Art Surfaces are simply Photoshop templates that apply lighting and shading to your artwork as you draw or paint to make it appear that you painted or drew on the paper, canvas or board itself. Ink appears to soak in, light catches the raised areas while the texture below shows itself. They are in development and will be available for purchase when they’re ready. (I can tell you when)
How do I use them in Photoshop?
Just draw, paint or paste your artwork onto the green layer and the template does the rest.
