19 Sep 08 Digital Cameras - How They Work
Author: Ted Burns
Digital cameras come in various sizes, shapes, and specifications and offer a variety of impressive features.
Digital cameras are quickly gaining popularity around the globe. Many people already own one and routinely use it for their own pictures. Their use have become part of the culture among many communities and industries.
Digital cameras also have become part of a broad package of combined features with other hand-held tools, such as PDA devices and cellular phones. This makes the use of both devices much more convenient, having them combined in one, rather than two or more, functional instruments.
Digital cameras, moreover, not only can be used for still photos as with conventional cameras, but also for taking videos. An owner needs only to upgrade the camera’s memory card to increase storage capacity.
The marketplace offers a number of digital camera brands that provide a wide range of features. Olympus, Canon, Nikon, Kodak, and HP are some of the better-known brands of cameras offering the conventional 35mm to digital. Other key camera manufacturers include Sony, Panasonic, and Casio.
Digital Camera Considerations
Differing from conventional cameras, digital cameras have a small LCD screen, and sometimes an LCD screen plus viewfinder. The LCD screen is similar to TV screens that allow the photographer to see the picture, even before snapping it. Some have large screens that enable the photographer to see more of the subject and background.
Digital cameras also come with memory slots that hold a memory card or “stick.” The amount of memory available in them ranges from megabytes to gigabytes. Of course, the more memory, the greater the cost. However the extra storage capacity may be well worth the additional expense.
Another purchasing concern is the battery. Some digital cameras use disposable batteries. However, they wear out quickly, so most people recommend rechargeable batteries for longer energy life. Typically a rechargeable battery and a charger come in bundle with the camera unit.
Finally, consider the way the pictures are downloaded. Though many digital cameras come with a USB port which easily connects to a computer, there are others that necessitate removing the memory card and positioning it with a reader to download pictures.
Digital Camera Features
Camera buyers should know at least the basic features of their camera of choice before making an expensive purchase. Though the snapping of pictures is fundamentally the same from camera-to-camera, there are features that make one brand more appealing than others.
For example, the number of mega pixels used when taking pictures - meaning millions of pixels that help with the clarity of the pictures - should be one of the primary considerations to most buyers. Pixels are the individual “dots” that make up the content of pictures.
As such, cameras offering a greater number of pixels can produce larger images with better resolutions than those with less. Be aware, though, that cameras using a more pixels consume more camera memory when storing the images.
The camera’s zoom function is also critical. Most digital cameras are enhanced with a two-zoom capability; the optical and digital. Optical zoom uses a moving lens and makes the subject in the picture appear closer, while digital zoom crops or stretches the image.
Finally, don’t neglect the importance of the camera case’s durability. Some digital cameras are made predominantly of plastic materials - and are consequently more fragile - while others are comprised of a combination of plastic and metal alloy.
Either type has limitations in the amount of jarring that can be sustained without internal damage. Spend a little extra money to purchase a case that will protect your camera investment.

19 Sep 08 Digital Camera Basics-resolution, Exposure, Focus, and Storage
Author: Brian Lee
The amount of detail that a camera can capture is called the resolution, and it is measured in pixels. The more pixels a camera has, the more detail it can capture and the larger pictures can be without becoming blurry or “grainy.” High-end consumer cameras can capture over 12 million pixels. Some professional cameras support over 16 million pixels (megapixels), or 20 million pixels for large-format cameras. For comparison, it has been estimated that the quality of 35mm film is about 20 million pixels.
Exposure and Focus
Just as with film, a digital camera has to control the amount of light that reaches the sensor. The two components it uses to do this, the aperture and shutter speed, are also present on conventional cameras.
Aperture: The size of the opening in the camera. The aperture is automatic in most digital cameras, but some allow manual adjustment to give professionals and hobbyists more control over the final image.
Shutter speed: The amount of time that light can pass through the aperture. Unlike film, the light sensor in a digital camera can be reset electronically, so digital cameras have a digital shutter rather than a mechanical shutter.
These two aspects work together to capture the amount of light needed to make a good image. In photographic terms, they set the exposure of the sensor.
In addition to controlling the amount of light, the camera has to adjust the lenses to control how the light is focused on the sensor. In general, the lenses on digital cameras are very similar to conventional camera lenses — some digital cameras can even use conventional lenses. Most use automatic focusing techniques.
The focal length, however, is one important difference between the lens of a digital camera and the lens of a 35mm camera. The focal length is the distance between the lens and the surface of the sensor. Sensors from different manufacturers vary widely in size, but in general they’re smaller than a piece of 35mm film. In order to project the image onto a smaller sensor, the focal length is shortened by the same proportion.
Focal length also determines the magnification, or zoom, when you look through the camera. In 35mm cameras, a 50mm lens gives a natural view of the subject. Increasing the focal length increases the magnification, and objects appear to get closer. The reverse happens when decreasing the focal length. A zoom lens is any lens that has an adjustable focal length, and digital cameras can have optical or digital zoom — some have both. Some cameras also have macro focusing capability, meaning that the camera can take pictures from very close to the subject.
Digital cameras have one of four types of lenses:
1) Fixed-focus, fixed-zoom lenses - These are the kinds of lenses on disposable and inexpensive film cameras — inexpensive and great for snapshots, but fairly limited.
2) Optical-zoom lenses with automatic focus - Similar to the lens on a video camcorder, these have “wide” and “telephoto” options and automatic focus. The camera may or may not support manual focus. These actually change the focal length of the lens rather than just magnifying the information that hits the sensor.
3) Digital-zoom lenses - With digital zoom, the camera takes pixels from the center of the image sensor and interpolates (alters) them to make a full-sized image. Depending on the resolution of the image and the sensor, this approach may create a grainy or fuzzy image. You can manually do the same thing with image processing software — simply snap a picture, cut out the center and magnify it.
4) Replaceable lens systems - These are similar to the replaceable lenses on a 35mm camera. Some digital cameras can use 35mm camera lenses.
Most digital cameras have an LCD screen so you can view your picture right away. This is one of the great advantages of a digital camera — you get immediate feedback on what you capture. Of course, viewing the image on your camera would lose its charm if that’s all you could do. You want to be able to load the picture into your computer or send it directly to a printer. There are several ways to do this.
Although most of today’s cameras are capable of connecting through serial, parallel, SCSI, USB, or FireWire connections, they usually also use some sort of removable storage device. Digital cameras use a number of storage systems. These are like reusable, digital film, and they use a caddy or card reader to transfer the data to a computer. Many involve fixed or removable flash memory. Digital camera manufacturers often develop their own proprietary flash memory devices, including SmartMedia cards, CompactFlash cards and Memory Sticks. Other removable storage device include floppy disks, hard disks (external, or microdrives), and writeable CD’s and DVD’s.
Regardless of what type of storage they use, all digital cameras need lots of room for pictures. They usually store images in one of two formats — TIFF, which is uncompressed, and JPEG, which is compressed. Most cameras use the JPEG file format for storing pictures, and they sometimes offer quality settings (such as medium or high).
To make the most of their storage space, almost all digital cameras use some sort of additional data compression to make the files smaller. One compression routine takes advantage of patterns that repeat. The image can be reconstructed exactly as it was recorded, reducing the file size no more than 50%, often much less. Another compression routine called irrelevancy eliminates some of the more meaningless data, taking advantage of the fact that digital cameras record more information than the human eye can easily detect.

18 Sep 08 How to Buy Discount Digital Cameras
Author: Russ Snapper
Many brands of discount digital cameras are available from manufacturers such as Kodak, Fuji, Nikon, Olympus and Canon amongst others.
Why these cameras are discounted? The reasons could be like they have been over purchased with a lot of stocks left or it could be a means of making you enter their store. Websites use discounted items to grab your attention to their website many times. Online purchasing has emerged as a large market and it can save some money to the company when you purchase online. As expenses such as opening a store, paying out salaries for employees, purchasing shelves and other fixtures are not incurred, these savings can be passed on to you to some extent.
By saving money on the purchase of discount digital camera, you will feel great as by not paying the full price, you still have the same quality. The digital cameras are exactly the same as the difference here exists only on the price. Hence, why should you pay an expensive price as you can get the same camera when you purchase it on a discount? With the money thus saved, you can buy other great add-ons for your digital camera.
Finding discount digital cameras is easier over websites. The question is which digital camera to choose. You can find discount digital cameras from most major digital camera manufacturers. You should have a basic idea of the options, features and brand name of the digital camera you want to buy. You can also find from sale bills and newspapers about different types and brands of digital cameras along with the prices offered at many stores. Some times, though the deals are advertised over the web, they may not have them in their stores. Earlier the digital cameras had one thing in common when compared with non-digital cameras, (i.e.) an expensive price tag. However the cost of digital cameras has dropped so much recently that you can purchase a digital camera for less than $250.
When buying a discount camera, you have to be aware of at least the buzzword ‘Megapixel’ related with digital cameras. Megapixel refers to the number of pixels available per million or the resolution of the image. This is important to be considered because Megapixel directly relates to the image quality obtained. The factors such as budget, mega pixels, exposure control, battery life, user controls and Zoom lens are all important while making a choice of a camera and to get the best out of it. Knowing these features will save you time when you start looking for a discounted digital camera.
You have to understand also the type of software that is needed for the discount camera you have planned to buy. Because all digital cameras do not use the same software for storing or to transfer the photos from the camera to the computer. Make sure that the software supplied will be compatible with your computer, without the need for upgrading your older computer for the sake of having the photos on your computers.
If you don’t have an idea of the features you need, you can also then search by brand name of the digital camera and read all about the various models offered. Still, Price should not be the only factor when you shop for discount cameras, but also certain basic features.

18 Sep 08 Top 20 Questions to Consider When Buying a Digital Camera
Author: aldrin garcia
My top 20 key questions to ask yourself when buying a digital camera.
1. How many “megapixels” /resolution?
Once and for all, at least to me, you have to get the highest resolution your money can buy at the time you buy. Period.
2. Who made the lens?
Most cameras will give you an idea where the lens was made just by looking at the front of the lens. Know if the lens of your camera came from a reputable company like Leica, Zeiss, Canon, Etc… Lens quality is one of the most important factors you should consider especially if you’re going to use it for commercial, technical or scientific purposes.
3. Will I need interchangeable lenses? How many are available for my specific camera in mind?
Having the option of interchangeable lenses gives you the freedom to experiment with different kinds of focal lengths. Although some P&S (point and shoot) cameras can rival DSLR’s with a generous zoom range for a non interchangeable lens system.
Also note the number of lenses available for use with your specific camera because of flexibility reasons. You can practically cover the entire “zoom range” with interchangeable lenses versus modest zoom ranges on non interchangeable lens systems or P&S cameras.
4. Does it have a zoom capability? What’s the range?
Almost all applications that I listed above will need some form of zooming in (telephoto) or out (wide angle), especially if you don’t have the space to move around the object you are shooting.
For Landscape shots, wide angle shots are very common and appealing while zooming in on the details serves as a break and complements the wide angle shots.
For weddings and events, you need a zoom because there will be times where you are limited by the shooting space and you will have a difficult time moving around. Its a good thing to know that you can do all sorts of framing without even moving from your position.
A nice zoom will give you the efficiency and versatility in your photography, so my suggestion is to go for the longest range you can get (usually from a 7X to a 10X for Point and Shoots).
Also note the speed of zooming in or out as this will be a factor if you’re shooting events like weddings. You will fail to capture that “decisive moment” on a mediocre zoom speed.
5. Does it have the provision to capture raw images?
Many photographers will say you’ll need this digital camera feature if you want to have big prints from your pictures. Although this is correct, the main reason why you will want this is because of the benefit it will give you…pure total control of your pictures… from exposure, color, metadata, hdr and a lot more.
6. Can I attach an external flash?
Having an external flash capability will give you the power and creative freedom to light your subjects any which way you like.
You can connect your digital camera to all sorts of lighting equipment thus giving you more options and versatility. This comes in the form of a hotshoe or a PC-Sync socket.
If your digital camera doesn’t have this feature, there is still hope because accessories called flash slaves are being sold by third party companies in different flavors that will also do the same job more or less.
7. Does it have a tripod socket?
Some of the most beautiful landscape pictures that I’ve seen are undoubtedly made with a tripod, so this is a must have if you are planning to do this kind of photography.
The “available light shots” in a wedding, still life and product shots, studio and fine art shots … all need a tripod for successful execution… so guess what happens if you don’t have a tripod socket?… You cannot effectively use a tripod!
8. Does it have automatic and manual focusing?
It will not be evident at first why you’ll need this especially if you’re just starting out in photography. But if you’re like me… A total control freak when it comes to cameras… and you really want to express your creative side, this is definitely a must have.
9. Can you attach filters to it? and what filter size?
Creative expression through special effects is just one of the many reasons that makes photography fun and interesting, and experimenting with filters is one creative pursuit you should try with your photography especially if you’re a beginner.
Always remember to ask if the particular digital camera you are eyeing for can handle filters and ask for the filter size. (To save you from buying the right filter with the wrong filter size) Please note that most Digital SLRs should be able to to handle filters as most lenses that come with it have a filter thread built into the lens.
Most P&S (point and shoot) digital cameras normally doesn’t have a filter thread built-in and might need special accessories to accomplish this so you should check to know for sure.
Again, there are many third party accessories that you could buy to adapt filters to your P&S digital cameras that don’t have this provisions. I’ll discuss all about this in a future post so watch for it. (Or subscribe to my announcement list (feed via email) so you’ll know when it’s up.
10. Can I upgrade the firmware?
The good thing about some digital camera manufacturers is that they keep on improving their digital cameras even after they sold it to you… this comes in the form of a firmware upgrade.
Usually this involves an improvement on one or many features of a camera. Be sure that the digital camera you’re planning to buy has an easy way of upgrading its firmware. This comes in the form of either an easy download via the manufacturer’s website (find it and bookmark it now) or a FREE CDROM.
Another caveat - be sure to consider if a downgrade is also possible or available with your digital camera… Why is there a need a downgrade you ask?… Because, you may want to reinstall an earlier firmware… just in case you don’t like the results from a firmware upgrade.
Occasionally there’s a feature that will be removed by the upgrade that you failed to read about and you decided that you just want to keep that feature instead of a bunch of trivial upgrades from the new firmware. (Yes, I personally experienced this.)
11. Are there extra goodies or software that come with it?
Some people ignore the fact that you can save a lot of money just by doing a simple arithmetic. Did you know that you could actually get your digital camera for a lot less if you study the deals and offers on the marketplace?
If you buy a digital camera and it comes with software that you can really use… like photoshop, elements, or any other image editing software for that matter, then you already saved some money you would otherwise spend. Some dealers will throw in lots of extras… If you just simply ask.
Always try to ask for these things that you’ll end up buying anyway if you don’t - like camera bags, extra lenses, extra batteries, memory cards, tripod, lens cleaners etc. Trust me… you will end up buying these things if you don’t ask for it on the deal. What have you got to lose? Simply ASK. Would you believe that I effectively lowered one of my camera purchase cost by as much as 30%? Ask away.
12. Is there Local Support in your area?
Finding the answer to this one will give you a great benefit in the long run. Wouldn’t you sleep better at night because you feel that extra security - that in case there is something wrong with your digital camera, you can bring it in for repair at a moments notice?
Not knowing when your camera will be repaired (or if it even arrived at a distant repair facility) is one of the worst feelings a photographer can have especially if you’re in the middle of a photoshoot or project.
13. What type of warranty does it have? Worldwide / Countrywide?
If you travel a lot its good to know that a countrywide or even better - a worldwide warranty can get your camera fixed wherever you are. Always bring the warranty card and glue it on your camera bag.
14. Does it have the ability to take video and audio?
I know, most DSLRs don’t have this function. But some non interchangeable lens DSLRs have it. This is a very useful feature to have if you’re on a project or photoshoot and want to document or record a procedure, a moment, or an idea that you would otherwise have trouble remembering or even writing. It’s always a good idea to bring a P&S camera backup that have this function.
The things that you could do with audio and videoclips on a photoshoot are only limited by your imagination… interviews, documentation, funny quips, training procedures, bloopers, etc..
15. Does it have a manual white balance?
White balance is one of the most interesting aspects of digital cameras. Its fun and fascinating to work with. Having this option puts the photography fun-o-meter way way up. In future posts, I will be discussing white balance in detail so be sure to stay tuned.
16. How sensitive is it to infrared?
If you’re planning to make infrared pictures or enter the exciting world of Infrared fine art photography then you’ll want to know if your digital camera can do it.
TIP: There is a simple way to test how sensitive your digital camera is to infrared using a very common device - a TV remote control. For P&S, you can aim the remote control towards the lens and gauge how bright the LED from remote is. This should give you an idea how sensitive your digital camera is to infrared. For DSLRs you will need to take shots of the LED and experiment a little or you can simply research or google the particular camera model you have in mind for other people’s experiences and thoughts about it.
17. How high is the ISO sensitivity? Is it manually adjustable?
ISO sensitivity is a term referring to the sensitivity of film to light. In the digital camera world, it refers to the sensitivity of the electronic sensor in your digital camera in relation to the ISO standard used for film.
The higher the ISO sensitivity of your camera the faster or better it can record a specific amount of light.
High ISO sensitivity is useful for taking better pictures in dark settings… such as inside a church or at night. The higher the ISO setting, the more details you can capture of a dark scene.
One caveat - take note of the amount of noise a particular camera exhibits at higher ISOs. Some people like it and some don’t. Again, don’t be afraid to ask or do research on the noise characteristics of your camera model in mind to see if this is the right choice for you.
18. How high or low can you set the shutterspeed? What are the minimum and maximum aperture settings?
Shutterspeed and aperture settings are the basic mechanisms that drive your camera and controls the amount of light that is exposed by the film or image sensor.
You use high shutterspeeds in action shots and to prevent camera shake, and you use low shutterspeeds for movement effects and bulb or long exposures. You can check for these figures on the websites that I gave you in part 1. You can see it in the technical specifications for a particular camera.
A bulb or “T” function is a nice feature to have because you can take exposures for virtually very long periods of time. Another feature to have is if your camera has a remote control to use this bulb or “T” mode. This gives you the capability to take pictures without holding your camera and adding to the “camera shake”.
With the subject of apertures, a small one (small aperture opening) lets you have a wider depth of field so your shots are sharp from near to far versus a large aperture (big aperture opening) where your shots have a narrow depth of field and appear “selectively focused”.
19. Does it have some form of an image stabilizer?
New cameras coming out as we speak often have this feature. Simply put, an image stabilizer is some form of a mechanism built into the lens or the camera body (depending on the manufacturer and their implementation) that basically prevents you from getting blurred pictures when taking pictures in low light or you are using a long or telephoto lens. Having this feature can mean the difference between a blurry picture (aka no picture!) to a usable one.
20. How close can it focus? Macro abilities?
The closer your camera can focus… the bigger the picture of an object you can take in relation to the image dimensions of the final photo… and the bigger the picture of the object… the more detail you can get. If you want to take pictures of small objects such as flowers and fine details then this is a must-have.
That’s it. Whew.
Do you really have to go over all these questions?… Of course not, but even if you only study and ponder on half of them…and take the time… I promise you that one thing will surely happen…
You’ll be…
a lot smarter!
than when you first started asking these questions… ergo you’ll be in a better position to decide what digital camera to buy… Because you are now armed with the most powerful tool anybody can have
the power of information!
In any case, I hope you find as much value in these questions as many of my friends have and be able to get the camera of your dreams.
Enjoy!

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.

17 Sep 08 The Early Digital Camera
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.
