    • Sony Unveils HDC-4300 World’s First 4K System Camera with Three 4K Image Sensors

      Press release from #NABShow by blog.Sony.com Las Vegas, April 12, 2015 – Sony’s next generation of HDC series camera technology provides the ability to use the high magnification wide zoom range lenses currently employed by HD 2/3-inch systems while maintaining an adequate depth of field to properly show all of the action in live event broadcasting. The new HDC-4300 is the world’s first camera to use three 2/3-inch 4K image sensors¹. It supports the same B4-mount lenses as well as the same control surfaces as Sony’s industry leading HDC-2000 series cameras. The existing HDLA-1500 series, control and shading systems, viewfinders and master set-up units are all interchangeable between the HD and 4K systems. Directors and operators can keep their approach to live events — including camera angles, zoom ranges and iris settings – while using familiar camera technology. “This camera provides 4K capabilities and a workflow that content producers are instantly familiar and comfortable with,” said Rob Willox, marketing manager for content creation systems, Sony’s Professional Solutions Americas. “We’ve developed an approach that allows the large existing HDC series user base to employ 4K advantages such as 8x high frame rate and 4K cut-out and zoom while using a familiar infrastructure and signal path.” The new HDC-4300 is capable of 4K/HD operation, with 2x, 3x Super Slow Motion as standard, and higher speeds up to 8x available, to produce high-quality replays and specialty program effects. The camera uses ultra-high-precision alignment technology to realize three 4K sensor on a new prism. This allows the support of the next-generation ITU-R BT.2020 broadcast standard’s widened color space for future-proof masters or post production options for today’s productions, shown on tomorrow’s 4K services. Direct attachment of B4 HD lensesStandard large-format B4-mount lenses mount directly onto the HDC‑4300. This gives broadcasters the flexibility needed for live sports broadcasts: 4K capabilities while maintaining their customary HD-lens operating styles. SZC-4001 SoftwareSony’s SZC-4001 software package (sold separately) allows broadcasters to take advantage of 4K capabilities. Super Slow Motion (up to 8x) at HD ResolutionThe SZC-4002 software package (sold separately) enables the system to shoot full HD (1920 x 1080) at frame rates up to 479.52/400 fps, as well as 59.94/50, 119.88/100, and 179.82/150 fps. Users can save these high-frame-rate shots to Sony’s PWS-4400 multiport 4K/HD Live Server. HD/4K Live Production for Sports  The HDC-4300 accepts the same configurations as existing 4K live systems. A BPU-4000 baseband processor unit receives the camera signals via SMPTE fiber and connects to an HDCU-2000 or 2500 camera control unit. This provides power and full intercom, tally, and return capabilities.Users can seamlessly blend an HDC-4300-based system with existing HDC Series camera systems. The HD signals from the HDC Series cameras and from the new camera system can be adjusted to match colorimetry. The addition of other 4K products, such as the PWS-4400 multi-port 4K/HD Live server, a multi-format switcher capable of real-time 4K signal processing based on the MVS-8000X, and Sony’s new BVM-X300 4K OLED or PMW-X300 4K LCD monitors create an end-to-end 4K live production solution. HDC-4300 – additional features:• HD cut-outs – two full HD images to be cut out from the 4K picture in real-time including a selectable zoom and perspective mode.• Many of the Picture adjustment functions of HDC Series cameras are supported by the HDC-4300 system• Dynamic focus (4K focus-assist function) – a focus point can be displayed on the viewfinder with a marker in 4K mode for easy focusing.• Auto lens aberration compensation 2 (ALAC2) function• Color reproduction adjustment functions• Gamma table selection• User gamma function• Natural skin-tone detail function• Knee saturation function• Low-key saturation function The HDC-4300 4K/HD live camera system is planned to be available in summer of 2015.

Wildlife Photography


Wildlife Photography
In his new book, wildlife photographer and Tech Tips guru George Lepp shares lessons learned in a lifetime of photography
By George D. Lepp And Kathryn Vincent Lepp, Photography By George D. Lepp


When I’m away to teach or photograph elsewhere, I feel that I’ve somehow abandoned my responsibility to witness the progression of the extended animal families at home. I wonder what has happened to that skinny fox that could catch, but never hold onto, a scolding squirrel. Did the doe with the broken foreleg escape the mountain lion? I think of the tiny, wide-eyed, newborn spotted fawn we found hidden under a shrub in the yard early one June. I remember the big red mother bear, gracefully balanced on the deck rail, sipping from the hummingbird feeder while her eager cub bounced about in a nearby tree.

I’ve been seriously pursuing wildlife and wildlife photography for over 40 years now and have developed a pretty large body of work featuring large and small mammals, insects, birds and fish. For decades, others have been using my wildlife photographs to tell their own stories—to illustrate their natural science books, sell their products or convey particular sentiments on a calendar—but the market for stock photography is changing. Images of just about every thing and every place can be purchased for literally pennies over the Internet. So I don’t really need to keep taking more wildlife shots, but I just can’t stop taking those pictures.

I still get a thrill when I come across a colony of tiny pikas and have an afternoon to spend with them as they run about, gathering grasses and wildflowers, calling to each other, sitting up to take my measure. Watching them engage in their busy lives is more compelling to me than trying to capture another ultimate pika shot, but still I put on the 500mm lens and the 2x extender and set it all up on a sturdy tripod. These days, I’m as likely to take video as stills, but either way there’s probably no financial reward for the afternoon’s work with the pikas.

So why bother? I do it because their habitat is so threatened, and because it’s increasingly rare to find them. I do it because I want to see their bright eyes and hear their sharp calls. I want to understand what they do and why they do it. I want to know them, every one of them. And I want you to know them, too.

In this book, Wildlife Photography: Stories From The Field (Lark Books, 2010), Kathy and I have gathered up my favorite wildlife images—my personal trophies—and Kathy has coupled these images with the stories of how they came to be. She writes in three voices: mine, her own and the subject’s. To ignore the greater context of the subject’s story would be disrespectful; to construct that narrative, we drew on our own observations and experiences, as well as the knowledge of others.

When I started my journey to becoming a nature photographer some 40 years ago, there were few competitors. Now, the natural landscape is a very crowded playing field, and it’s harder than ever to capture a unique image. In my more cynical moments, I see us all on the same circuit, moving through parks and mountain passes, along the coasts and through the river valleys, seeking the same subjects. When one photographer stops suddenly, the line behind him or her crashes; I imagine tripods and bodies in photo vests, all piled up like pick-up sticks.

Over the months that Kathy and I worked to put this book together, we had many discussions about what lies in store for young nature photographers in the years ahead. I feel very fortunate to have entered the field of nature photography at a time when subjects, and opportunities to photograph them, were abundant. But am I done now? No way! I want to go back to every place depicted on these pages and do it all over again. With all the technical and creative power offered by today’s digital cameras, image-stabilized lenses, and capture and composite techniques, I have a renewed urgency to document the wildlife I love, and I hope that talented younger photographers will find the impetus, inspiration and resources to do the same. To the next generation of nature photographers, I say please do it better than I did. Please focus on the challenges faced by our environment and shout them to the world. Please seek out the grace, beauty and purpose of each creature that calls to you, and document that life for posterity. Please join the line of nature photographers who have gone before you, put your tripods where theirs stood and contribute your vision to the field of wildlife photography. And, please, as long as I’m standing, save me a place in the queue.

Arctic Fox

Foxes, in general, are difficult to photograph because they’re constantly on the move. Whether it’s the beautiful red foxes that visit our Rocky Mountain Colorado home every day or the amazing Arctic foxes in winter white, they’re just busy, and they rarely stop to pose for a photograph. We got lucky with a pair of Arctic foxes. We spotted them looking for food—or something—within a heap of ice alongside Hudson Bay. After checking the area for polar bears, we left the protection of our tundra buggy and got into position at ground level. The foxes were completely unafraid of us; they moved quickly around the area, jumped up onto chunks of ice the size of boulders and played with one another. The lens had to be on them constantly so that the smallest opportunity for a good composition wasn’t missed.


We watched; they did what foxes do, and we waited for the perfect shot and hoped we wouldn’t miss it. Shooting subjects in snowy scenes can be a challenge, but there’s an advantage to photographing white animals on white ground; you can expose for the bright white tones, and the sunlight bouncing off the snow actually fills the shadows and lights the eyes of the subject like a built-in reflector. Make sure, though, that the white is actually rendered white. If you go with the exposure your meter suggests, you’ll get gray snow.

When calculating exposure for white on white, you have to seek the place where white is truly white, with detail. In the digital realm, consulting the image file’s histogram on the LCD monitor is the answer to this problem. Set your exposure manually to capture the brightest area of snow in the scene (one to two stops underexposed) and check the resulting histogram. If it shows image data up against the right edge, reduce your exposure further until there’s space between the end of the data display curve and the right edge of the graph.


Dolphins
When it comes to photographic effort versus actual results, my success ratios with dolphins are pretty low. Penguins are even harder to capture when they’re in the water. The problem is the same in each case: They disappear beneath the surface, then leap out without warning in a fast arch, then disappear again. How can you be ready?

The problem is the same in each case: They disappear beneath the surface, then leap out without warning in a fast arch, then disappear again. How can you be ready?

If a large pod of leaping dolphins crosses in front of your boat, you have a brief chance to capture their form, their behavior, their spirit and their beautiful environment, all at once. It’s magical.

Zebras
Two things keep me coming back for more zebra shots. First, their amazing stripes just say, "Look at me!" And, better yet, no two animals have the same pattern. Second, they tend to line up in a row, juxtaposing those flashy designs in combinations that range from aesthetic to chaotic. And a row of anything shouts “panorama” to me.

The idea of creating a multiple-image composite panorama of moving animals can be a little daunting. Add to that the complexity of the zebra’s patterned pelage, and you might think matching all those seams would be impossible. Although zebras are often very animated, with the youngsters tearing about and the males picking at each other in some kind of conflict, when the group comes to a waterhole or great feeding location, differences are set aside; everyone shares in the bounty and, best of all, they position themselves attractively in a manner designed to protect the entire group from danger. 

Before you work on zebras in Africa, you’ll want to practice your panorama capture techniques so you can move quickly. Overlapping each photograph in the sequence by 50% will give you plenty of information for compositing the images, and those complicated stripes are actually an advantage because they provide an abundance of specific details to assist you in matching the seams. Still, a panorama of moving animals will defy most automated compositing software; you’ll most likely need to assemble your panorama manually in Photoshop. And there’s more you can do with zebra images, of course. 

Close-up portraits and the interactions of big males, mares and foals, and adolescents all offer the usual appeal, enhanced and energized by those incredible patterns.
