    • 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.

Motion-Blur Wildfire Photography

Motion-Blur Wildfire Photography

I remember taking an endless amount of big cat portraits until a fellow photographer aptly pointed out that my portfolio had little diversity to it. Upon asking him what he suggested, the idea of Motion Blur Photography came up and he proceeded to give me a few basic ideas to keep in mind. These techniques that I learnt are great to try out for yourself as they will bring a whole new aspect to your photographic repertoire.
Motion Blur is primarily about capturing a scene in which an object is frozen still, whilst everything around it is blurred in motion. From a wildlife perspective, you might have seen images, such as this one below, of animals frozen in mid stride or flight whilst the background behind them is heavily blurred. If you wish to try them out when you are next on safari, or at home then take into account these basic pieces of advice below.
I have found the biggest things to remember in motion blur photography are:

Being prepared to take the shot:
Wildlife motion blur photography is different to staged motion blur shots in that you only get one chance to grab the shot. When specifically looking to capture motion blur shots, make sure you camera settings are where you want them, your stabilisation is ready and waiting and that your are conscious of which direction the animals are going to be moving in. It also helps to get yourself in a comfortable, yet flexible position to track the animal.

Correct camera settings – Shutter Priority:
By using the shutter priority on your camera, you are in control of how long your shutter is open for. In late afternoon or early morning light, I typically set my camera to 1/60s. This slightly slower shutter speed allows for the shutter to be open long enough to capture the moving image, but is also short enough to make sure that an excess of light doesn’t get in.

Stable Tracking:
A Bean bag, Wimberley head or Tripod is critical to achieve a shot which makes the subject matter crisp against the blurred background. Once you are in position and animals are moving, begin tracking them through your viewfinder and then click your shutter open. In looking through your viewfinder, pick a spot on the animal (eye, shoulder, head, etc) and keep a navigation point on this spot. Alternatively you can also shoot a sequence of rapid photographs whilst tracking the animal, but always remember to begin tracking the animal before you open the shutter and keep following it until after the shutter has closed.

 
A Lower ISO:
Lowering your ISO impacts the sensitivity of your digital camera’s image sensor. The higher the ISO, the more sensitive it is to light, whilst the lower the ISO the less sensitive it will be. By choosing a low number, 200 or 400, you will be able to have your shutter speed open for longer without letting in too much light.  This in turn allows for more of the background to unfold in the image.

Other Ideas:
You can use the above settings and twist your cameras lens to achieve a different type of motion blur.  In the below photograph, I went from tight to wide in the duration of the shutter being open. The effect is of two different shots in one. This type of shot also works well if you have an object or animal moving towards you.
 Despite not being wildlife focused, this video reiterates some of the interesting motion blur ideas and techniques discussed above.


Motion blur photography is a challenging technique that is, more often than, not based on quite a large amount of luck. I have taken hundreds of pictures to only have two or three come out nicely. So if at first you don’t succeed, keep at it! If you have any suggestions or other ideas about motion blur photography, please write them down in the comments section below as I would love to learn more.
