The technique used to fool the eye by creating convincing 3D illusions is known as what?

• A. Trompe l'oeil technique
• B. Chiaroscuro
• C. Sfumato
• D. Impressionism

Answer: (A)

Fooling the eye with a painting that reads as three-dimensional relies on high realism and precise depth cues, so viewers perceive actual space on a flat surface. The best term for this technique is trompe l’œil, which literally means “fool the eye.” Artists using trompe l’œil study perspective, proportion, light, shadow, and edge precision to make painted objects appear as if they exist in real space, sometimes even resembling real openings, textures, or objects.

Chiaroscuro focuses on strong light-and-dark contrasts to model form and volume, not on creating an overall optical illusion of depth. Sfumato blends tones softly to remove hard edges and create atmosphere, rather than tricking the eye into perceiving a different reality. Impressionism emphasizes capturing fleeting light and movement with visible brushwork, not convincing three-dimensional illusion.
