From: The global structure of the visual light field and its relation to the physical light field Journal of Vision. 2016;16(10):9. doi:10.1167/16.10.9 Figure Legend: Subjective light source(s) position(s), where red dots represent single sources, and color dots represent pairs of sources. The actual positions of the light sources are shown using dotted lines. For (A) LAMP, all observers pointed at the lamp; for (B) DIFFUSE, the points were more spread out; and for (C) SPOTLIGHTS, most observers drew single sources, red dots and a transparent line for a single elongated source. The source next to the table lamp “is standing in front of the scene.” Four observers drew a pair of sources.
