X-radiograph(s) of "Sarah Kilby (Cunningham)" 

Editor: This is an X-radiograph of John Greenwood's "Sarah Kilby (Cunningham)." It's fascinating to see the layers beneath the surface. What does the radiographic image reveal about its construction? Curator: The radiographic image discloses information not readily available through visual inspection. Notice the weave of the canvas. The density variations suggest areas of thicker paint application, perhaps indicating the artist's working method and compositional changes. Editor: Are there specific areas that stand out to you? Curator: Observe the face. The subtle gradations imply a delicate layering of pigments. It prompts us to consider the structural elements that contribute to the overall aesthetic effect. Editor: That's quite interesting; I hadn't considered the implications of paint density in that way. Curator: Indeed. Radiography provides a unique lens through which to analyze the formal qualities inherent in the work.
