The camera and the influence of digital technology

In the study of digital camera is influenced by a variety of different sources for the collection, to give modern digital photographic capabilities. Some of these technologies are then advanced in special niches to create new scientific advances. One of the best examples of this exchange of digital technology is the CCD or charge-coupled device. This is the digital technology, the breakthrough for digital cameras have made ​​it possible.

When light strikes the CCDSurface, the electrons free to move and electrons accumulate in capacitors. These electrons are "counted" at regular intervals by a circuit to get the electrons from each point on the surface of the CCD. If all these measures are combined, the image can be instantly reproduced as a "virtual mosaic" of single point measurements. This is the image we see. The more points of measurement found on the CCD, the higher the "resolution" of the resulting image.

WhenBuilding a highly specialized camera, digital technology, such as new doors open is not possible with film technology.

In dentistry, an X-ray machine, a digital camera with a CCD sensor that is sensitive to photons, X-ray spectrum can be converted. Instead of impressing the image of X-ray film, developing the film and finally reviewing the image of small film, modern X-ray cameras automatically switch to an X-ray image on a computer screenScreen as the CCD processes the series of measurements photon. This not only saves time but also produces no waste in the form of exposed film and development chemicals. So with this frequently used, specialized camera, digital technology creates improvements in the practice of dentistry and protects the environment.

Another specialized camera, the benefits of digital technology is the telescope. Traditional cameras, mounted to telescopes collect points of light andPosition the film. This may be more sensitive than the human eye to faint points of light, but brighter points of light can also obscure the weaker ones of "washout" of the image. With the use of digital technology, the film camera is replaced by a digital camera with a CCD. The CCD can continue to receive and measure photons indefinitely. This means that the process is a continuous measurement of contrast with a simpler piece of exposure film. The computer can thenelectronically filter out brighter sources of light that enables the detection of very faint points of light in the sky and the study of celestial objects by detecting the shadow instead of light they give off. By comparing the light collected over time, digital technology also allows the camera from distant objects, allowing them to recognize this.

These are just two examples of how the cameras are influenced by digital technology. NewApplications and also the new science of such seemingly small advances in technologies that do not seem to bring all related. Remember the next time you check the digital camera.

Nikon and Canon - Photography Vs Technology

Professional photographers hired to covering demand photo shoots rely entirely on the right camera setup--job specific lenses, one or two dSLR bodies, and plenty of compact flash (CF) cards. For most photographers shooting medium format, Nikon and Canon are the only brands which ever make it into the studio. Both brands offer RAW file capabilities, large sensors, large hi-res LCD monitor, and the highest quality bodies and lenses, which are traits most important to pros. Still, each brand's products have their own distinctive features, advantages and disadvantages.

Nikon has dominated the film photography world since the 1950's and released the world's first digital single lens reflect professional camera, the 2.6 megapixel D1 in 1999. What made Nikon "the modern photographer's camera company" was its versatility and wide choice of autofocus (AF) Nikkor lenses, all of which are compatible with either their 35mm or FX film cameras. At the time of its 50th anniversary, Nikon listed over 60 AF lenses for sale ranging from wide angle lenses with focal lengths as short as 10mm, to telephoto lenses of up to 600mm, and a plethora of zoom lenses.

The Nikon dSLR body is very close to their 35mm bodies, which is a great comfort to long time photographers. While some options have changed, the overall anatomy is the same. Image size has increased almost 1000% since the D1, the D3X shoots 24.5mp images with max resolution of 6048 x 4032p while their Canon competitor, the Mark EOS-1Ds III, comes in at 21mp and max resolution of 5616 x 3744.

More choice of lenses and digital information will cost you, however, as Nikon bodies and lenses are generally more expensive than Canon and are heavier. The D3X weighs in at $8000 USD, excluding lenses, and 2-lbs without lens and battery. Nikon does, however, offer lightweight cost effective solutions such as the D70, 80, 90, and 3100 cameras which range from $1000-$3000 and include a standard zoom lens.

Canon has dominated the world of electronics since the 1960's and, like Nikon, is a Japanese-based company. They released their first pro dSLR on year after Nikon's debut and boasted a larger, better image. Consumers were familiar with the brand's point-and-shoot Powershot cameras--which made it on the scene before Nikon's Coolpix line--but professionals hesitated until September of 2001 when reviews boasted how much quieter, lighter, faster, and cheaper Canon's new EOS-D1 was compared to any equal quality Nikon dSLR. They also offered a 16-35mm f/2.8 L USM lens and other options which sought to offset the need for a large variety of lenses.

Since then, the EOS line, specifically the Mark II-III have been prime picks for Canon pro shooters. While Canon has released a Mark IV, this camera weighs in heavier than Nikons D3X at 2.6-lb and offers only 16 effective megapixels. Canon professional bodies are significantly cheaper. The 21mp 1Ds costs less $6000 and weighs less than 50-oz. Much of this is because Canon manufactures its sensors and a few other mechanisms in-house, unlike Nikon which mostly outsources its sensors to Sony.

Pro photographers will always consider the type of photography they are shooting. If carrying lots of lenses is impossible and mobility and cost are critical deciding factors, Canon has the versatility they need. Other photographers, however, love studying the science of getting the perfect shot with the best lens, especially when more time is allotted. Getting a new camera system is a huge investment which needs to be tempered with trials, research, and reading reviews from other pros.

How Digital Technology Has Changed Photography

Photography has always been a part of our lives. It has helped people capture precious memories - both the good and the bad. Through the years, photography equipment and techniques have evolved to become its own art form. Technology continues to evolve, constantly changing the landscape in which a professional photographer works his trade. Here is a short background on the topic:

What is Digital Technology?

It is usually defined as any system using parts that make use of binary or digital logic which is 1 or 0. If your tool or equipment has a micro controller or a processor inside of it, or if it uses storage and a software program that can perform even simple decision making, that means the equipment you are using benefits from digital technology.

What is Digital Photography?

In simple terms, it means using photography to capture images using digital technology. In the past, photographic film was the main ingredient for photography. But through progress and development, photography has taken the next level in its evolution by utilizing digital technology. With digital technology, you can print, store, display and do so much more with your pictures than you ever thought possible! You can use your equipment to store the images or, if you have a computer, you have the ability to transfer and store your photos onto your computer's hard drive.

With digital technology stepping in, it certainly has changed traditional photography in so many ways.

• With this technology, you won't need to purchase film anymore. It has the ability for you to review the shot taken and if you don't like how it was taken, you can always capture the image over again. This helps save money because there is no waste of a negative.

• The storage capacity for digital technology is enormous - you can easily store your pictures and keep your lovely memories for as long as you wish. Traditional photography, on the other hand, can not do this and you will have to pay more to have them printed.

• Digital photography allows you to print them as well, if you want. If you don't want to print your digital images, simply delete them or store them in your computer for future use.

• Digital technology allows you to review and edit your images almost instantly after the image is captured. Traditional photography requires many more stages before the image can be reviewed and edited, and each stage costs additional time and money.

• With digital technology, you can perform enhancements and add information on the picture such as added text or even the date. This process can usually be performed within the camera itself.

• ISO speed settings are easier to change. In fact, all film settings are much easier to adjust and set on a digital camera compared with a traditional film camera.

• It saves time and enables a faster turn-around on investment when shooting for a client, since the traditional ways of photography took more time to show the customers the image results.

• The cameras used lately are a bit smaller much easier to carry around. They are handy and not bulky.

• There are digital photo printers and computers that are available almost everywhere. These eliminate the cost of expensive processing equipment - dark rooms are now a thing of the past.

Those are just some of the changes digital technology has made in the photography industry. If you want to learn more, visit your local digital camera shop and ask some questions. Make sure you visit a store that was designed with professional photographers in mind - the salespeople there will be much more knowledgeable than your local clerk at a typical chain store.

Digital Photography As a Disruptive Technology and the Development of New Photographic Products

Introduction to Disruption

Disruptive technologies are innovations that unexpectedly create a new market and displace established market leading products and services. The music industry has been a great example of this: records were the first products that allowed consumers to own music and play it on-demand, but these were slowly replaced by cassette tapes and then compact discs. Each of these innovations had a profound effect on the market, on the one hand the quality of sound reproduction was better and with cassette tapes consumers were able to record music themselves. On the other hand they had to replace their old players with new technology and their previous music collection slowly became obsolete. Hardware such as the Sony Walkman became popular phenomena.

Compression formats such as MP3 were another disruption in this industry, making it possible to store large quantities of music electronically and more importantly to exchange these files easily. As a result of this disruptive innovation P2P networks like Napster developed for exchanging music, along with various software for copying, playing, cutting and modifying music. As with the previous innovations, this one had an immense impact on the hardware side as well, the best example being the Apple iPod which in a way inherited cult status from the Walkman.

Disruption in Photography

Digital Photography is another disruptive technology it has almost completely replaced film photography over the past decade. The decline in prices of digital photography equipment has made the technology accessible to the mass market. Digital Photography penetration exceeds 60% in many western countries.

One of the major changes heralded by the rise of digital photography has been the way people use their photos. With a 35mm film camera, that was the norm before digital, consumers would snap 12, 24 or 36 photos and then take the film to have developed without knowing the quality of the photos before seeing the finished product. Digital photography has had the effect that photographers take more photos, but print them less. This is due to the fact that they can screen the photos before having them printed.

New Markets and Products

Another major change digital photography has brought about is how photos are used. Developed photos were often stored in boxes or pasted in albums, sometimes framed and hung on walls. Digital photography bundled with advances in printing technology have given birth to a new market for customized photographic products. The self-made photo album has been replaced by the photo book, which is created using software and digital photos and is hard to distinguish from a regular hardcover book. A large variety of novelty photo products is available that ranges from mouse pads to coffee cups.

A product category that has recently begun to emerge as a result of the proliferation of digital photography is that of wall art or wall décor. Increasingly, art prints, framed photos and paintings are being replaced by photographic wall art. Many amateur and professional photographers are using wall art as an outlet for their creative energy. They go to great lengths to make photographs and want to display them somewhere. One of the first types was the poster, as it is easy and inexpensive to produce and dispatch. But a premium segment has developed for canvas and other photographic wall panels. Printing technology has evolved to be able to print not only on paper and cardboard but directly onto canvas, acrylic, metal and other materials. This has made a new class of photographic wall panels for interior decoration. Photographic wall panels have become a tool for design due to their unique properties. Acrylic panels, which are essentially plastic panels onto which an image is directly printed, are particularly attractive because they can be combined with innovative lighting to create unique effects.

Conclusion

Digital printing has profoundly affected not only the photography industry but it has also paved the way for new technologies, products and markets. It has influenced the way people take photos and what they do with them afterward. It has made established industries and products obsolete (film development, 35mm products), while creating new products and industries (web-to-print, acrylic panel, canvas print, photo books etc.). Digital printing is a prime example of the power of disruptive technologies.

Rudiger is a photojournalist and blogger who has a passion for visual arts and photography. He writes about news in photography as well as digital printing. He follows companies in the photography and digital printing space and is particularly inerested in the developmnent of new product categores such as canvas prints and photographic wall panels. He uses photographic prints to display his own digital photos, which focus on landscapes and cityscapes.

Camera Digital Technology - Sensors, Storage Space And Snapshot Sharpness

Camera digital technology: do you have to understand it to utilize it? Probably not, especially if you're using a consumer digital camera - a point-and-shoot - and you just want to get that holiday trip recorded for posterity...

On the other hand, it is quite useful to have a good grip on camera digital technology to get the best out of that little technological marvel!

For starters, it makes sense to know that the number of pictures you can take on your camera depends on the file format you select, and on your camera's storage capacity.

Camera digital technology generally works with two main formats, the JPG and the RAW file. The latter is for storing as much as possible original data per picture, to be adjusted later on a PC. The RAW format is of particular interest to professionals. RAW pictures often need nearly 10 times as much storage space as JPG files, so a casual photographer will generally choose to use JPG.

However, your camera might give you the option of selecting high quality JPG's or standard quality JPG's - the latter using less space, and mostly giving quite satisfactory results.

The camera will store the picture files on a card. A 256MB card can sometimes store more than 80 images of standard JPG size. If you're willing to spend more, new camera digital technology allows you to buy cards with 10 times more storage capacity.

Another aspect of camera digital technology which is useful to know about, is the way the images are captured. In stead of the film of well, film cameras, digital cameras have a silicon sensor with light-sensitive photosites (pixels) which capture the light information.

These sensors are often less precise than film when it comes to rendering detail in shadows and highlights. Camera digital technology therefore dictates that you should be careful not to "blow" your highlights. If they are not captured in the first place, you can't make any adjustments afterwards in your software processing.

To ensure you capture as much shadow and highlight detail as possible, and in a balanced way, camera digital technology offers you the use of a histogram. This handy tool is a little graph which indicates how the levels of brightness are distributed in an image. Many cameras show a histogram in real time, while you compose your image, giving you the opportunity to make exposure adjustments.

While digital camera lenses are essentially "old technology", it is useful to know that you can get excellent quality pictures from fairly inexpensive consumer cameras. This has once again to do with the sensor used in camera digital technology.

As the sensor in these point-and-shoots have a much smaller surface area than the 35mm film of a film camera, the former can get a much sharper and detailed image than a film camera with the same lens, due to the smaller focal area.

Camera digital technology has the major advantage of offering you stacks of opportunity to experiment with taking first-rate pictures, because you don't have to be concerned with the expenses relating to camera film.

So go out there and put the new camera digital technology to use!
