All about Digital Cameras
by John Q. Harris

Capturing images without the need for film is the greatest advantage of the digital camera. Unlike the conventional camera, it does not rely on mechanical and chemical processes. You no longer have to send photos to a developing lab to have the pictures blown up or adjusted as long as you have a home computer. A series of ones and zeros is how all digital information is stored although the images are no different when viewed

These cameras still use lenses in much the same way that conventional cameras do. Instead of film the digital camera captures the light with the aid of a system which records the light rays digitally. A feature of the better quality versions is they have a sensor that converts light into electrical charges using a different system to their less expensive cousins. Some people believe the device used to capture an image in cheaper cameras the CMOS will eventually be the replacement for the better CCD but this is highly doubtful.

You may have noticed the price of some models has dropped, making them much more affordable to many people; the CMOS image capture device is the reason for this. 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. From the point of view on having good quality photos, search for a high megapixel version as it will be worth it for the image you will capture with it; if you are lucky you may find a model that is discounted because a new version is about to be introduced.

Better photos will be taken with a digital camera that has an optical zoom and not just a digital zoom; even a camera with a three times optical zoom is worth having. Rechargeable batteries are the best you can use with the NMIH versions able to be charged at anytime, even if they are not fully discharged; this will save money on batteries that are disposable. If it is possible, try to buy a model with many functions as you will be able to create some stunning effects; functions like those listed here for instance:

* Picture frame effects * Web cam function * Self timer

High resolution cameras require more space to store images so you will probably need an additional storage card. 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! Hopefully, these few tips will be enough to steer you in the right direction when you come to buy your camera. With all its technology, versatility and portability, the digital camera is the future of photography.
