Our love of digital cameras seems to be because the results are instant as film is no longer required to be processed. With numerous functions they do not need the complicated mechanical components of a standard film camera. The images are stored in a format that can be read by most modern printers, computers and even mobile phones for example. 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. 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. Up market versions us a different system again with a charged couple device, or CCD, being the capture system which transfers the light into an electrical signal. 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.
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. It would take an experienced digital camera enthusiast to see the difference between an images captured with a CMOS against the superior CCD system. There is no need to feel confused by the range and functions these cameras have if you are armed with a few basic facts which are provided in this article. 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megapixel version as it will be worth it for the image you will capture with it; you may find a model that is being superseded shortly - available at a discount.
Unless your budget just won't stretch that far, don't buy a digital camera with only a digital zoom or you will find pictures that aren't very clear when you print them; it is much easier to take exactly the image you want with an optical zoom. Rechargeable batteries can be charged up to a thousand times and save money, do you need any other advice for why they are best? Most models come equipped with some sophisticated software that can create interesting shots; just like some of these here:
Picture frame effects
B/W image conversion
Image editing
If you're a photo freak, be sure that you have enough memory to take plenty of shots without worrying about storage. Digital storage has come down in price so buying gigabyte card will no longer require a loan but you shouldn't think of having anything less than this.
Unless you intend to use your camera for serious photography there isn't any need for a bulky very high specification version. Professional photographers may need heavy, bulky equipment but there is no requirement for a keen amateur to do so! I hope these few tips will help you choose a camera you enjoy using for a long time. The future of photography has moved on and digital cameras are that future with almost everyone carrying around one type or another every day!
