AUDIO / VIDEO |
|
Sound recording and reproduction is the electrical or mechanical re-creation and/or amplification of sound, often as music. This involves the use of Audio components such as microphones, recording devices and loudspeakers. From early beginnings with the invention of the Phonograph using purely mechanical techniques, the field has advanced with the invention of electrical recording, the mass production of the 78, the Magnetic wire recorder followed by the Tape recorder,the Microgroove recording, and the LP record. The invention of the Compact cassette in the 1960's, followed by the Walkman, gave a major boost to the mass distribution of music recordings, and the invention of Digital recording and the Compact disc in 1983 brought massive improvements in ruggedness and quality. The most recent developments have been in Digital audio players like the Apple iPod.
Video is the technology of capturing, recording, processing, transmitting, and reconstructing moving pictures, typically using celluloid film, electronic signals, or digital media, primarily for viewing on television or computer monitors.

Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras.
The word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally, the product of photography has been called a photograph. The term photo is a convenient abbreviation. Many people also call them pictures. In digital photography, the term image has begun to replace photograph. This term is neither more nor less correct than photograph, either in film or digital photography. (The term image is traditional in geometric optics.)
