Digital Cameras: we can't live without them by Francisco Segura
Our love of digital cameras seems to be because the results are instant as film is no longer required to be processed. Unlike the conventional camera, it does not rely on mechanical and chemical processes. A great advantage over the older film system is how easily the images can be stored using a computer or other mass storage device. Whilst the image storage may be digital, the end result looks no different from a picture printed from photographic film.
These cameras still use lenses in much the same way that conventional cameras do. All the budding digital camera enthusiast needs to know is that despite the difference in how the image is captured, the ultimate effect is the same. 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.
The CMOS device is this reason that many models have come down in price so much as they are easier and cheaper to produce than their CCD cousins. 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. 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. Other than budget, your main concern should be resolution and what that means is the higher the resolution or megapixels you can afford the better the pictures will be; they can also provide prints that are larger without any degradation.
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; even a camera with a three times optical zoom is worth having. Rechargeable batteries can be charged up to a thousand times and save money, do you need any other advice for why they are best? Although most are supplied with a number of photo functions, try for as many as you can because you will appreciate the effects that can be achieved; functions like those listed here for instance:
<ul> <li>Macro (close up shots)</li> <li>Time lapse (i.e. one shot every 5 minutes for example)</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. 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. So by doing this you won't feel as if you are a journalist or nature photographer wherever you go. 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.
