Yesterday I was able to attend a presentation at OMSI (
Oregon Museum of Science and Industry) by
Pascal Cotte. OMSI is opening an exhibit on Leonardo da Vinci, featuring a whole room devoted to Cotte's 240-megapixel, multi-spectral scans of the Mona Lisa. Cotte not only invented the camera which uses 13 wavelengths from ultraviolet light to infrared; he also supervised the exhaustive analysis of the resulting images.
Through this analysis Cotte is able to reveal hidden details of how da Vinci painted the Mona Lisa, and how she appeared to da Vinci's contemporaries. The exhibit highlights Cotte's discovery of
25 secrets about the Mona Lisa, including evidence that she did in fact have eyebrows.
