Rock star treatment for a Renaissance mural

An elaborately painted 16th century chapel damaged during the Second World War is being restored not with paint but with light.

The German building, now a museum, was originally painted by Hans Ritter, a student of Lucas Cranach the Elder. The building was damaged in World War II, but a 19th century watercolor of the interior shows the wall paintings intact.

Instead of a traditional restoration, conservators have turned to a company that creates light shows for rock concerts. The technology used in light shows allows images to be accurately projected onto curved surfaces. Now, a projection of the 19th century watercolor fills in the space where the original decoration was. The new method is non-invasive and completely reversible. [photo]
