With no longer any need for film, digital cameras have started a whole new era for photography. Unlike the conventional camera, it does not rely on mechanical and chemical processes. Since the images captured are in electronic form, this is a language recognized by computers. Images are stored in digital form using the term Pixels which is just a digital expression of images that are made up of ones and zeros. Focusing light through a lens onto a suitable receptive surface is still common to both types of camera. However, it is how the digital camera captures the light that makes all the difference because it achieves this by using a special sensor as opposed to film. There are two methods of achieving this; one is more expensive than the other and called a CCD or charge coupled device. The CMOS device is used in cheaper cameras and does the same work as a CCD but it is doubtful that this system will replace those devices in the quality models. The price has been depreciating recently and one of the main reasons for this is the introduction of CMOS image sensors; because CMOS sensors are less expensive and are easier to manufacture than CCD sensors. Whilst both the CMOS and CCD systems both capture an image using millions of solar cells to make up the whole picture, they perform this in slightly different ways Information to help you choose a suitable model of camera is mention in this review. Image quality is important or it will be waste of time taking them so look for the highest megapixel model within your price range; the higher the resolution of the camera the bigger the photos that can be printed. Many people rave about a digital cameras zoom power but the image is being artificially magnified so always try for an optical zoom even if it is one with only a low magnifying power; perhaps you can remember how grainy and blurred images become when you used your camcorder's digital zoom function? Rechargeable batteries can be charged up to a thousand times and save money, do you need any other advice for why they are best? If it is possible, try to buy a model with many functions as you will be able to create some stunning effects; examples are listed below: Video capture Web cam function Negative image If you're a photo freak, be sure that you have enough memory to take plenty of shots without worrying about storage. Although larger storage cards have plummeted in price, a 1GB card should be enough for most peoples needs; some cameras won't accept very high capacity cards anyway. 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. Professional photographers may need heavy, bulky equipment but there is no requirement for a keen amateur to do so! There has only been room for a few basic hints and tips here but they should help with your choice of camera. The digital camera has reinvented photography for the masses and this is a trend that looks set to continue.
