Italian website Haltadefinizione has posted a number of ultra high resolution photos of works by classic painters, including Leonardo da Vinci and Michelangelo Caravaggio. Their most recent image, Botticelli’s La Primivera, is made of 28 billion pixels (as a reference, that’s 3,000 times the resolution of a consumer digital camera). To take advantage of this insanely high quality, users can zoom in to all the way to cracks and shadows of the canvas. Go and check it out here. [via Boing Boing]
