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.
The General Principles that Govern Depth of Field Greater depth of field Less depth of field Wide-angle lenses Telephoto lenses High f-stop(small aperture) Low f-stop (wide aperture) Subject far away from camera Subject close to camera

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.
