I have posted a lot of reviews of digital cameras but have now found a great buyers guide to digital Cameras as well. When you are out there shopping everyone tries to balance megapixels, sharpness, modes, scene settings, shutter response time, and of course price. There are a ton of companies offering Digital Cameras from Kodak, Canon, Panasonic, FujiFilm, Nikon and a ton more. Here is a great article from Content Articles and Olga Sen that covers the cameras in depth
With the advent of modern scientific tools, life has become highly sophisticated. One of the fine examples of evolution is the advent and craze for digital cameras. A digital camera is equipped with an electronic photosensitive sensor. The photographs are stored digitally in the in-built memory of the camera or onto a memory card and can be uploaded on a computer for viewing emailing or printing. There is no need for buying films or getting them processed with these modern gadgets.
The current demand for cameras can be traced back to the 16th century, although modern film cameras did not really exist until the late 1800’s people have used the cameras to capture the history or larger-than-life-events. As the science has expanded in this ever-shrinking world, the expansion of camera technology has soared to new heights. From the normal camera, the world has stepped into the era of digital cameras. These cameras have brought in a complete revolution in the camera industry.
The features of digital camera are so unique and advanced, that handling the camera has become a child’s play. Before you go and buy your digital camera, you should know some basic information on these modern weapons. You must pick the right camera to capture your precious moments.

How a Digital Camera Works
The basic difference between a digital camera and normal camera is that a normal camera uses a film to store the photographic images, while a digital camera uses an in-built memory to store the photographs in digital format. The lens of the digital camera focuses the light directly on to a semiconductor device. This device records the light electronically. The computer then breaks and stores this electronic data into digital data, which gets stored in the memory of the camera and can be transferred on to a computer.
Charge Coupled Device (CCD) is employed as the image sensors in the digital cameras. These charge coupled devices are responsible for converting the light into electronic forms. The CCD is made up of light sensitive diodes which accumulate electrons when hit by a beam of light. The prominently used CCDs are the triple CCD cameras. The product of these cameras is superb as the three CCDs react separately to the three basic colors such as red, blue and green. The end result is fantastic. These electronic symbols are then stored as digital data in the digital camera.
Buying a Digital Camera
The modern market is booming with various types of digital cameras. Digital cameras vary in function and most of all their mega pixel quality. If you plan to buy a digital camera, prior information about digital cameras would be an added advantage.
First of all you should figure out your need for buying a digital camera. The need for a digital camera helps you narrow your search for the best camera, suited to your requirements. You might want to buy a digital camera for posting photographs on the net, using photos for professional graphics work, to get a better-quality photographs and much more.
Next thing you should determine is the resolution you require in a digital camera. There are broadly 5 classifications of resolutions for digital cameras. These resolutions are expressed as mega-pixels. The higher the resolution of a camera, the better quality photograph it will produce. There are cameras available with 6 and 7 mega-pixels however, anything above 4 mega-pixels will produce really great photos.
