There are people out there in the world who look down on digital art as though it's somehow "cheating" and not real art. When I tell them I create my paintings on a computer, they do their best to hide their disdain. But I can tell.
I have friends who are artists, and I know they think my art is not legitimate. How do I know? Because they never ask me about it. If they thought it was "real" art, they'd be interested. But they don't ask. Ever. I'm not exactly sure why, but I suspect to their minds, if they were to show interest it would somehow legitimize a form of art they feel lacks authenticity.
To be clear, I don't think digital art should command the same dollar value as traditional art. Obviously, something that can so easily be reproduced is not as valuable as a one of a kind, done-by-hand painting. But that's not what I'm talking about.
Art is not about a dollar value, it's about the act of creation. My digital paintings are as legitimately "art" as a Rembrandt self portrait. I am NOT saying they are as valuable. I am NOT saying they are historically significant. What I AM saying is that both are legitimate artistic human expressions.
Human expression. That's what art consists of - whether created with a finger, a brush, or an electronic stylus.
