Digital Cameras 

Basically a digital camera allows you to capture pictures without the use of films. Unlike the conventional camera, digital cameras do not rely on mechanical and chemical processes.  They have a built in computer and record the images that are captured in an electronic format.  

Since the images that a digital camera captures are in electronic form, these are recognized by computers. This format is referred to as pixels, which are tiny colored dots represented by ones and zeros that make up the pictures taken. Just like any conventional cameras, a digital camera has a series of lenses that focus the light and creates the image that you want to capture.

The price of a digital camera has been coming down for a while now.  The main reason for this is because of the introduction of CMOS image sensors, which are less expensive and are easier to manufacture than CCD sensors.

When shopping for the best digital camera, take note of these key features.

Image quality. Check the resolution of the camera. The higher the resolution, the more you will be able to enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid.

Lens. Choose a digital camera with better digital zoom. The digital zoom of the camera will enable you take the pixels from the image sensor and incorporate them to make an image.

Power. Always opt for rechargeable batteries, they can always come in handy, plus you don’t waste as much money on the disposable ones.

Memory.  If you enjoy taking lots of photos, be sure that you have enough memory in your camera

Computer Interface. Always make sure that it is compatible with your PC, laptop, palmtop or whatever your local picture printer software is.

Physical. If you are going to be carrying it everywhere, choose a handy and portable digital camera. This way, it won’t always feel as heavy and bulky as those cameras that you see professional photographers dragging around.

These are just the basic things you have to look for in a digital camera when you buy one. A digital camera is so great that it is quickly replacing all conventional cameras in the market, with all its technology and portability, truly the digital camera is the future of cameras.
