It’s a rainy late fall day in New York City and the Metropolitan Museum of Art is crowded. Even Walter Liedtke, one of the museum’s curators, has to vie for viewing space. As he tells the story of a once debated Rembrandt painting, he has to shuffle to the side to make room for some patrons.
"I can’t really see it on the surface, but in X-rays there’s been a lot of discussion as to whether this picture was longer on the bottom," he described, before being interrupted.
Studying the weaves of the canvas is done by shooting x-rays through the layers of paint and exposing what’s behind the image most only glance at on the wall.
