Rayographs involve the interaction between objects and which type of surface/material?

• A. Light-sensitive materials
• B. Wooden substrate
• C. Copper plate
• D. Ink on canvas

Answer: (A)

Rayographs are camera-free images created by letting light reveal shapes on a surface that changes when exposed to light. The key is the interaction between objects and a light-sensitive surface, such as photographic paper or another coating that records light. When you place objects on this surface and expose it to light, the areas blocked by the objects stay different from the exposed areas, and after development the image of the shadows appears. This is why the surface/material is described as light-sensitive—the image depends on how light interacts with that material. Other materials like wood, copper plates, or ink on canvas belong to different processes (block printing, etching, or painting) and don’t describe the rayograph method.
