Using a mosaic photosensor, Eugene F. Lally of the Jet Propulsion Laboratory first showed how still photos could be produced in a digital domain. An engineer at Eastman Kodak, Steve Sasson, used solid-state CCD chips to build a prototype digital camera having a resolution of 0.01 megapixel, and recorded black and white digital images to a magnetic cassette tape. With this prototype model, Steve took the first image in December of 1975 taking 23 seconds to capture it.

In 1988, Fuji DS-1P became the first digital camera that captured images as a computerized file. However, the camera never entered the U.S. market.

The important task is to put through a sieve all the hype and get the best digital camera suiting your needs.

But before you start comparing the features of different cameras, it is important for you to make certain basic decisions. They are related to identifying your basic needs and prerequisites for the camera. Decide on why you need a digital camera. The purpose should be well-defined. Ask yourself, is it for taking candid snapshots or for serious photography. If you are buying the camera for clicking pictures for an exhibition or a photo website, the criterion of purchase will definitely change. There are different sizes of models that include compact, miniature and big size cameras. Be clear about the size you need to buy.

Then you may start comparing the specific features of the digital camera. You can compare the quantity and quality of the pixel. The more the pixels in the camera, the clearer and quality pictures it would produce. The pixels are nothing but tiny squares of color and light. Thus to get the best camera, you should have the best pixel quality. The sensor of the camera can be called as its eye. Generally, the digital cameras with larger sensors have better quality diodes, which result in sharp and clear pictures.

You should also compare the digital camera on the grounds of its memory. All the digital photographs require the storage capacity of several megabytes. You should compare the capacity of built-in memory of the digital camera. You should certainly go for the one with more battery capacity.
