A novel describes a crowded street in several sentences. Its adaptation gives us footsteps, a vendor’s call and a passing vehicle before we have time to inspect the whole image. Comparing the two works can begin with the kind of attention each asks from us.
Choose a short location passage and the corresponding screen moment. First list the details actually supplied by the prose. Separate a physical description from a judgment made by the narrator. Then listen to the filmed scene without trying to find a sound for every noun in the book.
Suppose, in an imagined adaptation, a passage calls a street restless. The film might place an interrupted conversation against traffic that repeatedly swells and falls. This is one possible way to organise restlessness, not proof that the filmmaker intended a direct translation of that adjective.
Write down when the sounds become noticeable. Are they present immediately, or do you register them only when speech stops? Does the scene move away while a sound continues? These observations are more useful than rating the soundtrack as simply realistic.
Finish with two sentences: what the prose lets you dwell on, and what the sound makes you experience in time. The comparison may reveal a change of emphasis rather than a missing detail.
There is no obligation for every descriptive sentence to survive as a visible or audible item. A strong discussion explains how the adaptation builds a place, including the parts it chooses to leave to the viewer.
