Basically a digital camera is a deice use to capture images without using film. Unlike the conventional camera, the camera does not rely on mechanical and chemical processes. It has a built-in computer and records the images it captures in electronic form. The driver and one does not even require the use of electricity.

Since the images taken with digital cameras in electronic format, is the language of computers are known.

This language is called pixels, the small colored dots represented by ones and zeros that make up the picture you just took. Just like a normal camera, digital camera is equipped with various lenses that focus the light and creates an image that you want to capture. The difference is here, then, a traditional film camera focuses the light, while a digital camera focuses light to the semiconductor component, the electronic data of light. Remember-built computer, is here and break this information into digital format, which makes all the characteristics of a digital camera.

Another feature is that the digital camera is a sensor that converts light into electric charges. Charge Coupled Device or CCD image sensor, which is located in a digital camera. Although other low-end digital camera use complementary metal oxide semiconductor or CMOS as an image device, but can become better and more famous in the future, but most engineers do not believe it can replace the CCD the higher-end digital cameras.
A collection of tiny diodes, the CCD gathers electrons when struck by photons or light particles. Each diode or photosite is sensitive to light, which means that the brighter the light, the number of the collection of electrons will be higher

The price for a digital camera today has been declining, a major cause of this is due to the introduction of CMOS image sensors, it is because CMOS sensors are cheaper and easier to manufacture than CCD sensors. A CCD and CMOS sensor works the same way as a first step, converting light into electric charges photo sites. In other words, it is probable that a digital camera works in such a way, to think that the millions of tiny solar cells, each of which constitutes a part of the whole picture. Both CCD and CMOS do this task using different methods.

When you shop for the best digital camera, consider these important functions.

Image quality. Check the resolution of the camera. The higher the resolution, the more will be able to enlarge your photos without grain or off the effect of development that we all want to avoid.

Lens. Choosing a digital camera with better digital zoom. Zoom digital camera lets you take your pixel image sensor and incorporate them to make a picture.

Power. Always use rechargeable batteries, they can still be used, the more you do not lose much money on disposable lighters.

Opportunities. So you can brag to your friends how good a photographer or an artist you are. Or choose one that gives options that best suit your lifestyle so you'll never whine that you never get the right images.
Memory. If you are a photo freak, be sure you have enough memory, the camera captures all the fun, strange, funny and almost all of your photo. Think of the 512 if you're a junkie pictures and take pictures of anything.

Computer interface. Always make sure it is compatible with your PC, laptop, handheld or any other software on the local printer image not want to go to run across the state or country in search of a computer is compatible with your camera digital, you not!

Physics. Are you going to put it everywhere, choose a camera handy and portable digital. In this way, it always feels heavy and bulky cameras that see professional photographers are always dragging on the neck. Do not get tired of that?

These are basic things you should 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, a real digital camera is the future of the cameras.
