Audio & Visual Media

Digital media (as opposed to analog media) are usually electronic media that work on digital codes. Today, computing is primarily based on the binary numeral system. In this case digital refers to the discrete states of "0" and "1" for representing arbitrary data. Computers are machines that (usually) interpret binary digital data as information and thus represent the predominating class of digital information processing machines. Digital media ("Formats for presenting information" according to Wiktionary:media) like digital audio, digital video and other digital content can be created, referred to and distributed via digital information processing machines. Digital media represents a profound change from previous (analog) media.

Digital data is independent of its interpretation (hence representation). An arbitrary sequence of digital code like "0100 0001" might be interpreted as the decimal number 65, the hexadecimal number 41 or the glyph "A". See also: ASCII, Code.

Florida's digital media industry association, Digital Media Alliance Florida, defines digital media as "the creative convergence of digital arts, science, technology and business for human expression, communication, social interaction and education".

There is a rich history of non-binary digital media and computers.

[edit] Data conversion

Main article: Analog-to-digital converter

The transformation of an Analog signal to Digital information via an Analog-to-digital converter is called sampling. According to information theory, sampling is a reduction of information. Most digital media are based on translating analog data into digital data and vice-versa (see digital recording, digital video, television versus digital television).

As opposed to analog data, digital data is in many cases easier to manipulate and the end result can be reproduced indefinitely without any loss of quality. Mathematical operations can be applied to arbitrary digital information regardless of its interpretation (you can add "2" to the data "65" and interpret the result either as the hexadecimal number "43" or the letter "C"). Therefore, it is possible to use the same compression operation onto a text file or an image file or a sound file. The foundations of operation on digital information are described in digital signal processing.

The following list of digital media is based on a rather technical view of the term media. Other views might lead to different lists.

Digital art is any art in which computers played a role in production or display of the artwork. Such art can be an image, sound, animation, video, CD-ROM, DVD-ROM, videogame, web site, algorithm, performance or gallery installation. Many traditional disciplines are now integrating digital technologies and, as a result, the lines between traditional works of art and new media works created using computers has been blurred. For instance, an artist may combine traditional painting with algorithm art and other digital techniques. Often, the medium itself is considered the artwork. As a result, defining computer art by its end product can thus be difficult. Nevertheless, this type of art is beginning to appear in art museum exhibits.

Comic book artists in the past would generally sketch a drawing in pencil before going over the drawing again with India ink, using pens and brushes. Magazine illustrators often worked with India ink, acrylics or oils. Currently, an increasing number of artists are now creating digital artwork.

Digital artists do, simply, what centuries of artists have always done by exploring and adopting a culture's new technology toward the making of a personal imagery. In doing so the culture is also reflected in the artwork as is the artist's personal vision. As our culture becomes increasingly digitized, digital artists are leading the way in exploring and defining this new culture. Digital Artists use a medium that is nearly immaterial, that being binary information which describes the color and brightness of each individual pixel on a computer screen. Taken as a whole an image consisting of pure light is the feedback devise that tells an artist what is being made and simultaneously stored on the computer's hard drive. Digital Artists employ many types of user interfaces that correspond to the wide variety of brushes, lenses or other tools that traditional artist use to shape their materials. Rather than manipulating digital code directly as math, these electronic brushes and tools allow an artist to translate hand motions, cutting and pasting, and what were formerly chemical dark room techniques into the mathematical changes that effect the arrangement of screen pixels and create a picture.

Digital Art is created and stored in a non-material form on the computer's memory systems and must be made physical, usually in the form of prints on paper or some other form of printmaking substrate. In addition, digital art may be exchanged and appreciated directly on a computer screen in gallery situations or simultaneously in every place on the globe with access to the web. Being immaterial has its advantages and with the advent of high quality digital printing techniques a very traditional long lasting print of this artwork can also be produced and marketed.
