21 Sep 08 Nikon’s New D2Hs Professional Digital SLR Camera Offers Enhanced Performance, Image Quality and Features
MELVILLE, NY, FEBRUARY 16, 2005 - Nikon (www.nikondigitalusa.com), the world leader in photography, today introduced the new D2Hs™ professional digital SLR camera that incorporates several new enhancements and features. Designed for photojournalists and sports/action photographers, D2Hs integrates the best technologies from its predecessors with an array of exclusive new innovations that deliver the speed, response and handling required for action photography.
The range of new features and enhancements in the D2Hs are based on extensive research and feedback from professional photographers around the world. An all-new image processing engine in the camera produces images with higher quality, finer gradations and lower noise, while a newly refined exposure metering system improves on Nikon’s hallmark 3D Color Matrix technology. The D2Hs Auto White Balance and auto focusing systems have been fine tuned to deliver precise, accurate results and an enhanced buffer now offers continuous shooting at 8 frames per second for up to 50 consecutive shots (JPEG, FINE).
“During the development of Nikon’s recently announced D2X professional digital SLR camera, the company created several new technologies and innovations that delivered breakthrough performance in that camera. These new innovations have been integrated into the D2Hs to offer photojournalists and sports photographers a camera at par with Nikon’s flagship D2X camera, with comparable performance, features and seamless workflow,” said Steve Heiner, general manager for Digital SLR and Professional Products at Nikon. “Photographers will appreciate the seamless design, transition and workflow between the D2X and the new D2Hs, allowing them to quickly switch between the two best-of-breed camera bodies, as dictated by the situation they need to photograph.”
In addition to Nikon’s exclusive 4.1 megapixel DX format JFET image sensor LBCAST (Lateral Buried Charge Accumulator and Sensing Transistor array), the D2Hs features the following new technologies and enhancements:
- Advanced new image processing engine produces high quality images
The new image processing engine adopts advances from the D2X to further improve overall image quality in the D2Hs, producing images with finer gradations, lower noise and consistent, smooth transitions.
- High-speed continuous shooting at 8 fps for up to 50 consecutive shots
The speed achieved by the LBCAST sensor and the camera’s image processing allows the D2Hs to shoot continuously at 8 frames per second for up to 50 consecutive JPEG or 40 RAW (NEF) shots.
- 3D-Color Matrix Metering II
Refinements to Nikon’s hallmark 3D Color Matrix exposure metering system in the D2Hs result in optimal exposure calculations from the data supplied by the 1,005-pixel RGB Exposure/Color Matrix Metering Sensor, even when shooting under challenging conditions.
- Precise white balance
The D2Hs uses refined Auto White Balance (AWB) and Auto Tone Control (ATC) systems to deliver precise white balance settings when shooting in tricky or mixed lighting situations.
- Faster, higher precision 11-area AF system
Refinements to the camera’s AF and lens drive algorithms further improve focus precision, subject acquisition, and subject tracking. The high precision and speed of the D2Hs’ AF system also contributes to achieving high-speed continuous shooting.
- High-speed wireless data transfer and camera control
The D2Hs is compatible with the Wireless Transmitter WT-1/1A as well as the new Wireless Transmitter WT-2/2A, which supports both IEEE 802.11g (for faster transfer speeds) as well as IEEE 802.11b networks. The WT-2/2A also strengthens wireless security options and supports a wider variety of network protocols, including the new PTP/IP protocol that realizes wireless Capture Control from a computer running Nikon Capture 4 (Ver. 4.2.1 or later).
- sYCC color space support
Added support for sYCC color space produces JPEG files that can fully exploit the output capabilities of the latest color printers and use a gamut wider than sRGB to achieve optimum print quality.
- GPS connectivity expands applications
The latitude, longitude, altitude and UTC (Coordinated Universal Time) at which a shot is taken can be recorded from a GPS unit to the image’s metadata. GPS units that comply with the NMEA 0183 (ver.2.01) interface standard can be connected using the optional GPS cable (MC-35).
- High-resolution 2.5″ LCD
A new large 2.5-inch LCD monitor with a higher resolution of 232,000 pixels adds an all-digital interface for clear, flicker-free display of images and information. Displays include preview images at up to 15x magnification, an improved histogram display, and new selectable RGB histogram displays, making exposure confirmation quick, easy and accurate for each of the red, green and blue color channels. Other useful displays include the World Time function and the chronological Recent Settings list.
The D2Hs comes with PictureProject, an easy-to-use software application for managing, editing and sharing image files. The D2Hs is also compatible with Nikon’s optional Nikon Capture software package that delivers a unique, powerful and expandable environment for full control over RAW(NEF) files. Nikon Capture 4’s Remote Camera Control function can control most shooting settings and trigger the camera’s shutter release remotely, either connected via the USB 2.0 Hi-Speed interface, or using the optional Wireless Transmitter WT-2/2A. (PTP/IP wireless camera control requires Windows XP or Mac OS X.)
As part of Nikon’s Total Imaging System, the D2Hs is compatible with Nikon’s growing family of digital-exclusive DX Nikkor lenses as well as the lineup of high-quality Nikkor AF lenses. When used with the SB-800 or SB-600 Speedlights, the D2Hs maximizes the potential of Nikon’s Creative Lighting System with high precision flash performance, including i-TTL flash control and support for Nikon’s Advanced Wireless Lighting system.
The D2Hs will be available in March 2005 for an MSRP of $3499.95.

21 Sep 08 Digital Camera Buying Guide
Author: Monty Alexander
Planning to buy a digital camera? Not sure how to get started?
Read on to discover how…..
What do you need the camera for?
If you buy a simple one that can be used at home, you will not get interesting capabilities that you need for taking really good photographic pictures. On the other hand, it would be a waste of your money if you have the latest digital camera only to be used for personal photos at home.
Based on the purpose one can choose from the following main three types.
· Point and shoot: - reasonably compact, with features and size like 35mm cameras.
· Lifestyle: - with moderate features, it’s sleek and compact, so you can carry it around with ease.
· Professional: - with interchangeable lenses, flashes and other accessories, this camera is robust and feature laden, just the right choice for a professional or serious photographer.
These are the important features to look for?
Digital images are made up of dots called pixels. The higher the number of pixels in your image, the better will be the quality of the image. This will therefore enable you to enlarge your image to higher pixel dimensions without creating a pixilated (broken) image.
Compression
Compression shrinks a photo’s file size, thus accommodating more images in the memory card. However compression causes a small amount of data loss. If you need the absolute best-quality images, you have to consider buying a camera that takes uncompressed photos but will accommodate less number of images.
A camera’s memory size will decide the number of images that can be stored. Memory of 128MB will be good enough if you want to use the camera mostly at a social do or a party. If you are on a vacation or when you cannot download images for days at a stretch, a memory of 512MB to 1GB will be most favorable.
Most digital cameras come with at least an optical viewfinder but many digital cameras also come with an LCD screen built into the back. For a digital camera, they vary from 1.5-2.5 inches.
Lens
It is the length of a camera’s lens that determines how much of a scene will fit in a picture. A “Normal” lens is about 50mm, most closely approximate to what your eye sees.
Optical zoom
This enables the photographer to zoom in on an object without any problem in picture quality. Depending on the magnification number, you can zoom in more.
Digital zoom
This feature enables the photographer to zoom in on the centre of the picture by removing the edges of the image.
Focus an exposure
In most cameras, the correct exposure for the lighting conditions is automatically determined. A camera rated ISO 100, has approximately the same light sensitivity as that of a traditional film camera loaded with ISO 100 film. A higher ISO rating means that the camera is more sensitive to light and is potential enough to take pictures in darker settings.
Audio and Movie capture
This feature allows you to record sounds and moving images at the same time, in exactly the same way that a camcorder functions. Some digital cameras provide the facility to record a few seconds of audio with each shot, thus letting you add a personal sound bite to your photos.
Movie mode
This is a feature that lets you take short film clips with your camera. The total record length is typically limited to 10 to 90 seconds.
Most digital cameras come with an in-built flash. Some cameras however include additional features, such as red-eye reduction or night portrait mode.
Image erase
Most cameras also let you select pictures to erase. This handy feature gives you the chance to edit out the photos you don’t want in order to create space in the memory.
Self-timer
A self-timer allows your digital camera for a delayed exposure, usually giving you about 10 seconds before the picture is taken.
Computer connections
Most high-end cameras have software and connections for both Mac and PC computers. However it is necessary to make sure the digital camera you want is compatible with your platform before you buy it.
This feature enables the photographer to capture still images of something moving very fast.
Printing
Nowadays you can buy special printers, depending on the compatibility of your camera, to print off your pictures without connecting it to a PC. This applies both for digital and SLR Professional cameras.
How important is size and portability to you?
Size is another very important factor to consider. If you are to use the camera for non professional purposes the size has to be small as you cannot afford to carry huge sized cameras when you are enjoying a trip.
What is your budget?
Based on the budget the features will vary and the overall offering of a camera. Today’s digital cameras run anywhere from Rs 800 to Rs 30,000, depending on resolution and features. While the initial expense of a digital camera is still high you may find that the added convenience and savings in film and processing costs are worth it.

20 Sep 08 Digital Cameras in Todays Society
Author: Nigel
Digital cameras have become mainstream cameras because they are extremely easy to use and offer a host of wonderful features. Digital cameras connect to PC via USB so you can transfer your photos easily for archiving, editing, and printing. Digital cameras make it easy to share pictures both online and in print. Digital cameras with resolution in the four to five megapixel range are capable of producing professional-quality images.
Cameras
The major advantage of digital cameras is the ability to take multiple pictures at no extra cost and then printing only the best ones. Cameras meant for automatic point-and-shoot photos, with a 3x zoom lens, will serve casual shooters as well as dedicated hobbyists much of the time. Digital cameras with less than one megapixel are inexpensive, but they usually lack key features. Cameras with higher resolutionsof 7, 8, 10 or even more megapixels give you the latitude to create largerprints, or to crop and manipulate images with photo-editing software without degrading them. All digital cameras have a built-in computer, and all of them record images electronically. Since film still provides better picture quality, digitalcameras have not completely replaced conventional cameras. All the fun and interesting features of digital cameras come as a direct result of striving to improve customer needs for high quality, low cost photos.
Images are made up of tiny cells (also called pixels). Images taken at higher resolutions will look much clearer and sharper when printed, and large prints will look better. You can even select only the best and copy them from your computer back onto the camera’s storage device so you can give an edited slide show of just the best images. Once images are in digital form, you can start to take pieces from various images and paste them into other images. Digital photography now makes it possible to put all of your images on the Web and bore the entire world instead of just your friends and family. One nice thing about digital cameras is that you can show your images on a TV set.
Memory Most digital cameras support some type of removable memory card for storing your images. You should buy as large a memory card as your camera can accept, as the memory cards that are included with the cameras are usually not nearly big enough to hold a good number of high quality pictures. Two popular memory card types are CompactFlash and SmartMedia cards. Both types of memory are similar in price and performance but CompactFlash cards are more widely used. How many pictures will fit in the memory. The exact number depends on the size of the memory card (or other type of storage used), the camera’s resolution, the compression quality setting, the exact type of camera, and even the type of pictures taken. If you can’t fit enough pictures in the memory, you should buy a higher capacity memory card instead.
Digital cameras are distinguished by their resolution—how many pixels, or picture elements, the image sensor contains. Digital cameras give you extraordinary control over images. Digital cameras are perfect for learner photographers as the images can be displayed immediately. Digital cameras generally need a computer to manipulate and print images, but the technology is evolving rapidly, and photo printers that work without a computer are now mass-market items. Digital cameras have high power requirements, and over time have become increasingly smaller in size, which has resulted in an ongoing need to develop a battery small enough to fit in the camera and yet able to power it for a reasonable length of time. Digital cameras emerging popularity is attributed to the vastly improved photography experience they afford, through instant viewing, deletion, annotation, and control over reprint size and quantity.

19 Sep 08 Slr Digital Camera: Advantages and Disadvantages
Author: Russ Snapper
A tough decision war happens to all who want to buy a digital camera, whether to buy a compact digital camera or an SLR digital camera. SLR is Digital Single-lens reflex camera, which is a standard tool for professional photographers. It provides the advantage of large, bright and accurate optical finder with large controls and fast operations.
Among the digital cameras, the SLR camera is the best for you provided if you are a family oriented person having a serious appetite for photography. For capturing pictures during family vacations, birthdays and holidays, the SLR camera will be the best companion. Though the point shoot cameras have increased to higher mega pixels, the choice of serious photography hobbyists and photographers is SLR. The clear reason for the choice is that SLR has the capacity for producing artistic photographs.
The main advantage and biggest difference that exit in the SLR is that there are more manual operations than the point-and-shoot cameras have. To get a perfect shot, your camera should be always in ready mode. SLR cameras offer instant start up and also minimum shutter lag. The point-and -shoot cameras have shutter lag of 2 or 3 seconds, which means you can miss a shot. The SLR camera’s shutter lag is less than a second and so you can get all the shots without miss. Another advantage is that the SLR cameras can accept interchangeable lenses. This helps you in getting best shots of sports and nature where you cannot go close for taking pictures. You can zoom the lens of SLR digital cameras and take close-ups. The other advantages are long battery life, high-speed continuous shooting, great image sensor and the ability to save RAW images.
The disadvantage is its larger size and you cannot fit it in your bag or purse. Not only larger in size, but also heavier and not suitable for vacations. It’s also very expensive when compared with compact and subcompact digital cameras. The SLR prices can range between $1,000 and $10,000. The best portrayal of SLR is its speed, clarity and optical system. It can be easily mistaken for a point-shoot camera but it is entirely different in the way it is used and the delivered picture quality. In real meaning, this camera enables you to look at the picture precisely without any alteration of digital features within the camera.
The digital SLR is built in such a manner that it enables to deliver high quality images. In a compact digital camera, the image that you see in the eyepiece or through LCD screen is generated digitally; but in SLR the image is sent by the lens and mirrors to viewfinder that reflects the images from one mirror to another. The digital SLR is versatile and that is why the image seen in an SLR is exact without any alteration. The interchangeable lenses allow you to utilize custom lens for a meticulous shot like Portrait, Landscape and Macro or Micro shots. Some lenses are even available for taking motion shots.
The image sensors in SLR provide good picture quality and quick shoot and click capability with no time lag. Detachable lenses give more attraction for photographers in choosing SLR as their choice. If you are not comfortable with manual operations SLR cameras have automatic settings and this provides transitional steps in learning to use an SLR.

19 Sep 08 Guide to Buying a Digital Camera
Author: Andrew Gates
The digital camera market today offers buyers a large number of choices, with products in widely differing price ranges, sizes and degree of operational complexity. From miniatures the size of a credit card, to fully functional professional SLR (Single Lens reflex) systems, you can buy a digital camera from manufacturers including traditional camera brands such as Canon, Olympus, Nikon, film companies such as Kodak and Fuji, and consumer electronic companies like Sony. Then there are other options that include the mobile phone manufacturers, and webcam suppliers.
The advantages of digital photography are numerous. Topmost is the fact that there is no film processing: expensive both in cost and time. But there is also the advantage of smaller sized equipment, portable media and instant picture viewing. And if you don’t like what you see, you simply delete it and shoot again: no wastage.
If you like to take pictures, being a digital photographer makes a lot of sense. But which camera is the best one for you? In a field of excess abundance, how do you narrow down what you need? How much to pay? How many megapixels? (What are they anyway?) Which brand? How much memory?
Digital CamerasEvery shopper is different.
At MyShopping.com.au we recognise this fact, and so we list practically all brands and models from hundreds of suppliers. These listings include the cold hard digital data facts about each camera and a range of comparative pricings offered by different suppliers. But just as every shopper is different, every photographer is different too. And just having the facts may not make you feel any more knowledgeable about which camera is right for you.
You could begin with the question: What sort of pictures will you take with your new digital camera? This is a valid starting point because from here you can begin to qualify your requirements in terms of technical capability and price. What sort of pictures will you take with your new digital camera?
Is it simply for happy snaps whenever you get together with friends and family at weekends and holidays? Or are you a serious bird watcher and you want to capture nature at its finest? Perhaps you want a camera for work to record your inventory, or recording information from a client. Maybe you’re a PI on a mission. The point is, you need to begin by recognising that your reason for buying a digital camera may not be the same as that of your best friend who is recommending the model she bought.
Once you’ve figured out the sort of pictures you are going to take, you can then set about deciding on the type of camera that will meet your needs. If you need something highly portable that fits in your shirt pocket or your handbag and lets you take it anywhere you go, make size a big consideration. If you want to take seriously good photographs, and you want to pursue an artistic endeavour, make image flexibility your main concern.
It might also be worthwhile considering your own position in the digital photography experience. Are you a novice about to buy your first camera, do you have some intermediate experience, or are you an advanced user?
Someone new to the market will likely not want to spend a lot of money, nor have a lot of mind-boggling features that leave you confused. There are cameras ideal for beginning users that have basic ‘point and shoot’ features including optical and digital zoom lens, flexible storage media and built in flash. There is a huge range of cameras available with simple features at low cost.
If you consider yourself an intermediate user with some operational knowledge of digital camera technology, you may want to consider more advanced features that give you more control over the pictures you take. These features usually come in a range of automatic settings and manual settings for capturing the image and different storage options in terms of resolution and picture type (raw data, jpeg, tiff). Naturally there is some cost attached to additional features when compared to more basic cameras.
For advanced users, there are a lot of professional options you can consider; such as SLR view finding and lens interchange ability. Cameras in this range provide much greater control over the image, both before and once it is captured. These options include shutter speed and aperture adjustment, and many cameras offer the ability to manipulate images ‘in camera’, such as cropping, and brightness and contrast adjustments.
After the picture is taken
A further main consideration is what are you going to do with your images once you have them? The great beauty of digital photography is the simple fact that you can store them on digital media such as CDs and media cards, and view them on computer screens and in many cases, your television. You need print only when and those you want to see, or show to others. Digital photography also gives fantastic opportunities to manipulate your images using popular image manipulation programs, resizing them, altering brightness and contrast characteristics, and correcting problems such as red eye, or removing skin blemishes.
Most digital cameras are computer ready, able to plug directly into your PC or Mac using USB connectors. They usually include proprietary software allowing you to easily and instantly manage your image files in photo albums or slide shows. Many digital cameras also include a video capture facility enabling you to take short motion pictures.
What you want to do with your images after you have them can have an impact on your choice of camera. If you want to make enlarged prints for example, you will want a high megapixel capacity (also talked about as ‘resolution’). If you want images for website use, you will want to get the best quality images that can be reduced in resolution without severe degradation.
Beauty is in the “I”
Great pictures usually come from great conditions. You capture a great moment, the light is just right, the subject is at the perfect distance, the image is perfectly framed. But not every digital camera offers the flexibility to make the best of existing light conditions, or position. Most digital cameras (certainly at the budget end) come with a built in automatic flash, which is terrific for happy snaps in darkened environments. And the automatic flash automatically does not ‘go off’ in bright sunny conditions. But in those times when you want to use the existing light, you need a camera that gives you manual control over the operation or not, of the flash.
Moreover, most digital cameras in the lower and medium price ranges are highly automated. If you are moving from a traditional SLR film camera where you have maximum control over shutter speed, aperture and ISO speeds, it may be frustrating to not have easy access to the same range of tools to take advantage of existing light conditions.
In the more advanced (and therefore more expensive) range of digital cameras, most lens and aperture functions are available in exactly the same way as other SLR systems. What differs is how the colours and light of the image is translated through pixel capture compared to the chemical processing systems.
You may want a wide range of focus options. Most digital cameras have two different types of image magnification, lens magnification (zoom) that may be equivalent of a 35mm to 150 mm lens, and a digital magnification that may be to ten-fold (expressed as x10). This provides you with zoom lens capability, which may be limited in its depth of field control and is subject to soft focus and movement if the conditions aren’t just right, and a digital magnification of the pixel image. If being able to capture magnified distant images is important to you, you need more megapixels, and a lens system that gives you some control over its focus and aperture management.
A final word on accessory
Digital cameras are electronic equipment. That means they run on batteries, and if you use your camera a lot, you will find that you will be frequently replacing batteries. Some cameras have rechargeable batteries; others simply use dry cells (AA), which you can of course load with rechargeable ones. It pays to have spare batteries so that you always have a charged power source. Some cameras have docking stations to help manage the connection with computers. Many digital SLR cameras have interchangeable lens systems, some of which may be compatible with traditional film SLRs.
You can also print your own pictures at home with special printers that handle standard photograph paper, and connect directly to your camera. Although it may be less expensive to simply take your camera’s card, or a CD to your local camera store, and now many supermarkets and department stores, and use the automatic printing machines to print the images you want.
There is a lot you can do with a digital camera, and you can pay les than $200, or more than $10,000. It all depends on how you see yourself as a photographer, what you’re shooting, and what you want to do with your pictures.

18 Sep 08 What Digital Camera to Buy? Tips to Help You Decide
Author: Ralph Serpe
Digital cameras are available in a variety of different sizes, colors, brands, zooms, resolutions, etc. The features are endless. There are so many features available in today’s cameras that many first time buyers become overwhelmed and have no clue what digital camera to buy.
So what should a beginner digital photographer look for when buying their first digital camera?
In order to answer this question let us pose a few more:
WHAT KIND OF PICTURES WILL YOU BE TAKING?
This is an important first step in deciding what digital camera to buy. If you are planning on becoming a professional photographer and will be taking high quality shots to possibly sell, any old digital camera will not do. You will have to pay careful attention to the types of features you will need like resolution, megapixels, zooming, etc.
If you are a casual photographer and simply want a descent camera to share with friends and family then you may not need a bunch of fancy gadgets and features.
WHAT IS YOUR BUDGET?
No matter what your needs and wants are as a photographer your finances will ultimately dictate what type of camera you can afford. Set a budget and stick to it.
WHAT RESOURCES WILL YOU NEED?
Depending on the digital camera that you purchase, you may need additional resources to use it to its full potential. If you plan on doing any photo editing or printing, you will need a computer and a printer that is compatible with your camera and software. The editing software is usually included with your digital camera but other devices like memory cards are usually not.
WHAT RESOLUTION WILL YOU REQUIRE ON YOUR CAMERA?
Before you buy your first digital camera make sure you learn more about its capacity to produce high quality images. This is determined by the number of megapixels the camera has. The more pixels, the higher the resolution. This is important because you want your images to retain their quality when you enlarge them.
HOW MUCH MEMORY WILL YOU NEED?
You will need a memory card for your digital camera in order to store your pictures. When you buy a digital camera, make sure it has a card slot for external and additional memory. This allows you to change full memory cards conveniently while shooting your pictures.
WHAT ABOUT THE LOOK AND FEEL OF YOUR CAMERA?
Buy a camera that you are comfortable holding while taking pictures. So before you actually purchase your digital camera, make certain that you actually pick up and test each camera. Consider where the buttons are located and how they are spaced out and see also if you feel comfortable using the view finder. See how heavy it feels around your neck as well.
WHAT ABOUT THE BATTERY LIFE OF YOUR CAMERA?
Digital cameras use up battery life rather quickly and batteries are not exactly cheap. Make sure you purchase a camera that uses rechargeable batteries, this way you can get multiple usage out of your batteries. Take also into consideration an AC adapter when you buy a digital camera. You can attach this to the camera when you are viewing your pictures or uploading them.
WHAT ABOUT THE LCD SCREEN?
The LCD is a small screen usually located on the back of the camera. You can use the LCD screen instead of looking through the traditional tiny viewer. The LCD screen also enables you to preview pictures that you have already taken. There is a drawback to using an LCD screen however, as it does use up a lot of battery power.
DO YOU NEED ANY SPECIAL FEATURES?
You should consider whether or not you will need any special features on your camera. This all depends on what type of pictures you plan on taking. If you want your camera to have good zooming capabilities, you can opt for those with optical zoom lenses. Other features such as remote control, tripods, etc. can also be considered when you buy a digital camera. Be careful though. The more features you have on a digital camera, the more difficult it will be to figure out and use.
With this information I do hope you will be able to figure out what you need before you buy your digital camera. I feel the most important thing is to be patient. Take your time shopping and researching. Learn everything there is to know about the features of digital cameras and what you really need.
Once you narrow down your choices to a few different models, look for the best possible price. There are many different camera sellers online and off. But don’t buy a digital camera from just anyone. Make sure the seller has a good customer service history as well as good prices. Best of luck in figuring out what digital camera to buy!

18 Sep 08 The Early Digital Camera
Author: Roberto Sedycias
A digital camera is basically a digital device that enables images to be captured. Digital camera images are stored electronically rather than on film. This process involves converting light into electrical charges, and then translating this back into the image that was seen through the digital camera LCD. Although the digital camera is a recent addition to the world of photography, the concept of the possibility of a digital camera was begun in the 1950s.
The early concept of the digital camera was closely linked to television technology. It began with digital images being recorded on scanners and in the form of digital video signals. In 1951 broadcasting companies were recording images as electrical impulses and onto magnetic tape from their television cameras, and this paved the way for digital camera technology to begin. By 1956 electrical impulse recordings were common practise within film industry, and camera manufacturers began to dream of a digital camera device.
The first record of a patent for a type of digital camera was in 1972 when Texas Instruments patented a camera that did not require film. However, the patent revealed a more analog based design rather than a digital camera, and there is no record of whether the camera was actually created. What the patent does show, however, is that interest towards a digital camera was growing with the idea that the need for film could be removed. A pioneer in the history of digital camera was Steve Sasson, an engineer at Kodak. Digital images were of the moon were being transmitted via satellite by NASA, using a mosaic photo sensor, and he saw the possibility of a digital camera for commercial use. In 1972 he began to group together available equipment used within the film industry to create an image digitally rather than on film.
Central to this early concept of the digital camera, and still used by digital cameras today, is the Charged Coupled Device. The CCD detects light and colour intensity and then converts this information into electrons. The value of each cell in the image is then read, and converted to binary format to make the image computer compatible. Steve Sasson produced his first digital camera image in 1979. The image took a total of 23 seconds to take, and a further 23 seconds to read from the playback unit. Although the digital camera image was less than perfect, it showed that the digital camera was a possibility. Kodak had developed a camera that developed picture from light, but it was never manufactured for the public.
The first camera to be marketed was the Sony Mavica electronic still camera in 1981. It was not a true digital camera as the image was recorded on mini disc, and then attached to a television or video. It was more a freeze frame video camera but it greatly influenced people`s attitude to the recorded image. It made public the possibility of a camera that stored images using techniques other than film. It still used more television technology but was the first hand held with the general idea of digital camera usage. Cameras that could transmit images via satellite became popular, but were used by the media only due to the expense incurred. The possibilities were becoming apparent and images were used for news coverage. The first camera for general use with a computer was the Apple Quicktake 100 camera which appeared in1984. In 1986 the Canon RC-701 was used for coverage of the Olympics, with quality images printed in the newspaper. This showed the possible quality, and the desire for the digital camera was born.
The first mega pixel sensor was invented in 1986. It contained 1.4 million pixels and was suitable for a digital camera image measuring 5×7 inches. In 1987 accessories for storing, printing, manipulating, transmitting, and recording digital images came onto the market, with the Fuji DS-P1 arriving in 1988. This is arguably the first true digital camera as recognised today, boasting a 16MB memory card. With the arrival of JPEG and MPEG standards in the 1990´s, the face of the digital camera was changed for ever. Kodak marketed the first readily available digital camera that met all standards, with the Kodak DC40 in 1995.
