* 12.4- D2xs Offers Unique Combination of Extraordinary , High-Speed and High- in a Single
* Internal and External Refinements Make D2xs a Commendable Successor to ’s Flagship D2x Camera

MELVILLE, N.Y., June 1 — (R) (http://www..com), the world leader in , today introduced the new D2xs(TM) professional camera, incorporating an impressive range of refinements that improve overall camera performance and enhance the user experience. The D2xs shares many performance and design innovations with the current and highly successful D2x camera, including the 12.4 million DX format that renders with high and sharp detail, necessary for demanding professional assignments. The D2xs also hosts a range of upgraded features that make operation significantly more responsive — including refined performance that makes for easier composition when shooting in ’s exclusive High-Speed Crop mode, a new 2.5 inch LCD with a 170-degree wide viewing angle, individually calibrated at the factory to ensure consistent color fidelity, significantly increased life and a wide range of firmware enhancements.

With its numerous refinements, the D2xs is truly equipped to meet the widely varied demands of today’s professional who strive to create that push the boundaries of what’s possible. Not only does the camera successfully combine high , speed and quality, but it also incorporates exclusive technologies that enable unfettered creativity. Options such as the WT-2A Wi-Fi transmitter achieves full wireless remote camera control and transmission, while the revolutionary i-TTL Speedlight technology included in the D2xs ensures radical new possibilities in creative lighting.

“Increasingly, professional have chosen the D2x as their primary workhorse camera due to its remarkable performance and versatility, making it ’s best selling professional camera. With the introduction of the D2xs, has built upon the proven performance of its predecessor and added new technologies and refined features that will
offer professionals an enhanced overall experience,” said Edward Fasano, general manager for Marketing, Products, Inc. “The D2xs is poised to become the next of choice among professional .”

Versatility Refined

Many of the that made the D2x such a success have been retained. The D2xs is capable of capturing 12.4 JPEG or RAW (NEF) at a rate of up to 5 frames per second in continuous shooting mode, and maintains a rapid start-up time, the world’s shortest shutter release time lag of just 37ms, as well as a blackout time of just 105 milliseconds. The D2xs also inherits the popular High-Speed Crop mode that uses a specific central area of the sensor to capture 6.8 at an incredible rate of up to 8 frames per second. A newly developed in the D2xs automatically superimposes a mask over the cropped area within the while in the High-Speed Crop mode, for easier and more confident composition.

The D2xs features ’s acclaimed Mutli-CAM2000 high-speed AF system, with eleven autofocus sensors — nine of which are cross-type and placed in the rule of thirds layout. The D2xs offers improved subject acquisition and tracking as well as a new option for controlling the duration of Lock-On(TM) focus tracking, making it easier to adjust for shooting
different types of scenes and action.

New Image Rendering and Menu Options

With a combination of powerful image-processing technologies and ’s exclusive 1,005 3D-Color Matrix Metering II, the D2xs makes it possible to capture beautiful 2.4- that meet and exceed professional ’ needs for larger files that are rich in detail, color and smooth tonal range. The D2xs has also been refined so demanding can take advantage of ’s 3D-Color Matrix Metering II even in the High-Speed Crop mode. Professional will appreciate the ability to select Adobe RGB in any of the three color modes — making it possible to work with a wider range of colors to match highly diverse assignments and workflow environments, while ideally complementing the NEF file. In-camera creative possibilities are extended even further through the addition of a new Black & White (sRGB) color mode.

shooting in RAW (NEF) will have the ability to shoot in and still retain the color information in the RAW image data, allowing them to easily reverse a image to color using ’s new Capture NX software.

RAW and JPEG taken using the D2xs can be trimmed within the camera to produce of reduced display sizes ranging from 640 x 480 to 2,560 x 1,920 pixels. The resulting smaller files can help improve workflow efficiency by eliminating the time required to download and perform software editing within a computer.

New ISO sensitivity options offer greater convenience to who work under constantly changing lighting conditions such as weddings. A new Auto ISO feature allows to maintain a specific while letting the camera automatically select an appropriate ISO setting, within a predefined range of sensitivities, based on the existing lighting conditions. This feature helps achieve optimum exposure while freeing the to concentrate on composition. ISO sensitivity can also be manually set between ISO-equivalent 100 and 800 in increments of 1/3 EV, or boosted using HI-0.3, HI-0.5, HI-0.7, HI-1 or HI-2 settings when high sensitivity is a priority. The 3 settings between 800 and HI-1 are newly added to give the D2xs finer control over sensitivity.

Refined Ergonomics and Design

The D2xs body is consistent with the exterior styling of the D2-series, adopted from a design created by famed industrial designer, Giorgetto Giugiaro*. The body is proportionate and well balanced, with a well designed interface that is intuitive and seamless.

The D2xs improves upon its predecessor’s energy efficient design, and when combined with the newly developed high-energy EN-EL4a rechargeable lithium-ion , the camera boasts an unprecedented 3,800** shots per charge. ’s highly sophisticated, real-time Fuel Gauge system in the D2xs allows to determine the precise level of remaining charge, number of shots taken per charge and the overall life of the — all at the touch of a button.

A new 2.5-inch, 235,000 dot LCD monitor in the D2xs allows a 170-degree wide viewing angle, and is individually calibrated at the factory to ensure consistent color fidelity. The D2xs also features a new color scheme for menu displays.

Expanded Software Options

The D2xs features a unique Image Authentication feature that, when used with ’s new Image Authentication Software, marks the authentication of an image captured by the camera and can determine whether or not it has been altered since capture. Image data is a critical link in the “chain of evidence” for verifying image authenticity, and D2xs’s hardware and software-based image authentication solution allows easy, secure authentication of for a wide range of requirements. The softwareenables verification of JPEGS, TIFF and NEF (RAW) taken with the D2xs.

A new remote control software called Camera Control Pro is also available for the D2xs, enabling unprecedented remote control operation of many camera functions from a personal computer. Camera Control Pro software is the next generation of camera control software, previously bundled with ’s Capture 4 software, and features substantial advanced features that offer limitless creativity to who need to control their camera remotely. Camera Control Pro can control the D2xs remotely tethering a high-speed USB cable or optional WT-2a wireless transmitter.

The D2xs is also compatible with ’s soon-to-be-released Capture NX(TM) software — a highly versatile yet elegantly simple editing solution that provides easy, yet powerful and visually intuitive image-editing and enhancement tools. With Capture NX, will be able to tap into the full potential of D2xs’s RAW (NEF) files, while also apply powerful image processing and editing tools to JPEG and TIFF files.

The D2xs will be available from authorized retailers in late June for an estimated street price of $4699.95***. For more information, please visit http://www..com

20 Sep 08 The Magic Behind Digital Camera

Author: Harry Rockwell

A , as opposed to a or videotape camera, uses an to transform (or video) into electronic data. Modern are typically multifunctional and the same device can take , video, and/or sound.

In 2005, are starting to push traditional cameras out of many markets. Shrinking device sizes have recently allowed miniaturized to be included in multifunctional devices, such as cell phones and PDAs.

Classification

can be classified into several groups:

* Professional such as those used in television and movie production. These typically have multiple sensors (one per color) to enhance and color gamut. Professional usually do not have a built-in VCR or .

* Camcorders used by amateurs. These are a combination of camera and VCR to create an all-in-one production unit. They generally include a to record sound, and feature a small LCD to watch the video during filming and playback.

Still cameras

are generally characterized by the use of and USB or Fire Wire for and transfer.

Most have a rear LCD for reviewing . They are rated in ; that is, the product of their maximum dimensions. The actual transfers to a host computer are commonly carried out using the USB mass device class (so that the camera appear as a drive) or using the Transfer Protocol and its derivatives.

All use a (for Charged Coupled Device) which is a chip comprised of a grid of phototransistors to sense the light intensities across the plane of focus of the .

There has recently been some application of a second kind of chip, called a (Complementary Metal-Oxide Semiconductor) sensor, and this chip is often differentiated from a proper in that it uses less power and a different kind of light sensing material, however the differences are highly technical and many manufacturers still consider the chip a charged coupled device. For our purposes, a chip sensor is a .

* Standard : This encompasses most . They are characterized by great ease in operation and easy focusing; this design allows for limited motion capability. They have an extended depth of field.

This allows objects at multiple depths to be in focus simultaneously, which accounts for much of their ease of focusing. It is also part of the reason professional find their flat or artificial-looking. They excel in landscape and casual use.

* typically have a sensor nine times larger than that of a standard , and are targeted at professional and enthusiasts. They resemble ordinary in most ways, with replaceable and lens components, which give the user maximum control over light, focus and depth of field.

They are also bulkier and more expensive than their casual-use oriented counterparts. They are superb for portraiture and artistic because they can be customized for various applications with a comprehensive range of exchangeable .

Professional modular systems

High-end backs used by professionals are usually separate devices from the which they are used with. (This is because most of the large- and medium-format camera systems in professional use at the time that digital capture overtook as the professional’s medium of choice were modular in nature, i.e. the had multiple , viewfinders, winders and backs available for use with it to fit different needs.)

Since the first backs were introduced there have been three main methods of “capturing” the image, each based on the hardware configuration of the particular back.

The first method is often called “Single Shot,” in reference to the number of times the camera’s sensor is exposed to the light passing through the .

Single Shot capture systems use either one with a Bayer filter stamped onto it or three separate CCDs (one each for the primary additive colors Red, Green and Blue) which are exposed to the same image via a beam splitter.

The second method is referred to as “Multi-Shot” because the sensor is exposed to the image in a sequence of three or more openings of the lens aperture. There are several methods of application of the multi-shot technique.

The most common originally was to use a single with three filters (once again red, green and blue) passed in front of the sensor in sequence to obtain the additive color information.

Another multiple shot method utilized a single with a Bayer filter but actually moved the physical location of the on the focus plane of the lens to “stitch” together a higher image than the would allow otherwise. A third version combined the two methods without stamping a Bayer filter onto the chip.

The third method is called “Scan” because the sensor moves across the focus plane much like the sensor of a desktop scanner.

These CCDs are usually referred to as “sticks” rather than “chips” because they utilize only a single row of pixels (more properly “photosites”) which are again “stamped” with the Bayer filter.

The choice of method for a given capture is of course determined largely by the subject matter. It is usually inappropriate to attempt to capture a subject which moves (like people or objects in motion) with anything but a single shot system.

However, the higher color fidelity and larger file sizes and available with multi-shot and scan-backs make them attractive for commercial working with stationary subjects and large-format .

Webcams

* Webcams are attached to computers, used for or other purposes. Webcams can capture full-motion video as well, and some models include or ability.

These devices range in price from very inexpensive to expensive higher-end models; many complex webcams have a servo-controlled base capable of tracking facial motion with the help of software.

Interpolation

Image color or interpolation is used unless the camera uses a beam splitter single-shot approach, three-filter multi-shot approach, or Foveon X3 sensor.

The software specific to the camera interprets the information from the sensor to obtain a full color image. This is because in digital , each must have three values for luminous intensity, one each for the red, green, and blue channels. A normal cannot simultaneously record these three values.

The Bayer filter pattern is typically used. A Bayer filter pattern is a 2×2 pattern of light filters, with green ones at opposite corners and red and blue elsewhere.

The high proportion of green takes advantage of properties of the human visual system, which is determines brightness mostly from green and is far more sensitive to brightness than to hue or .

Sometimes a 4-color filter pattern is used, often involving 2 different hues of green. This provides a wider color gamut, but requires a slightly more complicated interpolation process.

The luminous intensity color values not captured for each can be interpolated (or guessed at) from the values of adjacent pixels which represent the color being calculated.

In some cases, extra is interpolated into the image by shifting photosites off of a standard grid pattern so that photosites are adjacent to each other at 45 degree angles, and all three values are interpolated for “virtual” photosites which fall into the spaces at 90 degree angles from the actual photosites.

Connectivity

Many can connect directly to a computer to transfer data. USB is the most widely used method, though some have a Fire wire port.

Integration

Some devices, like mobile phones integrates . Mobile phone cameras are much more sold than standalone digital ones.

need to store data. The higher one goes in size, the more will be needed. Cameras use a removable card to store data, but the cheapest and smallest cameras may simply use fixed internal instead. Some cameras come with inbuilt as well.

Autonomous devices

An autonomous device, such as a , operates without need of a computer. The camera connects to the printer, which then downloads and prints its . Some DVD recorders and television sets can read cards too.

18 Sep 08 Top 20 Questions to Consider When Buying a Digital Camera

Author: aldrin garcia

My top 20 key questions to ask yourself when buying a .

1. How many “” /?

Once and for all, at least to me, you have to get the highest your money can buy at the time you buy. Period.

2. Who made the lens?

Most cameras will give you an idea where the lens was made just by looking at the front of the lens. Know if the lens of your camera came from a reputable company like , Zeiss, , Etc… Lens quality is one of the most important factors you should consider especially if you’re going to use it for commercial, technical or scientific purposes.

3. Will I need interchangeable ? How many are available for my specific camera in mind?

Having the option of interchangeable gives you the freedom to experiment with different kinds of focal lengths. Although some P&S (point and shoot) cameras can rival ’s with a generous range for a non interchangeable lens system.

Also note the number of available for use with your specific camera because of flexibility reasons. You can practically cover the entire “ range” with interchangeable versus modest ranges on non interchangeable lens systems or P&S cameras.

4. Does it have a capability? What’s the range?

Almost all applications that I listed above will need some form of zooming in (telephoto) or out (wide angle), especially if you don’t have the space to move around the object you are shooting.

For Landscape shots, wide angle shots are very common and appealing while zooming in on the details serves as a break and complements the wide angle shots.

For weddings and events, you need a because there will be times where you are limited by the shooting space and you will have a difficult time moving around. Its a good thing to know that you can do all sorts of framing without even moving from your position.

A nice will give you the efficiency and versatility in your , so my suggestion is to go for the longest range you can get (usually from a 7X to a 10X for Point and Shoots).

Also note the speed of zooming in or out as this will be a factor if you’re shooting events like weddings. You will fail to capture that “decisive moment” on a mediocre speed.

5. Does it have the provision to capture raw ?

Many will say you’ll need this feature if you want to have big prints from your . Although this is correct, the main reason why you will want this is because of the benefit it will give you…pure total control of your … from exposure, color, metadata, hdr and a lot more.

6. Can I attach an external ?

Having an external capability will give you the power and creative freedom to light your subjects any which way you like.

You can connect your to all sorts of lighting equipment thus giving you more options and versatility. This comes in the form of a hotshoe or a PC-Sync socket.

If your doesn’t have this feature, there is still hope because accessories called slaves are being sold by third party companies in different flavors that will also do the same job more or less.

7. Does it have a tripod socket?

Some of the most beautiful landscape that I’ve seen are undoubtedly made with a tripod, so this is a must have if you are planning to do this kind of .

The “ shots” in a wedding, still life and product shots, studio and fine art shots … all need a tripod for successful execution… so guess what happens if you don’t have a tripod socket?… You cannot effectively use a tripod!

8. Does it have automatic and manual focusing?

It will not be evident at first why you’ll need this especially if you’re just starting out in . But if you’re like me… A total control freak when it comes to cameras… and you really want to express your creative side, this is definitely a must have.

9. Can you attach filters to it? and what filter size?

Creative expression through special effects is just one of the many reasons that makes fun and interesting, and experimenting with filters is one creative pursuit you should try with your especially if you’re a beginner.

Always remember to ask if the particular you are eyeing for can handle filters and ask for the filter size. (To save you from buying the right filter with the wrong filter size) Please note that most should be able to to handle filters as most that come with it have a filter thread built into the lens.

Most P&S (point and shoot) normally doesn’t have a filter thread built-in and might need special accessories to accomplish this so you should check to know for sure.

Again, there are many third party accessories that you could buy to adapt filters to your P&S that don’t have this provisions. I’ll discuss all about this in a future post so watch for it. (Or subscribe to my announcement list (feed via email) so you’ll know when it’s up.

10. Can I upgrade the firmware?

The good thing about some manufacturers is that they keep on improving their even after they sold it to you… this comes in the form of a firmware upgrade.

Usually this involves an improvement on one or many features of a camera. Be sure that the you’re planning to buy has an easy way of upgrading its firmware. This comes in the form of either an easy download via the manufacturer’s website (find it and bookmark it now) or a FREE CDROM.

Another caveat - be sure to consider if a downgrade is also possible or available with your … Why is there a need a downgrade you ask?… Because, you may want to reinstall an earlier firmware… just in case you don’t like the results from a firmware upgrade.

Occasionally there’s a feature that will be removed by the upgrade that you failed to read about and you decided that you just want to keep that feature instead of a bunch of trivial upgrades from the new firmware. (Yes, I personally experienced this.)

11. Are there extra goodies or software that come with it?

Some people ignore the fact that you can save a lot of money just by doing a simple arithmetic. Did you know that you could actually get your for a lot less if you study the deals and offers on the marketplace?

If you buy a and it comes with software that you can really use… like photoshop, elements, or any other software for that matter, then you already saved some money you would otherwise spend. Some dealers will throw in lots of extras… If you just simply ask.

Always try to ask for these things that you’ll end up buying anyway if you don’t - like camera bags, extra , extra , cards, tripod, etc. Trust me… you will end up buying these things if you don’t ask for it on the deal. What have you got to lose? Simply ASK. Would you believe that I effectively lowered one of my cost by as much as 30%? Ask away.

12. Is there Local Support in your area?

Finding the answer to this one will give you a great benefit in the long run. Wouldn’t you sleep better at night because you feel that extra security - that in case there is something wrong with your , you can bring it in for repair at a moments notice?

Not knowing when your camera will be repaired (or if it even arrived at a distant repair facility) is one of the worst feelings a can have especially if you’re in the middle of a photoshoot or project.

13. What type of warranty does it have? Worldwide / Countrywide?

If you travel a lot its good to know that a countrywide or even better - a worldwide warranty can get your camera fixed wherever you are. Always bring the warranty card and glue it on your camera bag.

14. Does it have the ability to take video and audio?

I know, most DSLRs don’t have this function. But some non interchangeable lens DSLRs have it. This is a very useful feature to have if you’re on a project or photoshoot and want to document or record a procedure, a moment, or an idea that you would otherwise have trouble remembering or even writing. It’s always a good idea to bring a P&S camera backup that have this function.

The things that you could do with audio and videoclips on a photoshoot are only limited by your imagination… interviews, documentation, funny quips, training procedures, bloopers, etc..

15. Does it have a manual ?

is one of the most interesting aspects of . Its fun and fascinating to work with. Having this option puts the fun-o-meter way way up. In future posts, I will be discussing in detail so be sure to stay tuned.

16. How sensitive is it to infrared?

If you’re planning to make infrared or enter the exciting world of Infrared fine art then you’ll want to know if your can do it.

TIP: There is a simple way to test how sensitive your is to infrared using a very common device - a TV remote control. For P&S, you can aim the remote control towards the lens and gauge how bright the LED from remote is. This should give you an idea how sensitive your is to infrared. For DSLRs you will need to take shots of the LED and experiment a little or you can simply research or the particular you have in mind for other people’s experiences and thoughts about it.

17. How high is the ISO sensitivity? Is it manually adjustable?

ISO sensitivity is a term referring to the sensitivity of to light. In the world, it refers to the sensitivity of the in your in relation to the ISO standard used for .

The higher the ISO sensitivity of your camera the faster or better it can record a specific amount of light.

High ISO sensitivity is useful for taking better in dark settings… such as inside a church or at night. The higher the ISO setting, the more details you can capture of a dark scene.

One caveat - take note of the amount of noise a particular camera exhibits at higher ISOs. Some people like it and some don’t. Again, don’t be afraid to ask or do research on the noise characteristics of your in mind to see if this is the right choice for you.

18. How high or low can you set the shutterspeed? What are the minimum and maximum aperture settings?

Shutterspeed and aperture settings are the basic mechanisms that drive your camera and controls the amount of light that is exposed by the or .

You use high shutterspeeds in action shots and to prevent camera shake, and you use low shutterspeeds for movement effects and bulb or long exposures. You can check for these figures on the websites that I gave you in part 1. You can see it in the technical specifications for a particular camera.

A bulb or “T” function is a nice feature to have because you can take exposures for virtually very long periods of time. Another feature to have is if your camera has a remote control to use this bulb or “T” mode. This gives you the capability to take without holding your camera and adding to the “camera shake”.

With the subject of apertures, a small one (small aperture opening) lets you have a wider depth of field so your shots are sharp from near to far versus a large aperture (big aperture opening) where your shots have a narrow depth of field and appear “selectively focused”.

19. Does it have some form of an ?

New cameras coming out as we speak often have this feature. Simply put, an is some form of a mechanism built into the lens or the (depending on the manufacturer and their implementation) that basically prevents you from getting blurred when taking in low light or you are using a long or . Having this feature can mean the difference between a blurry (aka no !) to a usable one.

20. How close can it focus? Macro abilities?

The closer your camera can focus… the bigger the of an object you can take in relation to the image dimensions of the final … and the bigger the of the object… the more detail you can get. If you want to take of small objects such as flowers and fine details then this is a must-have.

That’s it. Whew.

Do you really have to go over all these questions?… Of course not, but even if you only study and ponder on half of them…and take the time… I promise you that one thing will surely happen…

You’ll be…

a lot smarter!

than when you first started asking these questions… ergo you’ll be in a better position to decide what to buy… Because you are now armed with the most powerful tool anybody can have

the power of information!

In any case, I hope you find as much value in these questions as many of my friends have and be able to get the camera of your dreams.

Enjoy!
