Tree shot
the long shot (often used as an establishing shot),
the full shot,
the medium shot,
the close-up.
Three less often used field sizes (see gallery below) are:
the extreme long shot (used for epic views and panoramas),
the American shot (also 3/4 shot), a slight variation of the medium shot to also include OWB handgun holsters in Western movies, a characterization from French film criticism for a type of shot in certain American films of the 1930s and 1940s also referred to as a "Cowboy shot" in reference to the gun holster being just above the bottom frame line,
the "Italian shot" or Extreme Close Up (ECU or XCU), where only a person's eyes are visible, named after the genre of Italo-Westerns, particularly the Dollars Trilogy by Sergio Leone, that established this particular field size.
