The word “diaporama” has been first used in 1958 by Claude Madier, while he was in charge of the Photo-Club in Vichy. The usual definition mentions “a flow of pictures screened with the crossfade technique on a single screen along with a sound track”, provided the consistancy of the entire show is characterized by the intellectual input of the author.
Nevertheless, far from these high level questions, the Digital AV is today recognised as a full mean of expression, quite easy to set up and work with, along with almost unlimited possibilities.
Technical progress, digital sound and photography, make the Digital AV a perfect audiovisual tool to inform, to give evidence, to let people dream... Moreover, with the introduction of new generations of softwares, it’s already possible to create and transmit Digital AV’s at the finger tip.
