Bill Viola is one of the better known contemporary new media artists. He is one of the few who managed to leave the specialist niche and achieve success (including commercial success). He is also one of the artists who helped to define video as a new and acceptable medium of artistic expression. The author does not present Viola's work in its entirety, bur rather focuses on 'The Reflecting Pool' project and the ontological questions related to video art and its relation to film, as a medium. According to him, Viola proposes that we treat the monitor as a new kind of canvas that allows the artist to create pictures ex nihilo, and yet at the same time he realises that a camera might also be directed at reality.
