Digital Photography
Introduction
What is digital photography?
Digital photography is a form of photography that utilizes digital technology to make images of subjects. Until the advent of such technology, photography used photographic film to create images which could be made visible by photographic processing. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing. Using the information I have managed to gather from the internet and other sources I will present the history of digital photography, analyse digital camera and explain how to use it. I will also present advantages and disadvantages of using digital camera and explain some of the scientific terms in the glossary.

He used the pinhole in his darkened room to study the solar eclipse of 1544.
FIRST PERMANENT CAMERA PHOTOGRAPHS - 1825-26. Photographic history has recently been rewritten following the discovery of what is now considered to be the world's oldest photograph. The image, a reproduction of a 17th century Dutch print, predates by one year Frenchman Nicéphore Niépce's previous heliogravure of the view from his window at Le Gras, regarded until now as the earliest surviving photographic image.
In the early 1800s, Joseph Nicephore Niepce experimented with lithography at his home near Chalon, France. Nicephore explored light-sensitive varnishes, trying to find a coating that would record...
