Which risk affected image clarity when Byzantine mosaic tesserae lost definition?

💡 Explanation

Increased specular reflection reduced image clarity, because the tesserae surface became smoother at edges, causing direct reflections rather than diffuse scattering. Therefore, specular reflection increases rather than diffraction, because smoother facets change reflection angles.
