Videography refers to the process of capturing moving images on electronic media (e.g., videotape, direct to disk recording, or solid state storage) and even streaming media. The term includes methods of video production and post-production. It could be considered the video equivalent of cinematography (moving images recorded on film stock). The advent of digital video recording in the late 20th century blurred the distinction between videography and cinematography, as in both methods the intermittent mechanism became the same. Nowadays, any video work outside commercial motion picture production could be called videography. A videographer is a person who works in the field of videography and/or video production. News broadcasting relies heavily on live television where videographers engage in electronic news gathering (ENG) of local news stories.
Photography is the 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. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication
The arrival of computers and the Internet in the 1980s created a global environment where videography covered many more fields than just shooting video with a camera, including digital animation (such as Flash), gaming, web streaming, video blogging, still slideshows, remote sensing, spatial imaging, medical imaging, security camera imaging, and in general the production of most bitmap and vector based assets. As the field progresses, videographers may produce their assets entirely on a computer without ever involving an imaging device, using software-driven solutions. Moreover, the very concept of sociability and privacy are being reformed by the proliferation of cell-phone, surveillance video, or Action-cameras, which are spreading at an exceptional rate globally.
A videographer may be the actual camera operator or they may be the person in charge of the visual design of a production (the latter being the equivalent of a cinematographer).
