What do they see that I don't?

Alfred Hitchcock created many famous on-screen moments, where showing a zoomed-in reaction of shock and terror served to be more frightening to the viewer than fully revealing the entire scene. I've noticed that I've been favoriting a few artworks recently which provide similar room for an active imagination, to interpret close-up facial expressions, and what they may be reacting to.

Viewed as a group, something about the seemingly unfazed child 'Witnesses' and Nadeen, hypnotized by her phone (compared to the dramatic expression  shown in the 18th century old master), speaks to a now desensitized culture.
