Basically a digital camera is a device use to capture pictures without the use of film. Unlike the conventional camera, it does not rely on mechanical and chemical processes. The images are stored in a format that can be read by most modern printers, computers and even mobile phones for example. The term used for how these images are stored is called pixels; a series of dots using one's and zero's in the same way that a computer stores information.
Strangely, both types of camera focus light onto a surface that captures an image using a set of lenses. Instead of film the digital camera captures the light with the aid of a system which records the light rays digitally. Images seen on good and more expensive models are captured using an alternative method of a charged coupled device commonly known as a CCD which you may have heard of. 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.
In order to bring digital photography to the masses, the price had to come down; an expensive part of the system is the capture device, so by replacing the CCD with the CMOS device it enabled the price to be reduced. 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. Some useful tips are mentioned here if you are currently looking for a camera like this. Image quality is important or it will be waste of time taking them so look for the highest megapixel model within your price range; with the prices continually dropping, high resolution cameras are now more affordable.
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. Although it shouldn't be a problem, opt for rechargeable batteries as they can always come in handy and you don't waste as much money on the disposable ones. If you want to do more than just take snap shots, look for a model that is high on functionality to create stunning photos you can be proud of; just a few examples of functions to look for are shown here:
- Video capture
- Multiple exposures (on a single image)
- Negative image
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.
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! I trust the brief information that has been supplied here will help you with your choice of camera. With all its technology, versatility and portability, the digital camera is the future of photography.
