					DIGITAL CAMERA: THE FUTURE OF CAMERAS

Basically a digital camera is a deice use to capture pictures without the use of films.
Unlike the conventional camera, the digital camera does not rely on mechanical and
chemical processes. It has a built in computer and records the images it captures in an
electronic form. Having and operating one does not even require the use of electricity.

Since the images that a digital camera captures is in electronic form, it is a language
recognized by computers. This language is called pixels, tiny colored dots represented
by ones and zeros that make up the picture that you just took. Just like any
conventional cameras, a digital camera is furnished with a series of lenses that focus
the light and creates the image that you want to capture. The difference here is then; a
conventional camera focuses its light on a film while a digital camera focuses the
light into a semiconductor device that electronically records the light. Remember the
built in computer, it comes in here and breaks this information to digital data resulting
to all the features of the digital camera.

Another feature of the digital camera is that it has a sensor that converts light into
electrical charges. A charge coupled device or CCD is an image sensor that is found
in a digital camera. While other low-end digital camera use complementary metal
oxide semiconductor or CMOS as an image device, it can still become better and
more famous in the future but most engineers are do not believe that it can replace the
CCD for higher-end digital cameras.

A collection of tiny diodes, the CCD gathers electrons when they are struck by
photons or the light particles. Each diode or photosite is sensitive to light, meaning
that the brighter the light, the number of the electrons gathering will be larger

The price of a digital camera nowadays have been depreciating, one of the main
reasons of this is because of the introduction of CMOS image sensors, this is because
CMOS sensors are less expensive and are easier to manufacture than CCD sensors. A
CCD and CMOS sensor works the same way at first, by converting the light electrical
charges into photosites. Simply putting it, is to think that a digital camera works in
such a way as thinking that the millions of tiny solar cells, each of which forms a part
of the whole image. Both CCD and CMOS do this task using different methods.

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 thou 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 dont waste as much money on the disposable ones.

Options. So you can brag to your friends how good a photographer or artist you are.
Or choose the one that gives options that best cater to your lifestyle, so you wont ever
whine how you never get the right pictures.

Memory. If youre a photo freak, be sure that you have enough memory in your
camera to take all the wacky, freaky, funny and just about any photo you can. Think
512MB if youre a photo junkie and takes pictures of just about anything.

Computer Interface. Always make sure that it is compatible with your PC, laptop,
palmtop or whatever your local picture printer software is, you dont want to go
running around the whole state or the country looking for a computer thats
compatible with your digital camera, wont you?!

Physical. If you are going to be bringing it everywhere, choose a handy and portable
digital camera. This way, it wont always feel as heavy and bulky as those cameras
that you see professional photographers are always dragging on their neck. Dont they
ever get tired of that?!

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.
