Of the digital photography equipment available on the market today, the digital camera has to be the most important single item for producing eye catching images. There has been a vast improvement in quality since the introduction of the first commercial digital cameras in the late nineteen eighties. This development radically changed the way images were captured and stored.
Originally, photographs were produced by allowing light focused from a lens to strike a cellulose film coated with chemicals. These chemicals reacted with the light to reproduce the scene in front of the lens which was then held on the film until it was processed. The film would then be passed through several chemical baths which would reveal the photograph and fix it permanently on the film.
This process has been reproduced electronically in the camera taking less time and does not require the use of chemicals. Film has been replaced with an array of sensors that are light sensitive and capture the scene in front of the lens the same way as a regular camera does. This image can then be transferred to a memory card in the camera after which it may be printed or displayed on a computer screen.
The modern camera needs to have removable memory fitted and a few popular formats are in widespread use such as the Compact Flash, SD card, Memory Stick and several other types that are not well known. Many of these memory cards are able to store hundreds of photographs in a variety of sizes quite unlike the small capacity cards used by earlier digital cameras.
Apart from the camera, no digital photographic process would be able to function without a computer. The computer enables the photos to be downloaded from the camera onto larger memory devices such as hard disk drives. Using a computer, the photograph can be manipulated to enhance sharpness, color tone and even to remove and add items that were not present in the original image.
Several types of digital cameras in use today use lenses that may be interchanged, offering the same flexibility of use as the film camera did. Although there are some slight differences in the way that digital cameras and film cameras operate, a tripod is often required to produce a pin sharp image and this should be a standard part of the digital photography equipment of any serious photographer.
