Light: If the work is a two or three-dimensional object, is a source of light depicted or implied?
Is the light source natural or artificial? Do the shadows created by the light appear true to life, or has the artist distorted them?
In what way does he or she depict such shadows—through line, or color?
If the object shown is three-dimensional, how does it interact with the light in its setting?
How do gradations of shadows and highlights create form or depth, emphasis or order in the composition, architecture or sculpture?
How does reputation impact a hospital’s operations?
