There are several basic camera shots and techniques used in filmmaking. An establishing shot establishes the location and is usually wide. A long shot shows the entire subject and surroundings. A medium shot displays both characters and scenery to show actions or interactions. A close-up tightly frames a person or object, while an extreme close-up only shows a detail like eyes. Camera angles like high angles and low angles can influence how powerful or vulnerable a subject seems. Tracking follows a moving subject, while pans and tilts rotate the camera horizontally or vertically. Zooms change the focal length during a shot.
