Trompe L’Oeil, the term from the French language, which literally translates to “fools the eye” can often be used to extend the space of a room or area. Again, full access to the space in the room is desirable so I can step back and really get the drawing right before I start painting. Trompe l’oeil requires extreme attention to detail. Proper perspective, nuance of light and gradation of color, is also considered in order to make the two-dimensional work appear three-dimensional.
This genre has been around since Antiquity, though the fun “Dark Ages” didn’t have much use for it. It wasn’t until the Italians (re)discovered linear perspective during the Renaissance that trompe l’oeil became popular for keeps. Don’t leave this up to a computer; let a classically trained artist have the fun and glory!
