One thing that a lot of people can't get their head around with digital art is that there is no such thing as what might be thought of as an original. They seemed to be conditioned to think that visual art has to be a solid thing that you can touch. They also tend to think that if you have that digital art printed out then it's somehow not proper, just a copy. Which in reality it is. Just a copy.
It freaks people out that with something digital you can only print it out and that there is no limit on how often this happens. Art can be mass-produced. Fantastic! Obviously those that have a vested interest in perpetuating the notion that art is an investment commodity wouldn't care for. But bollocks to them.
When I first started advertising/exhibiting my digital art I had the idea that I should only offer it as limited edition fine art prints. I now realise I was probably wrong to do so. It goes a bit against the grain of what I believe. So I've decided to honour the limited edition pictures that I'm already committed to but going forward I intend to put no limit on the number of prints of anything new that I produce. I also plan to offer pictures as cheaply as I can. Watch this space.
