Introduction to Lighting

Monocular Cues
Relative Size
When we see two objects that we assume to be of similar size (such as two people) the one that appears larger is interpreted to be closer.
 
Interposition
If one object blocks our view of another, we assume that it is in front. René Magritte, The Blank Signature, 1965, National Gallery of Art, Washington DC
