X-radiograph(s) of "Swamp" 

Editor: Here we have an x-radiograph of "Swamp" by George Inness. It's so interesting to see the layers beneath the surface. What can you tell me about the structure revealed here? Curator: Notice the underlying composition, the artist's initial blocking of forms. The density variations suggest areas of thicker paint application, revealing the artist’s process of layering and revision. How does this radiographic view alter your perception of the final image? Editor: It shows the painting wasn't created in one go, doesn't it? That the artist built up the image over time. Curator: Precisely. It exposes the evolution of form and the artist's manipulation of materiality to achieve the final visual effect. Editor: I see how a different lens can give us a whole new appreciation for the artwork!
