 Because of the way the human eye processes visual information, it is less suited to pick up shadows directly; however, peripheral vision can pick up shadows well.Research in 2008 by a geomorphology professor at Urbino University and an artist-photographer revealed likenesses of "Mona Lisa"s landscapes to some views in the Montefeltro region in the Italian provinces of Pesaro and Urbino, and Rimini.The "Mona Lisa" has survived for more than 500 years, and an international commission convened in 1952 noted that "the picture is in a remarkable state of preservation."
