An example of this is understanding how the simple combination of shots can create an additional idea: the blank expression on a person's face, a piece of an appetising cherry-topped chocolate fudge cake, and then back to the person's face. While nothing in this sequence literally expresses hunger—or desire—the juxtaposition of the images convey that meaning to the audience.
Unraveling this additional meaning can become quite complex. Lighting, angle, shot duration, juxtaposition, cultural context, and a wide array of other elements can actively reinforce or undermine a sequence's meaning.
