depth of field

depth of field
  the depth of composition of a shot, i.e., where there are several planes (vertical spaces in a frame):
  1) a foreground
  2) a middle-ground, and
  3) a background; depth of field specifically refers to the area, range of distance, or field (between the closest and farthest planes) in which the elements captured in a camera image appear in sharp or acceptable focus; as a rule of thumb, the area 1/3 in front of and 2/3 behind the subject is the actual distance in focus; depth of field is directly connected, but not to be confused with focus
  Example: Extreme depth-of-field in many shots in Citizen Kane (1941) to heighten dramatic value, achieved by using very bright lighting and a slightly wide-angled lens by cinematographer Gregg Toland, causing objects or characters close in the frame's foreground to appear massive, while other objects appear smaller in the background; other scenes with extreme depth-of-field include the early snowball scene, the 'Crash of '29' scene, and Susan's overdose scene
