Digital imaging can be defined many different ways. I would like to submit that digital imaging is electronic transmission of information that has been encoded digitally and enhanced by technology that transmits information in a digital form. (As for storage and processing by computers) New digital imagery techniques have changed the way we view the world.
It gives us the ability to go places without ever leaving the comfort of our own homes. I believe that a revolution is taking place in the way people learn and the way instruction is given.

In the late 20th century, the techniques used in creating effects entered a new era, that of digitization. In digitization, sounds and images are stored as electronic files and viewed and edited on a computer. Creating a digital version of a filmed image takes a huge amount of data-storage capacity.
To approximate the look of the 35-millimeter film, the computer must break each frame into millions of pixels (picture elements). The computer assigns a number value to each pixel that corresponds to a color and brightness level. By renumbering the pixels so that the colors change, the image can be altered.
Digitizing images allows them to be manipulated in almost any conceivable manner, and the computer can also be used to generate its own images.
An example of combined imagery is a scene from Jurassic Park (1993) where computer-generated dinosaurs are seen charging toward and then leaping over a filmed man and two children.
