Single close-up of a person without obstructing foreground elements, typically 50–135mm focal length, face positioned in rule of thirds.
Technical Details
The focal length typically ranges from 50mm to 135mm (35mm equivalent) to ensure natural facial proportions. The framing follows the Rule of Thirds: the face is positioned in the right or left third of the frame, with the gaze directed into the empty third. Standard framings include Medium Close-Up (chest up), Close-Up (shoulders up), and Big Close-Up (face only). The depth of field at f/2.8 to f/4.0 is approximately 30-60cm to keep the background intentionally blurred. Modern productions often use 85mm lenses for flattering compression.
History & Development
Orson Welles and Gregg Toland perfected the Clean Single in 1941 in "Citizen Kane" through deep focus experiments with 25mm wide-angle lenses. The classic Hollywood era (1930-1960) standardized the shot-reverse-shot rhythm with alternating Clean Singles. Vilmos Zsigmond revolutionized the aesthetic in 1974 with "The Conversation" using 200mm telephoto lenses, which created extreme image compression. Digital cameras from 2005 onwards enabled extended depth of field control in Clean Singles due to larger sensors (Super35, Full Frame).
Practical Use in Film
Christopher Nolan uses Clean Singles with 65mm IMAX cameras in "The Dark Knight" (2008) for Joker interrogation scenes to enhance psychological intensity. The workflow follows the A/B camera system: Camera A shoots Clean Single Person 1, Camera B Clean Single Person 2, both simultaneously with identical focal lengths. "Her" (2013) exclusively uses Clean Singles on Joaquin Phoenix to visualize emotional isolation. The editing pace averages 3-8 seconds per Clean Single in dialogue scenes.
Comparison & Alternatives
Over-the-Shoulder Shots show spatial relationships, while Clean Singles eliminate context in favor of emotional focus. Two-Shots maintain group dynamics, whereas Clean Singles isolate individual reactions. Dirty Singles with cropped foreground elements create spatial continuity – Clean Singles deliberately break this. Modern split-screen techniques replace classic Clean Single montages with simultaneous depiction. Steadicam moves between Clean Singles create fluid transitions without hard cuts.
