Fundamentally a digital camera is a device used to capture photos without the usage of film. Not like the conventional camera, the electronic camera doesn't depend on mechanical and chemical processes. It has a built in PC and records the photographs it captures in an electronic form.

Since the photographs that a digicam captures is in electronic form, it's a language recognized by PCs. This language is known as pixels, tiny coloured dots represented by ones and zeros that make up the picture that you took. Just like any conventional cameras, a digital camera is furnished with a sequence of lenses that focus the light and creates the image that you wish 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 gadget which electronically records the light. Remember the built in computer, it comes in here and breaks this info to digital info ensuing to all of the features of the electronic camera.

Another feature of the digital camera is that it has a sensor that converts light into electric charges. A charge coupled device or CCD is an image sensor that is found in a digicam. 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 don't accept that it can replace the CCD for top end digicams.

A collection of miniscule diodes, the CCD gathers electrons when they are struck by photons or the light particles. Each diode or photosite is sensitive to light, suggesting that the brighter the light, the amount of the electrons gathering will be bigger

The price of an electronic camera today have been depreciating, one of the most important reasons of this is because of the advent of CMOS image sensors, this is due to the fact that CMOS sensors are cheaper and are easier to turn out than CCD sensors. Nikon digital camera prices are the cheapest. A CCD and CMOS sensor works the same way at first, by changing the light electrical charges into photosites. Simply placing it, is to suspect that an electronic camera works in such a manner as thinking that the uncountable millions of tiny photovoltaic power cells, every one of which forms a part of the whole image. Both CCD and CMOS do this job using different techniques.

When out shopping for the best digicam, pay attention to these important 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 coarse or the out-of-focus effect that we all wish to avoid.

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

Power. Always select rechargeable batteries, it's often possible to turn out to be handy, and you do not waste as much money on the dispensable ones.

Options. So you can gloat to your pals how good a photographer or artist you are. Or choose the one that gives options that best deal with your lifestyle, so you will not ever whine how you never get the right pictures.

Memory. If you're a photo freak, be absolutely sure that you have enough memory in your camera to take all the wacky, weird, funny and nearly any photo your are able to. Think 512MB if you are a photo addict and takes photos of pretty much anything.

PC Interface. Always make sure that it is compatible with your PERSONAL COMPUTER, laptop PC, palmtop or whatever your local picture printer software is, you don't want to go running round the entire state or the country looking for a computer that is compatible with your digicam, wont you? !

Physical. If you're going to be bringing it everywhere, choose a handy and portable digicam. This way, it won't always feel as heavy and awkward as those cameras that you see pro photographers are always pulling on their neck. Don’t they ever become bored with that? !

These are just the fundamental things you have to look for in a digital camera when you purchase one. A digicam is so great it's quickly replacing all standard cameras in the market, with all its technology and portability, actually the digital camera is the future of cameras.
