What is the primary functional difference between the Gaffer and the Grip team on a set?

Answer

The Gaffer shapes the light hitting the subject, while the Grip shapes the environment around the light and camera.

The text explicitly notes the functional divide: the Gaffer interprets the lighting plan to shape the light on the subject, whereas the Grip team manages the setup of supports, dollies, and rigging equipment in the surrounding environment.
