mera, digital cameras store images on digital storage media instead of on film. The specifications of entry level digital cameras (digital cameras around USD1000 or less) are very limited. They have a film ISO(film speed rating) of about 80-100. This speed is very slow therefore a flash is needed indoors or in lower light conditions all of the time. The average resolution of a picture is about 480x600 or a 300, 000 pixels. Professional digital cameras, on the other hand, are very impressive. They have the features of a single lens reflex camera, or SLR. This gives a lot of control. The average resolution of images are about 3, 000, 000 pixels, quite similar to the resolution of film which is 18, 000, 000 pixels.

Unfortunately, there is a price to pay for all of this performance. Unless you are a serious and wealthy commercial photographer, USD 36, 000 is still a very heavy blow to your bank account. There are advantages of entry level digital cameras. For one thing, processing is cheap and fast. Processing takes at least and hour for film and costs about 3-4 dollars. This is excluding film. The processing of digital camera images takes around 20 minutes depending the speed of the communications port and the computer. There is no cost for film. Also, when images are needed on computer, you don't need to scan your images in. The images are already in digital format. This is very useful for real estate agents, newsletter photographers, Internet photos, advertising, insurance, and newspaper photographers because the resolution of the images is not a big issue in these applications. If you are willing to pay the price for professional digital cameras, you will not be disappointed. The image quality of professional digital photos meets the require...
