A Simple Guide to 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.

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. The CCD and CMOS devices used in digital cameras capture light like tiny solar collectors both achieving the same effect but just by differing methods. Information to help you choose a suitable model of camera is mention in this review. 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.

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:

* Video capture * Time lapse (i.e. one shot every 5 minutes for example) * Self-timer

With large megapixel models, image storage is another issue to look out for and a storage card will be necessary. 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.
