Depth of Field
Depth of Field
 The distance range between the nearest
and farthest objects that appear in
acceptably sharp focus.
 Depth of field depends on the lens
opening, the focal length of the lens,
and the distance from the lens to the
subject.

Type of Close-ups
 Cut-in close-up: a magnified portion of the
preceding large scene. The audience’s
curiosity should be satisfied by bringing
them closer, otherwise the viewer may lose
interest.
 Cut-away close-up: is related to, but not a
part of, the previous scene. Cut-away closeups may be filmed from three camera
angles: Objectively, Subjectively and pointof view.
The Power of Close-ups
 A properly chosen, expertly-filmed,
effectively-edited close-up can cause
dramatic impact and visual clarity to the
event.
 Close-up should be considered from both
visual and editorial standpoints.
 Important in theatrical production: camera
angle, image size and lighting of theatrical
close-ups.
