Paintings today can come in two forms: digital or "real" meaning oil on canvas for example. I have been a "real" painter for over 30 years but I recently switched to digital for a few reasons: 1) it is green art, meaning there are no toxic chemical; 2) It is not stinky 3) I don;t need to spend month of drying time on a single painting and 4) Digital textures look better on printed art than a photo of a "real" art since the textures are digital themselves and stay looking like textures on the printed canvas.
