For those of you who are unsure exactly what a digital camera is, it is a device that can capture images without having to use film. Storing the information as digital-bytes is how this type of camera keeps the pictures you have taken, safe and ready to view, store or print! With the upsurge of home computers it means that almost anyone can store and then play with the images on their own pc. This computer language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just captured.

Focusing light through a lens onto a suitable receptive surface is still common to both types of camera. Instead of film the digital camera captures the light with the aid of a system which records the light rays digitally. A charge couple device is the light capturing device in the quality models that is used to convert light into electrical signals and as far as the user is concerned, an image is saved just like an ordinary device. 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. 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. 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. 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and the higher the resolution the more you will be able to enlarge your picture; you may find a model that is being superseded shortly – available at a discount.

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; optical zooms can produce some interesting effects. 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. Most models come equipped with some sophisticated software that can create interesting shots; just like some of these here:

High resolution cameras require more space to store images so you will probably need an additional storage card. If you are a keen photographer then you will need a larger size storage card if you don’t want to run out of space after a hundred shots so look for cards over 1GB.

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. There is no longer any need (even for keen amateur photographers) to carry around large, heavy models if you don’t have to. I trust the brief information that has been supplied here will help you with your choice of camera. The digital camera has reinvented photography for the masses and this is a trend that looks set to continue.
