Mona Lisa's Eyebrows
The Mona Lisa is one of many iconic images in our culture. Much has been written about her enigmatic smile. Many have parodied the image (think Lisa Simpson).
A French engineer designed a special camera and created a 240 million pixel image of the painting.
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.
