1. What is the primary analytical outcome?Exaggeration of surface topography and relief through enhanced shadow casting
2. What is the key application domains?Art conservation, historical artifact examination, forensic analysis, materials science
3. Why do we use raking light instead of normal light?Normal light makes surfaces look flat, while raking light exaggerates shadows from small details, making cracks, scratches, and brush strokes easier to see.
4. How do people set up raking light for a picture?They put the light source close to the object and angle it less than 10 degrees from the ground, and sometimes adjust the light’s brightness and color to make the details pop.

Grazing Incidence Illumination: Synonym for raking light, emphasizing the low angle of light incidence on a surface.
Surface Topography: The detailed physical features of a surface, including its texture, relief, and micro-structure.
Material Integrity: The state of being whole and undamaged; the structural soundness of a material.
