Digital Cameras: The New Generation
by Olga Sen
With the advent of modern scientific tools, life has become highly
sophisticated. There has been a significant evolution in the technology and the
lifestyles of the human beings. 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 and can be directly uploaded on a computer for
viewing and printing. There is no need for buying films or getting them
processed with these modern gadgets.
The craze for using the cameras can be traced back to the 16th century. Man has
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.
Now buying a digital camera should be easy!
