Yahoo has released a feature that lets people post Flickr photos to their Twitter accounts.

The Twitter2Flickr feature requires that you enable Flickr as an approved application that can tweet under your username.

Then, when you click the "blog this" link above a photo at Flickr, you're presented with the option to twitter it. The tweet will come with a "flic.kr" shortened URL.

Flickr has a large number of users, and its use is amplified by the fact that other sites can make use of Flickr data through an API (application programming interface). The Twitter integration is a modest example of Yahoo's attempt to make its sites less of a walled garden by working better with other Web properties.

A Twitter search for Flickr photographs indicates that a lot of people are making use of the integration, which had been in beta testing since earlier in June.

The Olympus E-P1 camera, a hybrid designed to combine advantages of both compact cameras and SLRs, is a welcome arrival in a digital camera market struggling to find new directions.

The small and light camera that debuted Tuesday features interchangeable lenses and relatively large sensor that endow SLRs with flexibility and higher image quality, but it's also got a small body of a compact camera. It has the potential to appeal to SLR owners who want something smaller and to compact camera owners who want something better, if Olympus can convince people to surmount a significant obstacle, price.

Like most hybrids--gaming laptops, for example, or bicycles with aspects of both road bikes and mountain bikes--the E-P1 sacrifices specialization for versatility. But the digital camera market is saturated, and the E-P1 is a promising member of a newer camera breed.

There are a handful of competitors with similar aspirations. Canon's G10, the newest in its G series of high-end compact cameras, is one example. Nikon's GPS-enabled P6000 is another, though, like the G10, it doesn't have an interchangeable lens. And Panasonic's G1 and GH1, which employ the same Micro Four Thirds lens and sensor standard as the E-P1, are probably closest.

The biggest knock against these cameras is price. Their relatively large sensors--especially those in the Micro Four Thirds cameras--cost a lot to manufacture, and fast electronics and high complexity just make things worse. Few people are willing to spend more than $300 on a camera, much less the hybrid cameras.

A new tremor on Thursday traversed a photography world already shaken up by the arrival of digital technology as Phase One, a Copenhagen-based company that caters to professional photographers, announced a plan to acquire some high-end photography assets from Eastman Kodak.

To nobody's surprise, Kodak wound down its 35mm Kodachrome film product on Monday. In the rarefied realm of medium-format photography, where film sizes are much larger, and the demand for quality is much higher, the change to the digital era has been equally jarring.

Phase One, though, was digital from the outset, and it's become a force for consolidation in the digital medium-format photography market. The company announced its plan to acquire technology and hire employees from Kodak's Leaf medium-format brand just months after taking control of Japanese medium-format camera maker Mamiya.

Leaf sells medium-format cameras, digital-sensor camera backs, and Leaf Capture photography software. The latter two products, but not necessarily the first, will live on under Phase One management.

The vast majority of cameras sold today are either all-in-one compact models or higher-end single-lens reflex (SLR) cameras with interchangeable lenses and larger, better image sensor chips. Medium-format cameras are another step up the ladder, costing tens of thousands of dollars for digital models, employing even larger sensors with more megapixels, catering to professionals almost exclusively, and offering not just interchangeable lenses but also sometimes interchangeable viewfinders and "backs," too, where image sensors or film packs are mounted.

Once the Leaf deal closes in about two weeks, Phase One Chief Executive Henrik O. Hakonsson said in an interview, Phase One will continue to develop and sell Leaf's digital backs and photography software through a new Israel-based company, Leaf Imaging. The new company will sell products that use Phase One's image sensor chip technology but that maintain Leaf's user interface approach, he said.

"We do not believe you can box everything together and serve all the pro photographers' needs," Hakonsson said. "One main thing we can get from Leaf is the ability to serve this market through a broader range of solutions than our own current design and engineering is able to offer. Another is, we need to be able to have more critical mass" in designing and manufacturing high-end image sensors.

Terms of the deal weren't disclosed.

The changes illustrate just how complicated the digital transformation is for the high-end photography market, populated by the likes of high-priced photographers who shoot Vogue fashion ads and close-ups of jewelry and watches.

Back in the film era, it wasn't much more expensive to produce larger frames of film for these more demanding photographers than the 35mm film size used by mainstream folks. But in the digital era, with the constraints of processor manufacturing, it's vastly more expensive to produce larger image sensors than small ones. Phase One's top-end camera, the 60-megapixel P65+, costs about $40,000.

That economic reality is behind much of the medium-format market turmoil. Phase One, though, has grown each of the last seven years. "I don't think there's a simple recipe. I think it's equal parts hard work, good thinking, and a little bit of luck," Hakonsson said.

Phase One faces plenty of challenges, though--notably Canon's 21-megapixel, $7,000 1Ds Mark III and Nikon's newer $8,000 D3X. These models benefit from those companies' deep engineering, manufacturing, and marketing experience and from their broad customer bases. Both those companies are aiming their cameras at studio photographers with medium-format expertise.

Will Leaf's camera survive?
Leaf offers both Aptus-branded digital backs and AFi-branded digital cameras. While Phase One has rights to sell both those lines, it has committed so far only to sell the digital backs, Hakonsson said.

That means that Phase One's move will likely reassure Leaf digital-back customers, but those using the AFi camera still face an uncertain future. The Leaf AFi was developed in partnership with two other medium-format brands, Franke and Heidecke's Rollei and Jenoptik's Sinar, which sell their own versions of the camera, but Phase One declined to join that partnership earlier.

That camera partnership's future already is under a dark cloud. Franke and Heidecke, which manufactures the camera system for the trio, filed for bankruptcy protection earlier this year.

Phase One will conduct a "thorough investigation of the product concept," Hakonsson said, "but there is no guarantee that Leaf or Phase One will support the system. We do have product rights to it and are able to do it, but it has to come down to a business decision whether it makes sense to revive the system."

The allies behind the system have made some progress since its inception, but Phase One remains concerned about issues with optics, durability, and service, Hakonsson said.

Digital-back business
Digital backs, on the other hand, are a better business for the company. They can be used with a range of medium-format cameras and with other more exotic models, such as large-format cameras and view cameras--the kind with the collapsing bellows most people associate with 19th-century photography but that still are in use.

In this segment of the market, where photographers are more set in their ways, older camera designs can last a long time. Just selling backs means the image sensor component of the camera can be changed relatively often to keep up with technology, but the rest of the system, which changes more slowly, can be used for longer.

"Six years ago, Contax discontinued production, but we've never sold as many Contax digital backs as we do today," Hakonsson said.

The other major power in the medium-format realm is Hasselblad, whose recent designs such as the H3D-II have favored integrated camera designs rather than interchangeable backs. That integration move deprived Phase One of a lot of potential digital back business and provided motivation for the Mamiya and Leaf deals.

Phase One has about 100 employees of its own and another 150 through Mamiya. The Leaf group is in the process of hiring about 25 employees who lost their Kodak jobs, he said.

Phase One has primarily used Kodak's image sensors, but its more recent models, including the high-scoring P65+, are built by Canadian manufacturer Dalsa. "For maybe the last 18 months, Dalsa has been ahead," he said.

The camera in Apple's upcoming iPhone 3G S sports not just video, but also some new features besides the usual not-so-useful bump in megapixels.

The phone, available next week in the United States and some other countries, comes with a 3-megapixel camera compared to the current iPhone 3G's 2 megapixels. It can shoot video at 30 frames per second at VGA (640x480) resolution, matching competing phones and addressing a shortcoming of the current phones.

Videos can be edited on the iPhone 3G S by trimming the sequence of still images taken from the video.

But the iPhone 3G S can do more than just shoot video, said Phil Schiller, Apple's senior vice president of worldwide marketing, at the company's Apple Worldwide Developer Conference here. People can share videos through e-mail, MMS, Apple's MobileMe service, and YouTube.

And taking advantage of the iPhone's relatively powerful hardware, people can "scrub" through a video--that is, click and drag to fast-forward and rewind--as they watch to jump to the spot they want. Likewise, they can trim videos to pare back to the desired portion. The scrubbing and trimming uses an interface that displays the video as a filmstrip sequence of still frames.

The iPhone 3G S also includes still camera upgrades for the photography crowd--and it should be noted that the iPhone rivals SLRs for activity on Yahoo's Flickr photo-sharing site, outpacing all mobile phones and all but one actual camera.

First is autofocus. Mobile phones' tiny image sensors often mean everything is in focus whether you want it to be or not, but the iPhone 3G S will let come with autofocus to try to ensure that the right part of the image is sharp. A feature called "tap to focus" lets people tap on the screen image to focus the camera on a particular part of the image--foreground or background, for example.

Coming along with autofocus is an automacro mode, too, for close-up shots, Schiller said.

Apple also said the new phone has better low-light performance--a common bugaboo not merely for mobile phone cameras but for regular point-and-shoot models as well.

The iPhone 3G S will cost $199 for a 16GB model and $299 for a 32GB model, Apple said. Other features include better battery life and faster performance.

Canon's Rebel T1i

Apple released a software update Thursday to let its Aperture 2, iPhoto '08, and iPhoto '09 photo-editing software handle raw images from three newer SLRs, Canon's Rebel T1i, Nikon's D5000, and Olympus' E-30.

Higher-end cameras offer raw image formats that provide more flexibility and quality than JPEG, but the raw file formats are proprietary, vary from one camera model to another, and require companies such as Apple and Adobe Systems to release a constant stream of updates. Microsoft relies on camera manufacturers to supply software for Windows that can interpret the raw data, which is taken directly from camera image sensors without in-camera processing.

Camera makers typically supply their own software for handling raw images, but many people prefer their own photo software.

Further detail on Apple's support is available on Apple's raw camera support page.

Half a year after the camera's debut, Canon released promised firmware that updates its vaunted EOS 5D Mark II SLR with the ability to manually control camera settings while shooting video.

The much-desired feature lets users set aperture, ISO sensitivity, and shutter speed manually. It was the first Canon SLR to support video, and the only one so far that can shoot 1080p video at 30 frames per second, but previously it only could shoot video in a fully automatic mode.

The firmware 1.1.0 update is available from Canon's Web site, as are update instructions (PDF).

The omission led to much carping among those who expected more control over their imagery from a 21.1-megapixel SLR that costs $2,700 with no lenses. For example, people couldn't specifically set a wide aperture to attain a shallow depth of field that blurs the background behind the video subject, a cinematographic effect that's hard to attain with standard point-and-shoot video.

The new video mode is activated using the standard controls for setting ISO, aperture, and shutter speed after the camera dial is set to the "M" mode for manual shooting. See the excerpt from the user manual update below for details.

On my camera, the update took about two minutes to install and my testing showed that the feature worked as advertised. The firmware fixes five other glitches, too; the full list is at the bottom of this post.

Update 8:30 a.m. PDT: Contrary what I found earlier, aperture and shutter speed can be changed while you're shooting. Of course doing so shakes the camera and adds audible noise if you're using the built-in microphone, and exposure changes in fixed steps, not smooth transitions, that are pretty glaring in the video.

You also can set ISO to "auto," in which case the camera makes its best guess about exposure while leaving shutter speed and aperture alone.

Aside from the video feature, here's what Canon says firmware 1.1.0 fixes:

• Disables the function of the depth-of-field preview button when images are played back or when the menu screen is displayed on the LCD panel.

• Fixes a phenomenon where the peripheral illumination of images cannot be properly corrected, even if the images were captured with the lens peripheral illumination correction function set to Enable. Digital Photo Professional software version 3.6.1 or later (for Windows and Macintosh) can be used to automatically correct the peripheral illumination of raw and JPEG images that were captured in the Peripheral Illumination Correction setting with cameras that have Firmware Version 1.0.7 or earlier.

• Fixes the algorithms of the Auto Lighting Optimizer function when Custom Function C.Fn II-3 Highlight tone priority is enabled.

• Fixes incorrect indications on the Arabic, Romanian, Spanish, and Ukrainian menu screens.

• Changes the battery information displayed on the camera when using the optional Battery Grip BG-E6.

Updated 7:16 a.m. PDT with further details from Canon in Europe, and 9:20 a.m. with further details from Canon USA.

Canon plans to release firmware June 2 to address a common complaint about its EOS 5D Mark II, a $2,700 digital SLR that's generally been lauded for its image quality but criticized for its lack of manual controls when shooting video, the company said.

SLR cameras give photographers close control over settings including shutter speed, aperture, and ISO sensitivity, and the enthusiasts and professionals who buy high-end cameras often understand and use those options. Since the 21-megapixel 5D Mark II was introduced a half year ago as Canon's first SLR to feature video abilities, the video operated in a fully automatic mode in which the camera selected those settings.

Manual control over video will arrive with Canon's 5D Mark II through a June firmware update.

That became a common cause for complaint. For example, people couldn't select a wide aperture, or F-stop, to ensure a shallow depth of field that would direct attention to a video's subject while making the background an undistracting blur. The lack of manual controls contrasted with two big video advantages of the 5D Mark II, the ability to shoot 1080p video at 30 frames per second, and a large, full-frame sensor that's particularly good at dealing with difficult low-light conditions.

"This new firmware will accommodate a great number of user requests for manual exposure control in the EOS 5D Mark II video mode. Manual exposure control while shooting video on the EOS 5D Mark II is expected to make a big impact with cinematographers and videographers using the 5D Mark II for high-end HD video production," Canon said.

A customer newsletter said the feature will permit control over ISO, aperture, and shutter speed. Canon's European press release was more forthcoming, saying that shutter speed would range from 1/30th of a second to 1/4000th and that ISO would include the camera's regular span of 100 to 6400 and also the extended H1 setting of 12,800.

Medium-format digital cameras, which have larger sensors and higher price tags than even high-end SLRs, didn't fare so well in earlier tests of sensor quality by measurement firm DxO Labs, but Phase One's newly tested top-end technology has risen to the top of the DxOMark Sensor test.

Phase One's 60-megapixel P65+ camera scored 89.1 on the test, edging out the Nikon D3X, which scored 88, according to data released Thursday. In addition, the 51.7-megapixel Hasselblad H3DII 50, an older model than Phase One's, scored 78.2. Click here to compare the two models and Nikon's D3X.

The DxOMark sensor test measures a camera sensor's dynamic range, color depth, and low-light performance. DxO Labs cautions that differences of less than 5 points aren't really distinguishable, and of course many other factors including price, lens quality, autofocus, and resolution factor into overall camera quality.

The P65+ features the best color performance yet, but DxO Labs said its comparatively good performance in low-light conditions helped it carry the day.

Carl Zeiss' camera lens division renewed a partnership with Sony for another five years, the companies announced Wednesday.

The partnership began in 1996 with a Sony camcorder using a Zeiss lens, then extended to compact cameras. More recently, with Sony's entry into the SLR market, Zeiss-branded lenses are available on those high-end cameras, too.

Another electronics giant making its way into the camera market, Panasonic, has adopted a similar strategy with another German camera company renowned for its engineering, Leica.
