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 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.

Hyperfocal Distance  The hyperfocal distance is the point of focus where everything from half that distance to infinity falls within the depth of field.

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.  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.

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 close- ups may be filmed from three camera angles: Objectively, Subjectively and point- of view.  Cut-in close-up: a magnified portion of the preceding large scene.
