Jurassic Park is just such an incredible well-lit film, oh my god.
When the crew sees the baby raptor being born, Spielberg takes us from this really warm moment under the heat lamp:
To Ian Malcolm leaning on a desk, with a bright white lamp as a spotlight insisting that we really pay attention - in this spotlit set-up he delivers the most important line of the film, "Life finds a way."
To Dr. Grant, frightened, hit with an alarming noirish backlight as he realizes he's holding a velociraptor.
Three really evocative lighting schemes within the same scene, totally diagetic and effortlessly communicative.
