Using infrared reflectography, conservators at the Getty Museum have produced an infrared reflectogram of what lies beneath Jan Van Eyck's Ghent Altarpiece. In the site's current phase, you can see hi-res images of the altarpiece both opened and closed, and can compare two images at once. The Met offers further information about the altarpiece, while the National Gallery explains a smaller-scale project devoted to Jan van Eyck's portrait of his wife.
