(Northwestern University) A partnership of the Northwestern University/Art Institute of Chicago Center for Scientific Studies in the Arts, the Art Gallery of Ontario and the National Gallery of Art has used multiple modes of light to uncover details hidden beneath the visible surface of Pablo Picasso's painting 'La Miséreuse accroupie', a major work from the artist's Blue Period. The researchers found images connected to other works by Picasso as well as a landscape — likely by another Barcelona painter — underneath Picasso's painting.
