Samsung NX20: First Impressions

On a recent trip to Samsung's Seoul headquarters I got the opportunity to use the new NX20, and get a feel for how it performs. I only had a short time with a pre-production camera, but overall, my impressions of its handling and performance are very positive. Certainly, anyone who has used and liked the NX20's predecessor, the NX10, will find little to complain about in the new model, and much that is very familiar. 

Where it sits in the lineup

The NX20 sits at the top of Samsung's totally refreshed NX lineup, above the NX210 and NX1000. All three are based around the same 20MP CMOS sensor and all offer eight frame-per-second continuous shooting and Wi-Fi-connectivity and control, but the NX20 includes a handful of feature unique within the range.

The NX210 doesn't include a viewfinder, nor is its OLED screen articulated - making it less expensive - but it steps forward from the NX200 by adding Wi-Fi, faster continuous shooting and the option to use a cable shutter release and proprietary external microphone. The NX1000 is less expensive still, and features a plastic body, VGA rear screen and retractable kit zoom. Here we'll mainly look at the features of the NX20 that it offers over these other cameras, since they are what makes it the range-topping model.

Articulated 'Clear' AMOLED display

Externally, the most obvious difference between the NX20 and its predecessor is an articulated rear screen. The 3" AMOLED display offers VGA-equivalent resolution in the now-familiar Samsung 'pentile' arrangement, giving a perceptual resolution higher than its relatively-low dot-count of 614k dots might suggest. It's the same underlying OLED panel that we've seen on all of the NX models so far, and as such it is contrasty and detailed, with a wide viewing angle. Articulation makes the screen that bit more usable, of course, especially when it comes to shooting video or stills from high and low angles.

  

The NX20's display itself might offer the same specification as the previous-generation NXs, but there is one significant design change - the air-gap between the display and protective covering has been eliminated by filling it with a UV-cured resin that reduces internal reflections to improve contrast and visibility in bright lighting conditions. Samsung claims that this 'Clear AMOLED' display offers a 20% improvement in contrast ratio and, although I wasn't able to test the NX20 alongside an NX10, it does seem to deliver a genuine benefit in terms of clarity, and I was impressed by how usable the screen is in direct sunlight.

Aside from the articulated screen, the NX20 handles in a very similar way to the NX10. The main difference from more recent cameras like the NX100 and NX200 the provision of an electronic viewfinder, but the grip too has been changed - it is now more pronounced, making the NX20 a generally 'rounder' and more comfortable camera to hold. Where the NX200 looks sharp and stylish, the NX20 looks softer, curvier and more welcoming.

 

The softer, more rounded design belies a serious feature set though - 8fps at full-resolution and an electronic first-curtain shutter allowing a maximum shutter speed of 1/8000 sec with reduced shutter lag (40 milliseconds) are both pretty impressive. These improvements will be welcomed by enthusiast photographers, as will a new 'Custom Mode' feature that allows you to save up to three shooting setups as custom shooting modes. These can then be recalled, either from the Smart Panel, or from a dedicated 'C' position on the exposure mode dial.

Custom shooting modes can be named using an on-screen text-entry dialog or if you're in a hurry, saved automatically by date. Existing features have been given a refresh too - we've been very impressed by the evolution of Samsung's 'iFn' on-lens function feature in the NX range, and iFn 2.0 adds even more options. It's great to see an electronic spirit level added to the NX20, too, which indicates roll and pitch.

The 100% coverage electronic viewfinder is the key differentiator between the NX20 and the NX210, and although I was using an early sample which I was told may not have been up to production quality, I enjoyed using the finder for image composition. The resolution of the NX20's EVF is SVGA (800 x 600 pixels, 1.44M dots), and in my experience remains pleasantly contrasty and detailed in all but the strongest side light (where like the NX10, the screen image is prone to 'flaring out').

The only serious annoyance that came out of my short time with the NX20 was related to the position of its direct movie recording button. I shot a lot of movie clips on the NX20 when I used it, but most of them were recorded accidentally thanks to the prominence of the movie record button on the upper right shoulder of the camera.

 

Apart from this minor irritation though the NX20 is, like its predecessor, a pleasant camera to use, with an interesting and competitive feature set. The addition of Wi-Fi is of huge significance to Samsung as a step on the way to achieving its stated aim of creating a generation of 'connected cameras' and refinements like increased continuous shooting speed and display articulation add real benefit in day to day shooting.

I wasn't able to save (or even closely examine) images from the NX20 that I used in Korea, but there is nothing to suggest that image quality won't be broadly in line with our expectations based on experience with the NX200, which uses the same 20MP CMOS sensor. We should be receiving an NX20 shortly, and we will publish a more in-depth assessment and sample images as soon as possible.

Modern Kitchen Design

Sometimes referred to as the heart of the home, the kitchen is a place to prepare and cook food and, depending on the size, can be used to eat and entertain guests. In Ancient Greek homes, this room was a central open air patio but it was not until around 1800 that the stove, which enclosed fire completely, made cooking indoors possible. As technology advances, so do kitchens' design and efficiency. The introduction of the kitchen island has lent more flexibility to the positioning of the kitchen cabinets and kitchen sink, and helped make open plan kitchens and dining rooms a reality. 

MG Icon Concept preview

 At the 2012 Beijing Auto Show MG will present the Icon Concept, a midsize SUV with a design inspired by the brand’s classic model.

At the upcoming Beijing Show (25 April – 2 May 2012), MG is unveiling the Icon Concept, which – as the name suggests – adopts a design influenced by MG’s heritage.

More specifically, the front end with the round headlights and chromed grille and the fastback rear end have some reminiscences of the MGB GT of the 1960s.

The interior is more futuristic and features a symmetric dashboard with integrated LCD displays.

Among the main design elements are the metal-finished stripes that run in the door panels and along the lower area of the dashboard and the three circular air vents at the center of the dashboard, visually recalled by the steering wheel center piece.

The rear seats can be folded to leave space for a flat cargo area.

According to the first information the car – developed by SAIC designers – is based on the Roewe 350 and could be launched on the market with a 1.5 liter gasoline engine and a choice between front- and all-wheel drive transmission.

We report the first low resolution renderings of the Urus, the new SUV Concept set to debut as a static model at the upcoming Beijing Show.

The design study has an aesthetic language similar to the latest creations of the company, with aggressive, angular shapes and sharp lines.

The dimensions are generous (4.99 x 1.99 x 1.66 meters), and the proortions are close to those of the BMW X6, compared to which the Urus is 11 cm longer, 1 cm wider and 4 cm lower.

The exterior features distinctively sloped shoulder line, complemented by a descending roofline, while the stance is enhanced by the muscular rear shoulders and the 24-inch wheels.

The adoption of the current design language – already expressed with the Estoque and the Aventador, is evident in many details, including the color scheme, the carbon-fiber details, the Y-shaped headlights and the angular front air openings.

Active aerodynamics elements include an adjustable front spoiler, a variable ride height system and an adaptive rear wing.

The interior features four individual seats, a carbon-fiber trimmed dashboard and a touch screen on the center console.

 

The name Urus refers to the ancestor of domestic cattle. According to the first information, the car is planned to be produced in approx. 3,000 units per year.

Best Home Design for Modern Office Design

 Best Home design can be applied both for residential or office, this time I will share you several best home ideas for designing  an office. Most of best office design usually used modern architecture and interior design, but actually the most difficult on designing an office is how to choose the best office goods and then combining the goods with the interior theme.

Office environment usually dominated with goods with similar vendor, such as this best home office design with PCs from Mac. People who use PCs may or may not care about the design of their products. Mac users always care. Apple is known for the innovative design of everything it creates from the iPod to the ultra-thin Macbook Air. Not to be outdone by the creators of the products, Mac users challenge themselves to set up their equipment in creative, aesthetically pleasing ways. In other words, Mac users create home and office setups that reflect just how cool they are for using a Mac.

Wireless Electricity (WiTricity)

 Understanding what WiTricity technology is—transferring electric energy or power over distance without wires—is quite simple. Understanding how it works is a bit more involved, but it doesn’t require an engineering degree. We’ll start with the basics of electricity and magnetism, and work our way up to the WiTricity technology.

Electricity: The flow of electrons (current) through a conductor (like a wire), or charges through the atmosphere (like lightning). A convenient way for energy to get from one place to another!

 Magnetism: A fundamental force of nature, which causes certain types of materials to attract or repel each other. Permanent magnets, like the ones on your refrigerator and the earth’s magnetic field, are examples of objects having constant magnetic fields.

Oscillating magnetic fields vary with time, and can be generated by alternating current (AC) flowing on a wire. The strength, direction, and extent of magnetic fields are often represented and visualized by drawings of the magnetic field lines.

Electric current flowing in a wire creates a magnetic field

 As electric current, I, flows in a wire, it gives rise to a magnetic field, B, which wraps around the wire. When the current reverses direction, the magnetic field also reverses its direction.

Representation of the magnetic field created when current flows through a coil

 

The blue lines represent the magnetic field that is created when current flows through a coil. When the current reverses direction, the magnetic field also reverses its direction.

Electromagnetism: A term for the interdependence of time-varying electric and magnetic fields. For example, it turns out that an oscillating magnetic field produces an electric field and an oscillating electric field produces a magnetic field.

Magnetic Induction: A loop or coil of conductive material like copper, carrying an alternating current (AC), is a very efficient structure for generating or capturing a magnetic field.

If a conductive loop is connected to an AC power source, it will generate an oscillating magnetic field in the vicinity of the loop. A second conducting loop, brought close enough to the first, may “capture” some portion of that oscillating magnetic field, which in turn, generates or induces an electric current in the second coil. The current generated in the second coil may be used to power devices. This type of electrical power transfer from one loop or coil to another is well known and referred to as magnetic induction. Some common examples of devices based on magnetic induction are electric transformers and electric generators.

Energy/Power Coupling: Energy coupling occurs when an energy source has a means of transferring energy to another object. One simple example is a locomotive pulling a train car—the mechanical coupling between the two enables the locomotive to pull the train, and overcome the forces of friction and inertia that keep the train still—and, the train moves. Magnetic coupling occurs when the magnetic field of one object interacts with a second object and induces an electric current in or on that object. In this way, electric energy can be transferred from a power source to a powered device. In contrast to the example of mechanical coupling given for the train, magnetic coupling does not require any physical contact between the object generating the energy and the object receiving or capturing that energy.

A transformer uses magnetic induction to transfer power between its windings

 An electric transformer is a device that uses magnetic induction to transfer energy from its primary winding to its secondary winding, without the windings being connected to each other. It is used to “transform” AC current at one voltage to AC current at a different voltage.

Resonance: Resonance is a property that exists in many different physical systems. It can be thought of as the natural frequency at which energy can most efficiently be added to an oscillating system. A playground swing is an example of an oscillating system involving potential energy and kinetic energy. The child swings back and forth at a rate that is determined by the length of the swing. The child can make the swing go higher if she properly coordinates her arm and leg action with the motion of the swing. The swing is oscillating at its resonant frequency and the simple movements of the child efficiently transfer energy to the system. Another example of resonance is the way in which a singer can shatter a wine glass by singing a single loud, clear note. In this example, the wine glass is the resonant oscillating system. Sound waves traveling through the air are captured by the glass, and the sound energy is converted to mechanical vibrations of the glass itself. When the singer hits the note that matches the resonant frequency of the glass, the glass absorbs energy, begins vibrating, and can eventually even shatter. The resonant frequency of the glass depends on the size, shape, thickness of the glass, and how much wine is in it.

Resonant Magnetic Coupling: Magnetic coupling occurs when two objects exchange energy through their varying or oscillating magnetic fields. Resonant coupling occurs when the natural frequencies of the two objects are approximately the same.

WiTricity Technology: WiTricity power sources and capture devices are specially designed magnetic resonators that efficiently transfer power over large distances via the magnetic near-field. These proprietary source and device designs and the electronic systems that control them support efficient energy transfer over distances that are many times the size of the sources/devices themselves.

The WiTricity power source, left, is connected to AC power. The blue lines represent the magnetic near field induced by the power source. The yellow lines represent the flow of energy from the source to the WiTicity capture coil, which is shown powering a light bulb. Note that this diagram also shows how the magnetic field (blue lines) can wrap around a conductive obstacle between the power source and the capture device.
