Beginning to work with digital technology as an artist raises particular challenges that need to be considered. Many artists begin to use digital technologies because there are not so many conventions constraining accepted sorts of practice. Although it is 50 years since artists first used computers for making art, it is still somewhat unformed as a practice. It is still fluid and supple and artists feel that they can test out what can be done. It is also crucial that the inherent quality of the media is understood.
