Look at this painting by Francisco Zurbaran. Which technique is demonstrated?

This painting by Francisco Zurbarán titled "Still Life with Lemons, Oranges and a Rose", showcases the technique of Trompe-l'œil. This technique involves creating an illusion of three-dimensional objects on a two-dimensional surface. In this case, Zurbarán's highly detailed, lifelike depiction of the fruits, rose, and the reflective metal dish, aims to deceive the viewer's eye, creating the impression of real, tangible objects.
