X-radiograph(s) of "Artist and Wife" 

Editor: Here we have an X-radiograph of "Artist and Wife," originally by Gabriel Metsu. It's quite abstract! What can we learn about the painting through this technical view? Curator: Notice the internal structure revealed. The wood grain's directionality creates a subtle linear pattern. These disruptions—the dark spots—likely represent areas of pigment or filler. Editor: So, the X-ray visualizes the physical composition. Curator: Precisely. We can see evidence of the artist's process, the materiality of the support, and how the composition has been built up. The frame too has a strong presence in the image, doesn't it? Editor: Yes, the level of detail is amazing. I now have a new understanding of how art is constructed, layer by layer.
