First Computer Invented:

most people when they think of first computer invented they think Bill Gates. However, this is not true, because the computer was invented long ago about Bill Gates. Bill Gates only revolutionized the computer, buy creating a compact and useful form of the computer and making it available to everyone on the job.

There are many people who say that the first "computer" was the abacus, invented in Asia about 5000 years ago. However, it is not.

The first of the "modern" computers found during the Second World War, in 1941, a German engineer named Konrad Zuse. His name was the Z3 and was used to help design German airplanes and missiles & # 39; s. Then in 1943, the Allied forces developed a computer called Colossus. It helped decode German messages.

The Mark I, designed by Howard H. Aiken, an engineer working with Harvard and IBM. The Mark I was positively huge, taking half of a football field. It was useful though and helped to create ballistic charts for the US Navy during the war.

Shortly thereafter, was developed by the Electronic Numerical Integrator and Computer (ENIAC), John Presper Eckert and John W. Mauchly, working with the Government and the University of Pennsylvania. ENIAC was about 1000 times faster than the Mark I, but not wiser.

The use of transistors, went computers can store memory and even run programs. Shortly after finding the computer language that people can change the programs running on your computer. Finally computer research brought us smaller, useful computers, and eventually to have a variety of computers today.

First Laptops Invented:

Although it is a little hard to determine what the first portable or it was a laptop, and when it was invented, but they say they need more than a laptop fame. There was even signs of laptops dating back to 1979, it has been designed by a British, William Moggridge, for use by NASA in 1980 & # 39; s. It was one fifth the weight of the model is the same power and a 340k byte bubble memory lap-top computer for cast magnesium and folding electroluminescent graphics display.

Since then, notebook PCs & # 39; and released in 1981 lay clam to be the first. It was the Epson HX-20, a battery powered portable computer, a 4-line 20-character LCD display and a built-in printer that started the new widespread desire for these laptop computers.

In January 1982, Microsoft & # 39; and Kazuhiko Nishi and Bill Gates want to start the design of a portable computer based on negotiations of a new liquid crystal display or LCD screen. LCD technology in 1982? Yeah, that & # 39; s right! Believe it or did not have the technology to LCD televisions and monitors, it & # 39; I have seen only recently over 22 years ago. But what are the & # 39; s another story.

First PDAs Invented:

First PDA is a personal digital assistants in case you did not already. In 1993, Apple Computer Inc. released the very first PDA (Personal Digital Assistant) "The Newton®". The next three years, PDA sales declined and almost off the charts. Then in March 1996, Palm (TM), Inc. delivered the industry & # 39; s first truly compelling handheld computer, Palm Pilot. Now, most PDA companies and products even bother mentioning.

First TV spot:

the first signs of full date back to 1862 when Abbe Giovanna Caselli invents the "pantelegraph" and become the first, who shall transmit a still image over wires. In 1900, the World & # 39; s Fair in Paris, the 1st International Congress of Electricity was held, where Russian, Constantin Persky made the first known use of the "television". In 1930 Charles Jenkins broadcasts the first TV commercial. The BBC begins regular TV shows.

Then, over the years the inventions came one after another. In 1950, the FCC approved the first color television standard which is replaced by another in 1953 Vladimir Zworykin developed a better camera tube – the vidicon. In 1956 Robert Adler invents the first practical remote control. In 1973, first placed a huge projection TVs. Then the Sonys release of the first home video recorder 1976.By the time 1996 came around there was a billion TV sets worldwide.

First DVD / Player Invented:

We can only assume the transition over cd & # 39; s and CD players through DVDs and DVD players was not that hard. The technology is already there they are. So the dvd player was surely invented before or after the DVD invented. DVDs are the work of many companies and many people. The DVD evolved from CD and related technologies. Companies such as Sony, Philips, Toshiba, Matsushita, Time Warner, and others announced the new "high density" dvd in September 1995

What is the best buy old printer?

As we know, the old man missing half of life on Earth. You do not have to do ordinary daily activities. However, they do not need to have a taste of the technology? I sure agree with this rhetorical question. An elderly man & # 39; and in general daily schedule: wake up, read the news paper; and then goes on the field, then engaged in the business partnering meetings. A person whose age 60-100 already an old man.

A pre kindergarten teacher asked her students once a little child. "What old grandfathers?" then they all responded, "It sits in a chair all day and smoke a pipe." This is a very funny assumptions. Some older people remains strong and ambitious in the short-lived future.

The Pixma iP100 Canon printer is a printer, I highly recommend you to use the old people. This is a digital photo printer. This printer is capable of aging, because you might organize your daily appointments. This can be an appointment with a doctor, or a businessman. An old elderly person is capable of this type of printer to produce a program chit to be his / her daily reminder to do your daily activities. The Canon printer is made of quality, maximum resolution and high-speed black and color printing speed. This feature allows you to create documents printed in black at the moment. In fact, there is a wireless network adapter that allows one to gather information about the radio and not computer cables.

Another printer is suitable for this type of group is a portable laptop printer. This is an effective mobility, and also the duration of the long tooth and blue pattern. This allows the user to receive the processed data to the printer. He also original ink components, which are mainly shipped directly from Africa. As if that is not all, the printer is a thermal in nature and because of the intense heat processing files.

a very old man who keeps himself busy. He / she must have a portable printer, which is very comfortable in her daily activities.

Trends Of toner and ink cartridges

Two reports recently released by Lyra Research, the digital imaging authority, providing in-depth information analysis and forecast market data in the field of digital imaging devices. The results, which are published in these reports Lyra utilize the findings, which were originally released in the first half of 2011 Hard Copy Supplies Advisory Service forecast 360. The two reports forecast the world each toner between 2008-2015 and 2008-2015 Forecast cartridge on the desktop.

every toner World Forecast, 2008-2015 explains that the trough occurred in the laser printer market. Sales will continue to grow in future markets and get back to the year 2011, this increase in hardware sales caused significant recovery in demand for those who need to get to the toner. The change is also expected to expand to color output devices and cartridges consignment can handle print jobs that are high-volume demands. The total is expected to increase to EUR 379 million in 2010, up to 445 million in 2015, the highest growth in Asia and Latin America.

every desktop ink Forecast World, 2008-2015 takes a look at the last two years, and that was the market for ink cartridges impact of the recession. This is partly because the WiFi networks, different printing habits for computer users, and use screen-based devices. Deliveries are expected to increase, especially for users gravitate away from the use tricolor cartridges for printers and select the better quality, which the individual color ink cartridges. The prices of the cartridges is expected to drop, but revenues will rise to an increase in sales from # 29 billion in 2010, up $ 33 billion in 2015, the greatest growth will be in sales similar to the laser toner forecasts, the highest growth in Latin America and Asia lesser growth occurring in Europe and the United States.

The recession, the impact of the ink cartridge market, as it did in many other markets. Larry Jamieson, a senior analyst at Lyra Research, also noted that other changes, such as the "forces arising from changes in printer usage patterns, such as the MPS engagements, WiFi networks, and the use of mobile devices and screen-based applications" contribute aa market changes and forecasts. This does not mean that the market is completely dead, and reports indicate that expectations of imaging devices in lean toward modest but steady growth fueled by a general shift towards consumer color output devices.

What equipment is needed to shoot Panoramas Virtual Tours?

The camera – to create high-quality panoramas you need a high quality DSLR camera with interchangeable lens and possibly bracketing. You have interchangeable lenses, as if with a fisheye or wide-angle lens is almost essential for effective and detailed view without the half-million individual images. Uing mean wide-angle or fish-eye lens, you might want to invest in a very high megapixel camera. This is because of the wide angle lens bends light more images to fit the same number of pixels. Low-megapixel camera is not high enough resolution to be able to handle the edge of the circle section of the fisheye image. I would not use a fish-eye lens anything less than a 16 megapixel camera with a wide angle lens, less than a 10 megapixel camera.

If your budget allows, spring is definitely a camera that bracket, it allows you to High Dynamic Range (or HDR) images and is a fantastic tool to produce images exposed around the virtual tours. High-megapixels and the bracket features to find all professional DSLR cameras. I highly recommend the entry-level Canon 60D, you can pick one up for about £ 600, and the amazing pictures they produce. If you are willing to spend a bit on the Canon EOS 5D Mark II is still my go to choice for the go shooting every day during the week, organs are available for £ 2000

lens – opinions differ on the type of lens for best results. Some virtual tour photographers wide angle lens, others prefer a full fisheye. Both merits: Wide angle lenses create less pixel distortion around the edges of images and reduces the risk of pixilation within a panorama, which can seriously damage the quality of the virtual tour. However, they require images to create a panorama much more. This massively lengthen the time before and after the production process and increase the chance that one or two according to the pictures may not stitch. Full fisheye lenses on the other hand only need a couple of pictures to create a complete panorama of the compromise is that the same picture points to a much larger photo, so the pictures are of inferior quality. I realized that if a fish eye lens for photographs that focus as well and pay attention to the images, then there is nothing that a fish-eye is not better, simpler and less time than a wide angle. I highly recommend the Sigma 8mm autofocus, you can pick up for around £ 800th

The Tripod – Tripod is one of those things that amateur photographers almost always feel the need to be bad figure that ahead of time to get it right. You have to remember that the panorama scene node MUST around the first concern is to make sure that the camera does not move even slightly the position of the node during shooting. Your enemy is the wind, accidentally knocking the stand and to re-position the tripod head, they all avoided investing in some good strong unit. You can pick up a Manfrotto tripod legs and £ 500 ball head tripod ball head as particularly useful, you can easily transfer Panohead level of a full (ish) 360 degrees, even in difficult situations, or uneven terrain. They recently filmed a panoramic photograph of a four-story statue of a beam nine feet in the air. The only way I was able to stand on two feet was stable resting on the wooden slats, and the last of the light, the stand has grown to almost double like an old man; Without the ball head tripod buy a panorama would have been impossible.

The Panohead – The Panohead specialist equipment that is used to find the node (or parallax) points. The nodal point is very important when taking panoramic images, since it allows the pictures to be taken exactly the same perspective. If even a few millimeters, then the object slightly closer or further away is the perspective shifts to one another that when it comes to stitch them together, it is a big problem. There are ways to address this without investing in a tripod and panohead, as Philopod lead change of the method is very popular However, if you want to panoramas can be sure that according to stitch together all the time, a good stand and panohead essential. Panoheads many shapes and sizes, budget-friendly Panosaurous a terrible motorcycle Auto-rotate VR head. After experimenting with several of these, I found that very little that can be achieved with a fully robotic Super Dooper T-800-vista baby Astala Panoheads not be able to do it in a narrow midrange modular set. Pick up your ninja node is an award-winning yet refreshingly affordable £ 200

a good DSLR camera, the right lens, a sturdy tripod and a smooth panohead you It is the way to create beautiful panoramic photos using a virtual tour.

American manufacturers of Gun Safes and Gun safes Amseco closer look and Cannon Gun Safes

When shopping for manufacturers of safes and gun cabinets, you can & # 39; sa good practice to stick with manufacturers who respond to the higher standards to remain competitive in the market. In the US, it often means that quality at the local level. American-made products tend to adhere to a higher standard to be viable. Here is an alphabetical list of some US manufacturers gun safes, and what to expect.

American Security Safes Also known as "Amseco" the Amseco gun safes enjoyed among solid reputation for gun owners for decades, the company began in 1948 are manufactured in California, arguably the strictest state in the union when it comes to regulatory standards for safe production (eg, "CA DOJ-approved" symbol gun safes), Amseco knows the trade. They made a name for themselves by being the first manufacturer to receive UL safe & # 39; and TL-15 and TL-30 classification system, anti-theft devices they include. They were the first to create a round door vaults – an innovative design that deters break-ins. American Security Safes found this door is the high price was enough to send them to the drawing board to create a cost-effective, although certainly, square and rectangular door design. They are driven by quality to price.

Cannon Safes Cannon has a safe manufacturing business for more than four decades. Their task was to provide affordable security options and supports products is one of the best warranties on the market. The Cannon gun safe behind a lifetime warranty. Canon offers a lifetime replacement guarantee and pay a tech to open the safe after attempted burglary safes, fire or other disaster. They also have to pay for on-site repair or shipping charges to send secure and factory for either of these disastrous events. The reason being, Cannon gun safes long-term investment in the company & # 39; s eyes. As for the fire rating UL RSC-security safes are certified against burglary and Intertek-ETL certified for 30 minutes, 90 minutes in some models of Safari models.

Liberty Liberty is a Utah-based company, new industry standards in the industry (1988), but they're used to the best business practices to make a significant name for themselves. The safes have the UL, Underwriter & # 39; . Lab and quickly reached the top position in the full-size home safes in the US, good work ethics and procurement National Security Safe Co. & # 39; 97. It is also designed door technology are "HiSecurity composite" doors, which FireBoard layered, hardened steel plate and steel added fire protection and safety standards. These shops also operates an innovative shelving system is a patented system and introduced the Liberty that was adjustable.

Spotlight: American Security Safes

As previously reported, among Amseco gun safes with some of the best prepared in the history of show. They developed a complex structure that combines a hard disk with concrete, which then was still a winner to eliminate fire and theft. Due to their innovative design and focus on building anti-theft, during UL testing Amseco gun safes worthy of the anti-theft rating TL-15 and TL-30, which remains one of the best ratings in the retail market safely. The rating means that the question is resistant safes concerted attack invaders device 15 or 30 minutes, and the U.S. Department of Justice statistics show that in most safes against burglary average of about 7 minutes. In other words, these safes buys the necessary time to protect your investments.

American Security Safes has started since Glenn Hall in about 1948th In the beginning, only Glenn started the welding machine and lathe and wanted to have a secure safe that can withstand a break-in attempts. Amseco gun safes have formed keeping with this focus in mind and the decades have made substantial progress in engineering to keep ahead of the game.

Such a plan was the porthole. They are very effective deterrent against theft, but essentially the high cost of production. However, this function was held Amseco design innovation ahead of the competition and the design is a standard against which others are measured.

Because of the increased demand for safes, he wanted to make the American Security Safes cheaper than the common man. The door has been redesigned to accommodate a square, while maintaining a high level of safety for consumers. This required changes to the other store operating to standard high security, it took all of 1960 & # 39; s. In the 90 & # 39; s, Amseco was the first company (in the US) to receive the UL & # 39; s invading rating (see above), which is ahead of the competition. In fact, very few manufacturers bother this high level of security while Amseco & # 39; s concern for burglary before most manufacturers today, with a few exceptions.

American Security Safes has hit the production of higher quality by itself. Another example of how to put the electronic lock on the usual so-called "Method 106 Mil-0202", which is a military-grade standards to check the reliability electronics.

as the date Amseco gun safes for the best welding construction practices, and the company, swirling around Safes 600k / year, Fontana, CA. When you buy Amseco gun safes, you & # 39; ll be treated to affordable quality and scratch-resistant interior, gun racks, shelves and plenty of space. They also offer fantastic "No Cost" guarantee – no shipping costs, repair, replacement in case of an attempted burglary or fire.

Spotlight: Cannon Gun Safes

Cannon gun safes to Cannon Safes, whose motto. "Nothing Protects like a Cannon" They have been in business for more than four decades, and has been making innovations in the game plan. They specialize in design break-throughs, and back it all up with a strong "life" guarantee. As Amseco that has a lifetime warranty, which includes shipping, parts and labor or replacement during a theft attempt safe, flood or fire damage.

Cannon safes are five main lines: Traditional, Cannon, Patriot, American Eagle and Safari. They also offer the home and office safes, which are more in the line of personal-size safe, as opposed to the larger gun cabinet style dryers. Cannon also guaranteed a series wall.

Starting with the traditional series, and there are a handful of safes in a row, beautiful to look at. Elegance can not be what you think about when you consider safe, but there you have it. This class offers a safe rounded edges on the outside, which is supposedly greater durability. In contrast to the interior is great, oak shelves, upholstered surfaces, and even interior lighting options and a dehumidifier option as well. The ETL certification fire-rated capacity of 1200 F for 90 minutes. The handle is a nice 5-spoke, it protects better than expected required UL Type 1 rated electronic lock (industrial grade). The security, secure multi-relockers theft attempt, and a screw-down option as well.

Safari series which is shared by the more economical "Serengeti" and the top-of-the-spectrum "Dangerous Game" series, the latest Cannon design of weapons available. A Dangerous Game Cannon gun safe is multiple choice. Boasting beautiful pin striping and painted bust of buffalo, Dangerous Game Series is essentially a conventional (top row), but Safari design to it. The edges are rounded than traditional suede-lined interior and added shelving for small luxuries.

Other features Cannon gun safes, which are nice touches (not available on all models): the internal LED lighting, which comes when the door is open (like a refrigerator) and switches off when you close the door on a great touch! So the dehumidifier rod that you can choose, but you can usually buy them after market. Of course, you can only use a desiccant pack, but the cable slot is a nice touch that the mold off. The Cannon "Tru-Rack" system is one of the only mining opportunities in the market that allows you to rack as many weapons as you can & # 39; advertised, so the 36-gun safes can store 36 long guns.

The Serengeti fire resistant for 60 minutes at 1200 F ETL, while the dangerous game is 90 minutes. The Serengeti & # 39; door and a composite 1.5 ", a dangerous game 2:25" composite, and two double steel 10 or 12-gauge steel fire protection. Another difference is the capacity in which the Serengeti is less dangerous play, goes up to a 36-gun capacity.

No matter what product or buy the American Security Safes Cannon Gun Safes, it & # 39; be sure that your investment will be protected by high design, reputation, and ensures that you & # 39 should ensure, again, that is a wise decision.

A Brief History of laptops

The idea laptop was already in the late 1960 Dynabook, but this Tablet PC for mainly children.

There was no real commercial incentive to develop a truly portable computer, (and thought to be practical in all cases), so it was not until much later, new developments in transistors and processors, that the laptop They considered as something more than just a child's game.

it was the early '80s, the first truly portable computer was developed, the Osborne 1 was not analyzed, (I had plugged in), but at least the data and the computer can be shipped.

a few years later, in 1982, Compaq computers were released.

is widely accepted that Compaq was not much better than the Osborn 1, but because of the new popular MS-DOS operating system (used during most of IBM computers), it turned out, was an immediate success .

last year Epson announced the first truly portable computer battery nickel. Epson was more like an advanced calculator only 80 characters will be displayed at a time.

also introduced the Compass 1101 will be credited, around the same time giving us the now known design of the laptop computer screen folded shut over the keyboard.

In 1984, Gavilan SC and Sharp PC-500 entered

into the market, the Gavilan was the first that the concept of the laptop (and basic pointing device).

1984 also saw the arrival of the Kyocera Kyotronic 85, it was small and offered a variety of applications such as a word processor, a spreadsheet or a modem, and it's very popular indeed.

By the end of the 1980s, many laptop manufacturers have developed fairly similar machines. Everything that from the size of an A4 page is an A3. Most of the NEC Ultralite, the Cambridge Z88 and the IBM PC Convertible. The Compaq LTE introduced a portable hard drive (up to the date of the operating system stored in ROM and floppy disks were used).

set out in the early 1990s, the look and feel of the Apple laptop was by computers (built-in trackball, keyboard and palm rest). Not to be outdone the IBM Thinkpad 700C introduced the TrackPoint one year later.

Since the mid-90's only improved technology for portable computers. Longer battery life and a huge hard drives, now that the laptop a serious challenger to the table.

History of the camera

Early cameras were the 16th and 17th century, the ability to project images on paper or glass but the study of recording, processing and printing the images took many more years. Until the 17th century, scientists thought that light consisted essentially of & # 39; White & # 39; to be detected by the human eye. famous physicist Isaac Newton conducted the research discovered that the light is actually a spectrum of colors. While great contribution to the study of optics (that is the core of camera advances) the discovery, Newton did not actually anything to do with camera development per se.

The early camera that was the first time the phenomenon has become a little more like a hidden camera and can be traced back to 1558. It was called the Camera Obscura. The Camera Obscura was seen as a drawing tool for a clearer and realistic portrayal of objects. This was the beginning of the 19th century to the present invention named the Camera Lucida led by Cambridge scientist William Hyde Wollaston, that it was an optical device that can help the artist to see a distant scene or person or object on the surface of a paper that he had been using to call. In other words, you get to see the artist superimposed image of a subject on paper and this image could be effectively used in an attempt to draw, trace or paint it. All of the pictures in the Camera Lucida Camera Obscura and was granted a temporary, which can not be permanently attached to the paper for later use.

However, the study is still in the 1800 & # 39; and how to actually capture the image onto material. It was during this time, around 1822 that French researcher Joseph Nicéphore Niépce, created the first photograph using paper that is coated with a material. The picture does not stay permanently on the paper and would disappear after a short period of time. Even so, despite the short-lived nature of the picture, the concept of photography was born in this experiment and paved the way for the further study and development in this area.

shooting to keep them longer and permanently became the next big quest for researchers. Another Frenchman Louis-Jacques-Mandé Daguerre partnered Nicéphore Niépce in 1829 to develop the unit's process of creating permanent photographs. Joseph Niépce died in 1833 but Daguerre continued the work and succeeded in 1837 after many years of experimentation. The process of capturing photographs, which does not disappear, introduced by Daguerre came to be known as the & # 39; Daguerreotype & # 39;.

The word & # 39; photography & # 39; Sir John FW Herschel scientist coined in 1839, and he actually comes from two Greek words & # 39; Photos & # 39; which means light and & # 39; graphein & # 39; ie tie.

a little bit more advanced version of the daguerreotype called calotype process, which can be more than one copy of the negative and positive method became available very soon after. In fact, during the 1840s it & # 39; and that the use of photographs advertisements first started and cameras made their mark on the power of visual communication. It was not much later, in the 1850 & # 39; and that photographers first started experimenting with underwater photography sea.

Until 1850, the process of shooting was cumbersome requiring up to half an hour illumination. The discovery in 1851 by Frederick Scott Archer was a blessing since the new method is called Collodion process called only 2-3 seconds to light exposure to capture the image.

Before 1871 photographers went through a development process, which was to coat the plates wet chemical each time, and process the image immediately. The invention of the gelatin dry plate silver bromide process by Richard Leach Maddox, negatives can not be developed immediately. This is an important finding because until then the captured image had to be processed immediately.

Kodak created in 1888, George Eastman was a pioneer of sorts today's cameras and photography to the masses. George Eastman and the scientists who worked with Kodak developed the photographic film in 1889 and made it available in rolls for mass use by consumers. An important milestone in the development of entertainment and communication history was transparent roll film of Eastman. This development led to another key invention – the motion picture camera by Thomas Edison & # 39; s in 1891.

-> Modern Times

During the 20th century, the pace of technological development in cameras and photography continued at an accelerated pace, like many other key technology developments. While several key inventions like car, telephone and the gramophone record happened in the later half of the 19th century, this is the last 100 years that saw many areas of major development work in communications technology and other areas – television, airplanes PCs, digital technology, digital cameras, cell phones, fax machines and the Internet, to name just a few.

In the case of the camera, the developments simplified the whole process of photography, accessible in one place and at affordable prices and the camera industry of our time residents has a mass phenomenon. The first mass use camera became available at the turn of the 20th century and can be traced back to the year 1900. Hundreds of camera models available today in both amateur and professional, and the camera is an important part of every family & # 39; s repertoire should gadgets.

-> 20th century chronology of the history of the camera:

1913: 35 mm still camera captured

1927: A light bulb in the General Electric Co. (The concept of camera flash It existed long before, but based on the use of flash powder invented by German researchers)

1935- 1941: Kodak starts marketing Kodachrome film and then start Kodacolor negative film. Canon released the Hansa Canon in 1936, the first 35mm camera shutter.

1948: The concept of the Polaroid camera on the market. American scientist Edwin Land developed the process for instant photos. Later Polaroid Corporation developed the & # 39; instant color & # 39; Around 1963 film

1957: Jacques Yves Cousteau French invented the first waterproof 35mm underwater photography named the Calypso Phot. Developed by the actual camera Belgian airplane technical designer Jean de Wouters based on the blueprint and suggestions given to him Cousteau.

1972: The electronic camera that does not require film was created and patented by Texas Instruments. However, this is not the same as a digital camera, you do not need digital film cameras as well. The launch of the digital camera is still many years away.

1975: Kodak & # 39; s digital imaging experiments started around the mid-seventies, but it's another 20 years before a digital camera launched in the domestic consumer market.

1978 – 1980: Asian players like Konica and Sony begin to make a mark. A & # 39; point and shoot & # 39; Launched by Konica auto focus camera while Sony starts talking about the camcorder and demonstrates a prototype.

1981: Sony introduces a commercially available electronic camera. Similar to the 1972 invention of Texas Instruments, Sony electronic camera came with a mini disc on which images captured and stored. The recorded images could be later printed or viewed on a monitor with a reader device.

1985: Digital processing technology makes entry. Pixar introduced by the digital imaging and processing.

1986: The camera industry is more consumer focused and taps the fun and travel connotations behind camera use, the launch of the concept of disposable, single-use cameras. Fuji approve of this idea.

Also in 1986 – 1987, Kodak started tremendous strides in digital development. Digital tools of the photographic image is divided into small units of dots or squares known as pixels. Pixels are programmable units of an image that can be processed by a computer. All shots million pixels. The use of pixels in digital technology allows you to store a large amount of pixels delivers high-resolution print quality.

1990: Kodak Photo CD market & # 39; s. It is a system to store your photos on CD and then viewing them on your computer. With this development the user-friendly approach of the camera industry began to concrete form.

1991: Kodak digital camera market in a targeted professionals and journalists. Kodak credited with the invention of a pixel based camera technology known as digital cameras. Digital cameras do not use film similar legal predecessor electronic cameras but the storage method is entirely different and the final photograph is much higher resolution. The digital images are recorded and stored in digital form. This digital data can be transferred to a computer and print-ready. Kodak and Canon are well known digital camera manufacturers and there are also several other key brands as well.

1994: Apple Quick Take camera, digital camera launched for home use. This is followed by the launch of a clutch home use digital cameras, Casio, Kodak and others in quick succession during 1995 – & # 39; 96.

-> The digital era:

The development of digital camera technology is considered to be related to the development and video technology. The principles of transmission and recording of audio-visual images using digital electrical impulses finds the camera as well.


to 1990 & # 39; and a closed technology developments continue, the focus is now shifting to the field of digital imaging, which is where the future. Use-friendly features like software that can download digital images directly from the camera to store and share home computers on the Internet the new norm in the market.

The camera, the computer, the software industry and the worldwide web today irrevocably together to empower users to experience the benefits of using the camera to its full potential. The innovation that sparked many an invention in the camera industry found its way in the digital world as well and continued to a variety of digital camera manufacturers. the Kodak and Microsoft partnership ensured in 2001 that digital camera manufacturers could use the power of Picture Transfer Protocol (PTP) standard Windows. The digital photo experience is a key visual driver in the Internet age. Many Kodak EasyShare digital camera models are compatible with Windows XP capabilities. The Kodak EasyShare software enables users to your digital camera pictures directly from the camera to the computer, and then print the pictures or even email them.

Manufacturers of related industry like the printing industry have adapted their products to sync with the images created by digital cameras. Mobile phone manufacturers connected to the digital camera manufacturers to new age camera phones in recent years. These camera phone pictures and share images on the cell phone.

Among the 21st century digital developments in the advanced product line of digital cameras manufacturers and these are sure to occupy an important place in the history of the next camera development. For example, the Kodak Professional DCS Pro SLR / c is a high-end digital camera and a Kodak DCS Pro SLR website draws the most representative models of rich digital cameras on the market. It has an image sensor that can handle 13.89 million pixels and this makes it the highest resolution digital camera available. High resolution determines the sharpness or detail photos. This is just a glimpse of the capabilities that digital technology places the user & # 39; s hands. Digital camera sales figures show that in 2003, the two key players Kodak and Canon recorded impressive growth.

-> What the future holds for camera users?

digital cameras provided by the service can be pretty amazing for the average user, and very exciting for most pros. Four key ongoing camera developments that are likely to further improve the process of photography:

1. High resolution, even the simplest, low cost camera models

2. In addition to use in any type of lighting

3. Compatibility with a whole range of software, hardware and image types

4. Rich colors and tone

While the higher-end digital evolution continues, the prices of simple camera crashed to the extent that even kids and teens proud owners of simple cameras. The camera and photography interest starts young and this creates a truly large audience base for the camera.

Throughout history, it is clear that the ambition of researchers and developers has been to the camera in a wide range of society. Without camera technology and photography, the other key developments of cinema and TV would have to be postponed, and what a boring place the world would not have TV and movies !!

My Canon digital camera says "Memory Card Error" – Help!

Many people are asking about the camera's memory card displays them in an error message. If this kind of problem, do not worry, because this problem is often asked among photographers. Do not forget that if this thing happens, just do not format the card, and it should not take more pictures. You should be aware that the photos still intact on the memory card, it takes multiple images to rename the old ones.

So what do you do if you really need that picture off although the card is corrupt? Here are some things to solve this problem:

First of all, check the camera manufacturer's website and check out the latest SDHC cards will not work with the older camera. It is therefore probably need to change the memory card standard SD card only (usually those 2GB or less).

Second, you can format the card to correct problems with the camera, but please remember to format the card in the camera can also delete all the photos on the card.

Third, make sure you do not accidentally insert the small side slider locking the SD card in the "closed" position down. You need to slide up toward the direction of the connectors correct "tripped" position.

There are many other troubleshooting items to check the problem of "memory card locked" or "media failure". The important thing to remember is not the format, if you need the pictures and you will get a message that says "no image" or "no data" if the Canon properly formatted.
