Digital Photography
* Merits and Demerits of Digital technology in still photography.
Digital Technology:
A digital system is a technology that uses discrete, discontinuous representations of information or works in a discontinuous manner. This is contrasted with continuous, or analog systems which behave in a continuous manner, or represent information using a continuous function.
Although digital representations are discrete, the information represented can be either discrete, such as numbers and letters or continuous, such as sounds, images, and other measurements.
The history of modern digital technology can be traced back to the work on semiconductors--the materials of choice for computer chips--by Michael Faraday in the late nineteenth century. It was not until 1971, however, that IBM sowed the seeds for a revolution in personal computing with its PC 5150 business computer. By 2000, the semiconductor industry worldwide was worth $200 billion.
Unlike analog voltage or current signals, digital signals do not vary smoothly and continuously, but rather in steps or increments. Digital technology generates, stores and processes data as a string of binary digits, or "bits"--ones and zeroes--and its role in society since the early 1990s has been compared to that of the railroad during the Industrial Revolution.
Digital Photography Technology:
Digital Photography Technology has taken over the world. Everyone wants a digital camera. The advantages of Digital Photography Technology are phenomenal. You have the ability with a digital camera to take a picture and immediately look at the finished image, so it can then be sent it anywhere in the world within minutes or make a print. That is something that was not even considered just a few years ago.
There is no reason why any person can not take a good picture with the wide range of digital cameras that are available. Cameras for Digital Photography Technology are available in a price range starting from one hundred to thousands
