High Technology in our hands

The instant results seen with a digital camera has revitalized the whole photographic industry. Unlike the conventional camera, it does not rely on mechanical and chemical processes. Of course, because the images are digital, it means that they can be stored, filed and manipulated using a computer or specialized printer. 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.

Strangely, both types of camera focus light onto a surface that captures an image using a set of lenses. The difference between the two is a conventional camera focuses its light on a film while a digital camera focuses the light onto a device that electronically records the light. 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.

CCD’s are much more costly to produce than the CMOS devices, but by using the latter it has brought the cost of many models down considerably. 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. When shopping for a camera of this type, you should take note of certain key features. Image quality is the all important factor and the higher the resolution the more you will be able to enlarge your picture; you may find a model that is being superseded shortly – available at a discount.

Better photos will be taken with a digital camera that has an optical zoom and not just a digital zoom; perhaps you can remember how grainy and blurred images become when you used your camcorder’s digital zoom function? 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. 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:

• Sepia shots


• Time lapse (i.e. one shot every 5 minutes for example)


• Self timer

If you’re a photo freak, be sure that you have enough memory to take plenty of shots without worrying about storage. Think 1GB as a bare minimum with today’s high resolution models so if you’re a photo junkie you can takes pictures of just about anything.

If you are going to be taking your camera everywhere, choose a handy and portable model. There is no longer any need (even for keen amateur photographers) to carry around large, heavy models if you don’t have to. By using this information you shouldn’t go to far wrong when you go to buy your camera. Digital cameras are here to stay but expect even greater advancements in the future.
