Photography Video and Digital Imaging

Digital usually refers to something using digits, particularly binary digits.

Imaging is the representation or reproduction of an object's form; especially a visual representation (i.e., the formation of an image).

Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.
