Unlike folk art, naïve art does not necessarily derive from a distinct popular cultural context or tradition; indeed, at least in the advanced economies and since the Printing Revolution, awareness of the local fine art tradition has been inescapable, as it diffused through popular prints and other media. Naïve artists are aware of "fine art" conventions such as graphical perspective and compositional conventions, but are unable to fully use them, or choose not to. By contrast, outsider art ("art brut") denotes works from a similar context but which have only minimal contact with the mainstream art world.
