In this article, I shall provide a list of the digital camera key features that you should think and know about. Here’s a summary of what to look for:
1.Resolution
Resolution determines how sharp your image will be, how much you can enlarge a photo before the pixels start to becomedistracting, and how much you can crop a photo and still be left with adecent image that you can enlarge and manipulate.
2.Lens
The lens is the eye of your digital camera. Look for the following in your lens:
•You’ll want good-quality optics that focus a sharp image on yourcamera’s solid-state sensor. The best way to gauge the quality of the lens is to take a test photo or two. A vendor’s reputation or lab tests in magazines are other ways to evaluate a lens.
•The lens also needs enough light-gathering power to let you shoot inreduced light levels. A camera’s light-gathering capabilities are measured in something called f-stops.
•The magnification power of the lens (how large or small an image appears to be from a particular shooting position) is another factor. A digital camera’s lens magnification can usually be varied by zooming in and out to make the image larger or smaller.
•A related factor, the zoom range, is another key characteristic to look at. Where magnification tells you only how large or small theimage can be made to appear, the zoom range tells you the differencebetween the two. As I mention under the discussion of generalcamera categories, some lenses have only a small zoom range, say 2:1,whereas others have a longer range, up to 12:1 or more (which meansthe image size can be varied up to 12X).
What’s the difference between magnification and zoom range?
Magnification deals purely with how large or small an image appears to sbe. For example, one lens may extend from a 28mm (35mm equivalent)to 85mm (35mm equivalent) magnifications, a 3:1 zoom range. Another lens might go from 35mm to 105mm (both 35mm equivalents) and also qualify as a 3:1 zoom range optic. However, the second lens would provide more relative magnification.
3.Storage
The kind and amount of removable storage is another key feature. The more storage space you have for photos, the more pictures you can take before “reloading” your digital camera. Most cameras use CompactFlash, Secure Digital, or other electronic “film” media.
4.Exposure controls:
Except for the least expensive models, all digital cameras include automatic exposure controls that adjust the amount oflight reaching the sensor based on the lighting conditions of your subject. If the illumination is low, an auto exposure system uses a wider lens f-stop or exposes the sensor for a longer period of time. If there is a lot oflight, the exposure system reduces the amount of light reaching the sensor. Cameras with more versatile automatic exposure controls let you specify what type of exposure to use. For example, when shooting action, it’s often preferable to use the shortest shutter speed possible to freeze the motion and to adjust the size ofthe lens opening instead. Conversely, if you want a lot of your image to be in sharp focus (say, objects very close to the camera and very far are both important), you may be able to choose an exposure mode that favors maximum depth of field. You probably want a digital camera that can handle several different exposure modes and lets you set exposure yourself.
5.Focus controls
Most digital cameras also have an automated system for sharply focusing your images. Some are more versatile than others, and many cameras also let you focus manually to ensure that the subject matter you want to emphasize is the sharpest.
6.Viewfinders
Digital cameras generally have four ways to let you preview and compose your images prior to exposure. The color LCD panel on the back of the camera shows you the same image that the sensor is capturing. The LCD is often hard to view in bright light, so digital cameras also may have optical viewfinders that let you see a non electronic version ofthe frame. More-advanced cameras might include a second LCD (EVF) in the camera, where it is shielded from the glare of the surrounding light. Single lens reflexes (SLRs) let you see an optical version of the picture through the same lens used to take the photo.
7.Other equipment, other features
Finally, as you choose your digital photography gear, think about accessories, such as tripods, filters,add-on lenses, external electronic flash units, scanners, printers, and additional stuff. Even the storage media you use to archive your photos, such as CDs or DVDs, can all be important.

Canon Digital Camera Tips
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.

What Are The Different Battery Types Of Digital Camera?
One of the most important accessories of a digital camera is perhaps its batteries. There are some digital cameras where battery life is quite limited and drains with a couple of shooting hours. However, there are digital cameras that are famous for their battery life simply goes on. Therefore, it is important to know your methods of using the camera that you can then lean on the battery type you need for your camera.
There are basically two types of digital camera batteries. One is the standard AA and the other is rechargeable. The latter is also known as a battery of property, and that made by the same manufacturer.
A type of ownership of the battery is comparatively more expensive, lighter and more tight and compact. The cost makes the purchase of one or two backups a bit prohibitive.
The standard AA-size alkaline batteries usually have a short life - sometimes even less than an hour when using a digital camera. These batteries make good backups, especially if you are traveling. A better choice is to use nickel metal hydride (NiMH) digital camera with a charger. This option rechargeable have a longer life and comes at an affordable price.
The other two types of AA batteries are lithium batteries, which can not recharge the battery and nickel cadmium (NiCd). Lithium batteries digital camera batteries last longer than alkaline simple and perform well in cold weather. However, their prices and non-enforceability would reduce the attractiveness compared to NiMH batteries. It is important to ensure that your digital camera can charge a lithium battery. The advantage of a NiCd battery is that it can hold charge when not in use, while the disadvantage is that the battery needs to be fully discharged before recharging. This can be very cumbersome and inconvenient.
If you want to conserve battery life, it is prudent to make judicious use of the LCD screen of your digital camera, this element s maximum power consumption when in use.
If you are going to stay away from a power source for a long time, it is always advisable to take at least a backup. The standard alkaline AA battery is sufficient for this purpose, in case your usual digital camera battery packs.

A Guide to Disposable Digital Cameras
Disposable Cameras (also called single-use cameras) first in the market as film cameras. You should take the entire camera back where you bought it and opens it, takes the film and the process, resulting in photos that were virtually indistinguishable from photos taken with a more conventional camera. Now, following the trends in conventional cameras, there is a choice between using film or digital disposable cameras.
Some people think that digital cameras are too hard to use, disposable digital cameras offer a solution. Disposable digital cameras have all the great features that attract people to digital cameras such viewing your pictures before printing and photo manipulation. With a disposable digital camera, you get a flash, a timer, and a viewing monitor (depending on model you buy). This means that you can see if you want to take the picture over or not, as you also have the ability to delete an unwanted photo, and retake if you have the opportunity. In addition, a free picture CD is usually included with your prints in a disposable digital camera package.
Have a disposable digital cameras offer the same features as a normal digital camera? It offers the features most frequently used, but will not expand or night shots, or most of the other bells and whistles that come with a $ 400.00 camera. But disposable digital cameras do not cost about $ 400, and allow you to leave your cameras in a reliable place at home and still have the technology that may crave a camera for between $ 10.00 and $ 20.00, and sometimes even cheap.
However, you can connect the disposable digital camera to your PC or Mac Photographs must be developed at a store that provides the right equipment for your particular brand of disposable digital camera. In fact, this may be a plus for the technologically challenged, however, since it does not connect the cable, crop, correct color - no need to waste hours in front of a computer, as does everything for you. Your time is valuable

Digital cameras explained
Over the last few years, the picture quality in digital cameras has becoming amazing. As recently as the year 2000, even the very best digital cameras you could buy produced grainy, poor-quality images that could never compare to what film had to offer. Today, though, digital cameras can easily rival and even exceed the quality of film, capturing pin-sharp digital images and never needing to be refilled with anything except power.
When you buy a digital camera, the most important thing you should look for is how many mega pixels (million pixels in the image) the photos it takes are. Cameras available today range from about 3MP at the low end to 10MP or more at the high end, with the price increasing steadily with each extra mega pixel.
However, how many mega pixels the camera has is not the only thing you should consider. Battery life is very important, as cameras with a short battery life can be frustratingly unusable, and the presence of various features in the camera’s software like auto focus and digital zoom should also be a consideration, as well as the camera’s ability to record non-photographic material like sound and video.
Ultimately, the best thing to do with digital cameras is to either buy the cheapest one you can find or a very high-end one – if you go for something mediocre, you will just be frustrated at having paid a lot of money for a camera that isn’t really all that great. If you are choosing between two cameras at a certain price point, it is almost always better to buy the one made by a known brand, as they will tend to have much better build quality, software and battery life, as well as being generally better-designed and easier to use.
As a final note, if you just want a cheap digital camera to take around with you and take occasional snaps of your friends and places you go, it’s well worth considering getting a mobile phone with a digital camera built in. As you take your phone around with you anyway, it’s no extra hassle to carry a camera phone, and the pictures they can take are rapidly increasing in quality, to the point where they are now where digital cameras were only a few years ago. As technology gets even better, a camera phone is increasingly becoming a very smart alternative to a digital camera for the casual user.

5 Ways To Earn Money With Digital Cameras & Photo Printers
When it comes to the internet and the advancements of modern technology, the revenue generating options are truly unlimited. One way that many people are finding great success as entrepreneurs is through the use of their digital cameras and photo printers. Whether you use your digital knowledge to enter photo contests using images taken with your digital camera or choose to start an online auction business, the use of a both camera and photo printer are essential.
With entrepreneurship in mind, the following five tips may help to get you started on the road to success using nothing more than your digital camera and photo printer.
$Start an eBay business and use your digital camera to take pictures for inclusion in your auctions. If a picture is worth a thousand words, how much money will it be worth for your auction? After all, would you buy something without seeing it?
$Become an amateur photographer using your digital camera and print out the images using a realistic photo printer, which can use either black or color ink.
$Create personalized calendars by taking a photo with your digital camera, incorporating it into a calendar creation program and print them out using a photo printer. These are extremely popular at craft shows and flea markets.
$Take photos using your digital camera and incorporate them into a program that manipulates photos. You can even take two photos and merge them together. For instance, take a photo of two sunflowers and another of your two best friends. Download the images from your digital camera onto the computer and manipulate them so that the faces of your two best friends are inside of the sunflowers. Print this photo using your photo printer and use it as an example of your new digital imagery business. These, too, are extremely popular at craft shows.
$Using nothing more than a digital camera and quality photo printer, you can work in the publishing industry. Several years ago, a national magazine cover featuring a well-known celebrity was created with nothing more than a personal photo printer. The magazine office was unable to make an e-mailed image work, so they enlisted the help of a writer who enlarged the photo and printed it out using a color photo printer. The print was then mailed to the magazine’s office, who then used the image as their full-color cover picture.
When purchasing any type of electronics, including digital cameras and photo printers, always pay close attention to the warranty and make sure that you are buying a quality name in technology. Depending on your intended use, you may want to select a digital camera with a high pixel count and a photo printer capable of producing high DPI (dots per inch) images. Both will allow for better quality and more realistic photo creations.
