Amazon brings HDR video streaming to the UK
Sure, Amazon is focusing on Ultra HD (4K) broadcasts for its upcoming streaming content, but that isn't all that the company has on the agenda. Two months after it began supporting high dynamic range (HDR) in the US, Prime members in the UK now have the chance to watch some Amazon Instant Video shows in more vivid detail.
Dolby is launching its super-vivid IMAX theater competitor in the Netherlands
Dolby has just announced a huge new project, but it's not about audio as you'd expect -- it's about the upcoming launch of its IMAX competitor called Dolby Cinema. This giant screen format will be able to project movies using the "Dolby Vision" technology (something it's been working on for years), which combines high dynamic range videos with something else that the company's keeping a secret. High dynamic range or HDR videos, as you might know, can show shadows and light as you'd see them in real life (take this Disney Research video, for example). Dolby goes as far as to claim that its technology's "contrast ratio far exceeds that of any other image technology on the market today."
Disney Research uses trippy camerawork to tell a tale of immortality
Disney Research has done an awful lot of neat stuff in the past, but it hasn't really approached Walt's bread and butter before: video. Instead of going with animation, though, the team is using some pretty slick camera tricks to tell a live-action story about unconditional love and a mother attaining immortality through her son. Yeah, we thought the premise was kinda weird too. Dubbed Lucid Dreams of Gabriel, it features techniques like novel computational shutters, high dynamic range tone-mapping and a scene with a few different frame-rates happening all within the same shot. By applying these effects in post, the filmmakers, with help from ETH Zurich, were able to achieve results that otherwise couldn't be produced with conventional camera equipment. Fitting, considering the title references conscious dreams, eh? The full version of the short is due sometime in August, but you can watch the teaser for yourself just after the break.
Google+ photos get more 'pop' with new dynamic range tool
So far, you've had to use Snapseed on your phone to add high dynamic range effects to Google+ photos after you've taken them -- not very convenient if you're at your computer. That won't be a problem after today, though. Google has brought its mobile apps' HDR Scape tool to the web-based photo editor in Google+, letting you brighten shadows and tone down highlights in a single step. And if you're fussy about your edits, it's now easy to zoom in and verify that everything is just right. The new tools are already available for some Google+ users, and they should reach the rest of the social network in the near future.
Rambus Binary Pixel brings single-shot HDR photos to phone cameras
Most high dynamic range photography 'cheats' by merging multiple exposures into a composite image, which can lead to blurry shots. While HDR camera technology is catching up and will even let us record HDR video on our smartphones, Rambus believes its new Binary Pixel technology can achieve the effect with less waste. Its new imaging chip tries to replicate the human eye's range through setting light thresholds and oversampling the scene in both space and time. The results are more natural shadows and highlights down to the pixel level, with processing processing fast enough for video. The overall image reportedly suffers from less noise as well. Companies will have to talk to Rambus to implement Binary Pixel, although it's a considered a drop-in technology that should talk to existing processors and camera sensors, whether it's for smartphones or point-and-shoot cameras. Rambus may just want to hurry if it hopes to get noticed -- it's joining an increasingly crowded field.
Sony's stacked Exmor RS phone camera sensors detuned over quality worries
Sony would still like you to get excited about its upcoming Exmor RS stacked CMOS image sensors -- just not too excited. Both the 8-megapixel IMX134 and 13-megapixel IMX135 are scaling back from their original RGBW (red, green, blue, white) coding to an ordinary RGB over concerns that they aren't meeting Sony's "image quality standards" as originally designed. Consequently, either sensor will be less sensitive to light and diminish some of that high dynamic range magic. The company also doesn't want to get our hopes up for a quick arrival on shelves and clarifies that there's a phased launch starting in January. Mobile shutterbugs may be crestfallen knowing that Sony won't have the best possible camera sensor in future Xperia phones, but the honesty at least guarantees that the company gets a timely return on its $994 million investment.
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.
AMP camera records 1080p HDR video, you probably can't have one
We've already seen cameras that let you pretend you live in a radioactive apocalypse shoot HDR video, combining overexposed and underexposed images into one surreal composite. But so far, that kind of dystopian trippiness has been relegated to experiments and rigs using two lenses. But here we have AMP, a portable-enough five-pound camera that splits the light into three sensors, giving it a range of 17.5 stops to "reveal reality" in our drab, incomplete lives. The single-lens camera shoots 1080p video at 24fps or 30fps, records raw, uncompressed data to an SSD, and works with Nikon F-Mount-compatible lenses. To give you some perspective on the amount of sheer storage required, AMP promises a 256GB SSD can hold 30-plus minutes of footage, with 24fps video consuming less space than the 30 fps variety. It'll be available later this summer for some unknown sum, but not as a mass-produced product. Rather, it'll end up in the hands of a select few prosumers who add themselves to a waiting list. Assuming you won't be one of the chosen, you can get your fill of reality in a pair of demo videos after the break.
Sony licenses Dolby's HDR tech to make brighter, better Bravia HDTVs in the future
Ever since BrightSide first showed off its Extreme Dynamic Range displays that claim to display luminance throughout the entire range of vision back in 2005, we've been waiting for the technology to overtake current LCDs. The years have passed and a after being purchased by Dolby all we've had to show for it so far is a slightly smaller bezel and a handful of reference displays for professionals from Sim2. That could turn around though, now that Dolby has licensed the technology to Sony to make BRAVIA LCD HDTVs with. Of course, so far Sony hasn't done much with its implementation of OLED and after six years we're cautious to get too excited before actual products are announced, but we could be in for some much better looking displays very soon. Check the press release after the break for details or slick the link to Sim2 below for more explanation on just what this technology is and why you should look forward to it.
Nikon D5100 impressions, head-to-head with D7000
Nikon has stirred up the camera crowds once again with its newly released D5100, filling the industry with the buzz of a new high-resolution articulating screen. In terms of consumer DSLR options, the D5100 has taken on the role of the mid-range model in Nikon's product line between the D3100 and the D7000 and we think it assumes the part rather nicely. In terms of price, the D5100 fits right in as well, fetching an MSRP of $900 (vs. $700 and $1600, respectively for the two aforementioned camera kits). Of course, the D7000 lands you the better 18-105 f/3.5-5.6G ED AF-S VR lens, a larger and brighter viewfinder, built-in focus motor, weather-proof sealing, and a few other internal upgrades. But don't judge too quickly, because we've had some time to play with Nikon's latest creation and the D5100 can certainly shoot along with the big boys of consumer cameras -- read on past the break for our impressions and comparisons with the D7000. %Gallery-121549%
HDR photo hands-on with iPhone 4 and iOS 4.1
I've never used one of the HDR apps, so I was eager to try out this new feature using iOS 4.1 on my iPhone 4. Launching the camera now gives you an HDR option at the top of your screen. It's automatically set to off. When you toggle the option on, it will automatically switch the camera flash to off. Using HDR will provide you with two shots -- one normal shot and one with HDR utilized. For my test subjects I used: A shot of a window from a few feet away. A shot of a window standing at the window. A dark shot using the cat lounging next to the iMac as a model A well-lit shot using one of the other cats, who happened to claim a kitchen cabinet as his own, as a model. The most noticeable difference came from the window shot taken a few feet away. As seen above, the normal shot has the outside areas overexposed while you can clearly see the apartment building across from mine -- including some detailed areas -- in the HDR shot. This shot was taken about eight feet from the window.
Canon patent application takes in-camera HDR to the pixel level
There's certainly cameras out there that offer in-camera HDR (or High Dynamic Range), but none that go quite as far as what Canon has detailed in a recently published patent application. The short of it is that Canon's proposed method would alter exposure values at the individual pixel level, which should effectively emulate what's now possible but stitching together multiple photographs taken at different exposure settings -- and, for that matter, even open up some new possibilities since those single-pixel exposure values could be tweaked at will. Of course, there's no indication as to what type of camera the method would be used in, or any evidence that Canon has actually taken it beyond the patent application stage, so we wouldn't recommend getting too excited about the possibilities just yet.
Ben-Q debuts E1260 HDR digicam with 12-megapixels, 720p video
Ben-Q might not be the most well-known name in the gadget game, but it does have a pretty solid track record when it comes to entry-level consumer electronics. The company's newest shooter might not come in the most eye-pleasing package, but the 12-megapixel E1260 HDR should do well enough in capturing those spontaneously heartwarming (or cloying) scenes with the family this summer: 720p video! 28mm 4x optical wide angle zoom lens! A 'passable' 2.7-inch LCD display! And how about that HDR image enhancement technology? Apparently, this bad boy's "high dynamic range" feature manages high contrast lighting to eliminate excessive backlight. Intrigued? This one should hit store shelves sometime next month. PR after the break.
Ricoh CX2 has 10.7x optical zoom, CX1 pedigree
Ah, the cruelty of rapid refresh cycles. It was only six months ago that the well reviewed CX1 hit the scene, but already Ricoh is trotting out its replacement in the form of the CX2. You needn't fret though, as the new shooter retains its predecessor's winning features while adding a few goodies of its own. The zoom has gone from 7.1x to 10.7x, taking it comfortably into the superzoom category, continuous shooting gets upgraded from 4 to 5 fps, and face detection and AF have been enhanced. The latter features should make the new cam easier to use for novices, but when you add up the whole package -- including the already competent 9 megapixel CMOS sensor and HDR imaging capabilities inherited from the CX1 -- you have to wonder if this camera isn't too good for the point and shoot moniker. Suggested UK price is £299.99 ($495), and it should be available in early September. [Via Akihabara News]
HDR imaging for the cheap and gifted
People who are seriously after HDR output tend to pony up the dough for a big and chunky DSLR, knowing they'll get the highest quality possible. But if you're short on cash, here's a homebrewed mod that combines a gutted Polaroid x530 Foveon shooter with a Viliv to produce HDR-like imagery on the cheap. Essentially, the Viliv does all the processing and control work, while the el cheapo camera is used for its ability to save to raw format. You could instead pick up a compact Ricoh CX1 and save yourself a lot of trouble, but where's the fun and tinkering in that? The homemade hardware might not be pretty to look at, but make your way past the break to see if the results are worth the effort.[Via Hack a Day]
Ricoh's CX1 camera gets reviewed
The kids at Photography Blog have finally got their hands on that Ricoh CX1 that won our respect not too long ago, and they've been cool enough to post a review online. The camera, the reviewer said, begins where the ol' R10 left off, throwing features like multi-pattern auto white balance, multi-target auto focus, and 4fps continuous shooting speed into the mix, making this "the best Ricoh point-and-shoot yet." That said, it can't all be groovy -- the review goes on to cite the camera's "bog-standard" 640 x 480 / 30fps video and rudimentary face detection as "nothing to write home about." Image quality -- often a deal-breaker for this company -- has greatly improved, with a new 9 megapixel CMOS sensor sporting "a now usable ISO range of 80-800." Of course, the big news is the camera's high dynamic range. DR mode is, for the most part, "radical and very effective." But there's much more to it -- hit that read link for all the gory details.
Ricoh's CX1 point and shoot combines two shots for greater dynamic range, glory
While high dynamic range is only recently getting some attention in the gaming and display worlds, for decades it's been a tool of serious photographers wanting eye-popping exposures. Now Ricoh's gone and offered it to the masses with its latest consumer digi cam, the CX1, creating a "dynamic range double shot" mode that takes two images nearly simultaneously with different exposures, then combines them automatically to present the best bits of both. It features a 9 megapixel CMOS sensor fronted by a 7.1x (28-200mm) lens and backed by a 3-inch LCD. VGA videos are a bit disappointing these days, but 120 frames per second can be captured at that resolution, which is good news for slow-mo junkies. UK release is mid-March for £299, about $430, and we expect/hope it'll be lighting up dim photos Stateside around the same time. %Gallery-45312%[Via PhotographyBLOG]
SIM2 Solar Series infinite contrast HDR LCD ships in Q2
After several years high dynamic range LCD technology is finally ready for market, now that SIM2 and Dolby are showing off this Solar Series 47-inch screen at the 2009 Integrated Systems Europe show. Just like last year's prototype, it's both brighter (4,000 cd/m2) and has a greater contrast ratio than any flat panel currently available. The 2,206 LEDs can provide up to an infinite contrast ratio and supposedly match real world visuals thanks to 16 bit color processing. The only bad news is that even with a name change to Dolby Vision, that ugly wide bezel from the BrightSide days still remains. We'll have to wait until closer to the Q2 shipping date to find out the price, but with SIM2's high end reputation it won't be cheap.Update: SIM2 pinged us to say that only the professional version will be available in Q2. The "consumer unit" won't be formally launched in the US until CEDIA this September. Gallery: SIM2 / Dolby Vision Solar Series HDR display
Dolby announces Vision release for Q1, Volume release for now
We can't say that we've ever been utterly stoked for Dolby Volume, but we suppose it's a nice extra in TV sets and set-top-boxes so long as the cost of inclusion is negligible to the consumer. That said, Dolby's making darn sure the crowd at CES knows that it's infiltrating sets in the US and Europe as we speak, and it'll be showcasing a number of Toshiba REGZA LCDs in particular. In related news, Dolby Vision -- part of its High Dynamic Range series -- will be showcased in a SIM2 prototype LCD here in Vegas. Better still, Dolby is currently working with SIM2 in order to develop an HDR-enabled LCD display, and while we highly doubt this is the set that's coming in Q1, we are told that the technology will be available in some form or fashion this quarter. Patience, friends -- it's the only choice.
SIM2, Dolby showcase 46-inch HDR display prototype
Well, would you take a look at that. Right on cue, Dolby and SIM2 are collaboratively showcasing a 46-inch 1080p display built around the former firm's high dynamic range technology. The HDR-enabled LCD HDTV boasts 1,836 LED-based backlight units (designed / developed by SIM2), a full 1,920 x 1,080 resolution, brightness level greater than 4,000 cd/m2, an "infinite" contrast ratio, 16-bits of luminance and a Xilinx Virtex field programmable gate arrays (FPGAs) chipset. Additionally, the prototype employs a design created by Giorgio Revoldini, and while we can't imagine hearing of a release date anytime soon, the two firms aren't wasting any time putting the new set on a world tour to presumably wow onlookers. Hey SED, you taking notes here?
