Pascal Cotte announced at a press conference Wednesday that he has found definitive proof that when Leonardo da Vinci painted the original portrait he included “Mona Lisa’s” lashes and brows.
Pascale Cotte engineer and founder of Lumiere Technology, largely contributed to the knowledge of the Mona Lisa thanks to the multispectral digitization of the famous painting. The hidden knowledge of the true colors was revealed by multispectrally scanning the painting in thirteen channels – from Ultra Violet to Infra Red. Then the spectral response curve of the varnish in each pixel was isolated and subtracted from the digital file to virtually reveal the surface of the painting when it had freshly exited Leonardo da Vinci’s workshop.
Cotte examined the world’s most famous painting using a high-definition camera of his own design. The device scanned a 240-million pixel image using 13 light spectrums, including ultra-violet and infrared. The resulting ultra-high resolution photograph of 150,000 dots per inch yielded a reproduction of the “Mona Lisa’s” face magnified 24 times. And there Cotte found the evidence he sought : A single brushstroke of a single hair above the left brow.
