Photorealistic reproduction of the 1665 masterpiece by Dutch artist Johannes Vermeer, Girl with a Pearl Earring, under the form of a metasurface composed of millions of elliptical titanium-dioxide nanopillars of height 600 nm, and varying lateral dimensions and orientations. Scale bar: 50 μm. The “nanopainting” image is generated in transmission under polarized white-light illumination and imaged using a color-CCD camera through a polarizer placed after the metasurface.
