Since 1980, I have been working and producing original artwork principally at the level of the *digital* image; as opposed to the physical, tangible object. Thus my visual artistic output is only viewable either on-screen; or after being physically transferred to film, canvas or paper.
In these conditions, the concept of an 'original' piece of artwork in the conventional understanding of the term is somewhat nonsensical - a concept sometimes difficult to grasp for those unaccustomed to the non-physical nature of the digital world.
Nevertheless, the physical end-product of the great majority of my work is almost always a sole one-off hard-copy image on either canvas or paper; individually produced and signed in a single physical edition to render the work easily accessible/physically transportable.
These pieces are in all respects unique. I therefore refer to them as : digital originals.
