Differences between digital and traditional art are few. Digital art can be easily mass produced, while traditional art is more time-consuming. While traditional art can be digitized, the question remains, is the artist's internal rhythm missing in digital art? Can a computer interpret an artist's desire and emotional connection to the work?
Artistic taste relies on a culture. In past traditional art movements, art patrons were sometimes aghast by the "new" works being displayed. Art movements changed the technique of a familiar form, however, representing the idea of art in a different perspective.
Like traditional art styles, digital art is a new form that depends on technique and skills. Knowledge of traditional art theories are imperative to creating intelligent digital art.
Lighting, color theory, composition, perspective, values exist whether the art is digital or traditional.
All art is an illusion. A painter creates the image of a flower from lines and dots, colors and shapes. A paint brush or a fingertip become a tool for art creation. The computer, like a paint brush, is a tool. Digital art is merely another expression from within an artist's soul.
