" next month in order to "provide more customers with a high quality data experience during heavy usage times." This prioritization (read: throttling) will only apply to the top 5 percent of data users and only in "congested areas," however, and Sprint tells FierceWireless that users will only experience limited speeds if they're connected to a congested cell site. A small concession to your unlimited data plan -- and one without a defined data cap -- but a small asterisk is still an asterisk.
Apple patents iOS 5's exposure metering based on face detection, keeps friends in full view
Many photographers will tell you that their least favorite shooting situation involves a portrait with the sun to the subject's back: there's a good chance the shot ends up an unintentional silhouette study unless the shooter meters just perfectly from that grinning face. Apple has just been granted a patent for the metering technique that takes all the guesswork out of those human-focused shots on an iOS 5 device like the iPhone 4S or new iPad. As it's designed, the invention finds faces in the scene and adjusts the camera exposure to keep them all well-lit, even if they're fidgety enough to move at the last second. Group shots are just as much of a breeze, with the software using head proximity and other factors to pick either a main face as the metering target (such as a person standing in front of a crowd) or an average if there's enough people posing for a close-up. You can explore the full details at the source. Camera-toting rivals, however, will have to explore alternative ideas.
Canon 'examining countermeasures' for 5D Mark IIIs experiencing top LCD light leak problem
Looks like the honeymoon period with Canon's beastly 5D Mark III is officially over. Over the past few weeks some users have noticed that light leaking from its top-mounted LCD can affect exposure readouts, and now the company has confirmed that it's indeed an issue. Essentially, the camera's meter can experience a shift in the readout whenever the LCD's backlight turns on in a dark situation -- ensuring frustration when composing shots. There's no word on how wide-spread the problem currently is, but Canon notes that it's "examining the countermeasures" and plans to circle back once it has a solution. Interestingly, PetaPixel also reports that some folks have experienced the phenomenon when ambient light beams down on the panel as well. This isn't the first time Canon's had an issue with a shooter after its release, but hopefully a fix will be in soon. You'll find more details at the links below, but while you're here, let us know if you've got a Mark III showcasing the symptoms in the comments.
Engadget Primed: Camera metering explained
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.
