Until recently, were you to ask someone if they knew how to operate a digital camera, they would react as though you had grown another head. A digital camera? Whoever heard of such a thing. Now, in less than 5 years, they’re the only kind of camera to buy. With digital photography there’s no need for endless rolls of film. You just focus, click, and presto, a digital image. Don’t like the picture you just took? That’s no problem, either. You can simply delete the image.
Now, with all this available technology, why should we ever worry about pictures again? Well, the plain truth of the matter is this, if you don’t have a computer, it’s still expensive and quite time consuming to download your pictures at the local Wal-mart (or Wal-greens), instruct the computer there to copy the pictures to a disk, and then pay for the actual printing. See, it’s at this point that most consumers realize it’s just downright easier to buy an old fashioned, film loaded, camera.
Let’s assume, however, that you do have a computer, and you do want to purchase a digital camera. What kind of camera do you need? Where do you begin to check out your options and see how they relate to your needs? Well, the first part of the process would be to visit an electronics store in your area. The stores that specialize in electronics will generally have a sales person on hand that can explain all the available features of a digital camera and help you decide what you need and what you can live without.
One of the big questions concerns the “megapixel” feature of the camera. The larger the megapixel number, the better the quality of the picture. You see, megapixel determines how the camera reads color combinations in order to produce the best photo possible. Now this might be a matter of great concern if you are a professional photographer, but to the everyday consumer, three or four mega pixel strength is all you need.
Next you’ll want to examine what types of subjects you will photograph and under what kind of conditions. Do you need a camera that makes pictures of moving objects? Are you making your pictures at night, or during daylight hours? Up close and personal, or over on the next block? All of these questions are valid and will affect the quality of the picture you get if not correctly addressed.
There is one final option that you might want to check: some of the digital cameras also do video. The cameras tape the audio and video of the moment as well, or better, than some of your larger video cameras, just not as expensively.
Last but not least, you need to understand your storage options, and determine how much storage space you need. Going to the family reunion, room for maybe 10 pictures will be enough; But now the class reunion, well you’re going to need room for at least 500 photos. Alright, that brings this topic to a close and moves us on to the subject of “memory stix”…….

Digital Cameras: Do You Know Your Megapixels
Choosing A Digital Camera Printer
by: Steve Gargin
There are so many types of digital camera printer on offer that finding the right one for your personal and business needs can be a very daunting task. However, there are a few main points to consider when choosing a digital camera printer that will help make the process a little easier.
It isn’t necessary to have a high-resolution digital camera printer to make great pictures. The higher the printer resolution you use, the more pixels you'll need in your original image file to produce a decent size print with your digital camera printer. The actual file size (in pixels) of the image from your camera, divided by the printer resolution (in dots per inch), determines the final print size. So, if the image file size is 1,478 x 1,280 pixels, and you print the file at 163 dpi with your digital camera printer, the final print size will be 9 x 7.8 inches.
If your digital camera printer resolution is 300 dpi, then you will have a higher resolution with more dots per inch laid down on the paper but a smaller print size. It is therefore important to ensure that you have the image file size to support the resolution of your digital camera printer.
The price of a digital camera printer is lowering whilst the quality is increasing. If you choose the right digital camera printer you can have your own photo lab, greeting card designing and sign making department with just your digital camera, some software and a printer.
The aim of having a digital camera printer is to produce photographic prints that look as close to real photographic prints as possible. This type of digital camera printer was once very expensive to buy and run, but technological advancements and competitive pricing have made them much more accessible to the average buyer. Ink-jet printers are now available that can produce excellent prints and a near photo-quality printer is much easier to find for people with a small budget. You will probably want to have a digital camera printer with a scanning feature built-in. If you want to produce same-size scans of photos you don’t need scan resolutions higher than 300 samples per inch for the scanner.
Your digital camera printer should also have the same interface that you already have on your computer. So if you have USB, then get a digital camera printer with USB, a Firewire printer if you have Firewire or a SCSI printer if you have SCSI. There should be no need to buy a digital camera printer that requires a different interface to the one you already have on your computer or it will cost you more to upgrade if necessary.

Canon Digital Camera Guide
by: Steve Gargin
Canon digital camera innovations have always been at the forefront of photographic innovations and their compact digital cameras package a variety of functions into a deceptively small Canon digital camera body. These are particularly attractive to a wide range of users because of their light weight, ease of use, high image quality and high functionality. Canon digital camera experts are highly experienced in camera manufacturer, leading-edge optical technology, ultra high-precision mounting technology, electronic device technology and color management technology amongst others. All of this experience and expertise is combined to produce the Canon digital camera PowerShot series and the PowerShot DIGITAL ELPH/DIGITAL IXUS series.
Throughout their continuing research, the Canon digital camera development team has collected a large amount of photographic data and also made broad statistical analyses of the frequency involved in taking photographs. This data led to the creation of the Canon digital camera Photographic Space which is a graphical database of information relating to the relationship between surrounding brightness and distance between a Canon digital camera and the subject relative to the focal length and position of the zoom lens when pictures are taken.
The Canon digital camera Photographic Space led to the development of a new scene-recognition technology called "iSAPS" (intelligent Scene Analysis based on Photographic Space) Technology. Canon digital camera iSAPS Technology analyses the scene to be photographed and makes optimal adjustments of a number of key functions, including auto-focus, before the shutter is pressed.
The Canon digital camera iSAPS Technology closely estimates the camera-to-subject distance based on the lens focal length, zoom position and surrounding brightness which guarantees the most accurate exposure and white balance settings for the overall conditions.
At the high end of the Canon digital camera range are their single-lens reflex, or SLR, cameras. The Canon digital camera company has created ultra-high-precision imaging elements and high-performance digital imaging engines so that their digital SLR cameras possess the same ease of operation as their 35mm film counterparts but produce exceptionally high-quality images.
The Canon digital camera imaging engine, or DIGIC II, creates image data from signals output from a CMOS, or complementary metal oxide semiconductor, sensor. The CMOS sensor is really the brain of any digital camera. Canon developed the Canon digital camera DIGIC II high-performance imaging engine directly due to the increasingly high resolution CMOS sensors. With the help of a high-capacity DDRS DRAM (double data rate SDRAM) as the buffer memory, the Canon digital camera DIGIC II processes high-resolution images at ultra-high speeds.

Buying Digital Camera Batteries
by: Steve Gargin
A digital camera battery is probably the most important digital camera accessory. Some digital cameras can consume power at an alarming rate, providing no more than a few hours of continuous shooting time before the battery is drained. Other cameras are renowned for the long life of their digital camera battery which allows users to snap away with barely a thought to power consumption. It is important to know how you intend to use your camera and what type of battery it needs.
There are two types of digital camera battery. The most widely available digital camera battery is a standard AA-size battery. The other type of digital camera battery is a rechargeable battery that is made by the manufacturer, otherwise known as a proprietary battery.
A proprietary digital camera battery offers the advantage of being lighter and more compact, but they are substantially more expensive, making the prospect of buying one or two backup sets much less appealing.
The alkaline AA-size digital camera battery usually has a very short life - less than an hour in extreme cases - when used in a digital camera. This type of battery makes an acceptable emergency backup, especially if you are travelling with your camera. However, the Nickel Metal Hydride (NiMH) digital camera battery can be used instead of the alkaline ones with a charger and this rechargeable NiMH digital camera battery has a substantially longer life at an affordable price.
Another type of AA-size battery is the non-rechargeable Lithium batteries and rechargeable Nickel Cadmium (NiCD) batteries. The lithium digital camera battery has a superior life to alkaline AA's and offers good cold-weather performance but their price and non-rechargeable nature make them less useful than rechargeable NiMH batteries. It is also important to ensure that your camera can take a lithium digital camera battery. On the other hand the NiCD digital camera battery offers the advantage of retaining their charge while unused, unlike NiMH cells, but have shorter lives and need to be discharged completely before recharging which can be extremely inconvenient.
The LCD screen of a digital camera is responsible for consuming the most power from a digital camera battery so it is worth only using the LCD when necessary to help conserve the battery life. Always try to carry at least one backup set of batteries, especially if you plan on being away from power outlets for an extended period of time. The universally-available alkaline AA-size battery can make a convenient emergency backup if your regular digital camera battery fails.
