Capturing images without the need for film is the greatest advantage of the digital camera. The increased weight is because these cameras often use heavy batteries even though they have fewer moving parts. The storage used is similar to other computer based products so they are compatible with may other types of media we use to view images. 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.

Many similarities exist between the two types of camera because lenses are still required to capture light just the same as a film version. Using an electronic system, a lower specification digital camera does away with film although it is still capturing the light as with a traditional camera. There are two methods of achieving this; one is more expensive than the other and called a CCD or charge coupled device. Less expensive cameras us a complementary metal oxide semi-conductor or CMS device which does the same work of capturing an image and although some believe it could replace the CCD, this is not likely.

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. Although the images in a digital camera end up the same, the CCD and CMOS sensors capture light differently; the causal observer would probably never notice this difference though. When shopping for a camera of this type, you should take note of certain key features. Look for models with over 6 megapixels and you won't go far wrong as they will provide decent images; with the prices continually dropping, high resolution cameras are now more affordable.

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. Don't waste your money on standard disposable batteries as rechargeable ones these days are very affordable and long lasting which could save you hundreds of dollars on standard ones. Most models come equipped with some sophisticated software that can create interesting shots; below are just a few examples:

Video capture
Time lapse (i.e. one shot every 5 minutes for example)
Panoramic images

Most models these days can accept a storage card to accept more images because high megapixel models use up a great deal of memory. 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. So by doing this you won't feel as if you are a journalist or nature photographer wherever you go. These are just the basic things you have to look for in a camera when you buy one. The digital camera has reinvented photography for the masses and this is a trend that looks set to continue.
