An upward-facing surface appears darker: the role played by the light-from-above assumption in lightness perception - Kobayashi Y, Morikawa K.

The human visual system can extract information on surface reflectance (lightness) from light intensity; this, however, confounds information on reflectance and illumination. We hypothesized that the visual system, to solve this lightness problem, utilizes...
