Because people no longer have to wait for film to be processed and returned, the digital camera market continues to grow. The lack of mechanical parts has meant that the size of these cameras is only dictated by the size of battery needed to power them. As the captured pictures are stored in digital form, almost every computer and other electronic viewing and printing device can read them too. This computer language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just captured.

Strangely, both types of camera focus light onto a surface that captures an image using a set of lenses. Using an electronic system, a lower specification digital camera does away with film although it is still capturing the light as with a traditional camera. Images seen on good and more expensive models are captured using an alternative method of a charged coupled device commonly known as a CCD which you may have heard of. Images captured in what are considered to be the low-end cameras are using a CMOS device which competes directly with the CCD of the high-end variants.

By using the CMOS sensor, many models have become more affordable for those users that do not require such a high performance device. A digital camera works where 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. Information to help you choose a suitable model of camera is mention in this review. Look for models with over 6 megapixels and you won’t go far wrong as they will provide decent images; with the prices continually dropping, high resolution cameras are now more affordable.

Always choose a digital camera with an optical zoom as this will enable you take pictures without any distortion; optical zooms can produce some interesting effects. Today’s nickel metal hydride rechargeable batteries are very powerful and last for around a 1,000 charges so always use these if you want to save money. Many people are just happy to point and shoot but if you want to do a little more then try to buy one with more functions; examples are listed below:

<ul> <li>Video capture</li> <li>Continuous shooting</li> <li>Image editing</li> </ul>

You will also need something to store the captured images on especially with the high megapixel models available today. If you are a keen photographer then you will need a larger size storage card if you don’t want to run out of space after a hundred shots so look for cards over 1GB.

Cameras are now very tiny compared to a few years ago so you can actually carry around a high specification variant in your pocket and still be able to take fantastic pictures. These smaller models are very discreet and don’t make you feel as if you are on a photographic safari but you can still take professional looking pictures. I trust the brief information that has been supplied here will help you with your choice of camera. The digital camera has reinvented photography for the masses and this is a trend that looks set to continue.
