The dark side of gloss Juno Kim, Phillip J. Marlow, Barton L. Anderson
Supplementary Figure 1. Complex illumination environments generate salient specular patterns. A surface with relief rendered in the St Peter's Basilica illumination field generates both bright reflections of the primary light source (specular highlights), and environmental reflections that can be either bright (midlights) or dark (lowlights). Note that a percept of gloss is experienced in the absence of a clear image of the surrounding surfaces in the body of the object.

Supplementary Figure 2. Specular lowlights generate the appearance of gloss in natural surfaces. A glossy red cup photographed with a vertically oriented specular lowlight produced by a dark chord in the foreground (left) appears glossier than the same cup without the lowlight (right). Both cups generate similar specular highlights at the far side of their inner walls, but the left cup with the isolated lowlight generates the most compelling appearance of gloss.
