Camera shot with a partially framed actor in the foreground (10–25% of frame) while the principal actor remains in sharp focus.
Technical Details
In a Dirty Single, the camera is positioned approximately 15-30 degrees away from the direct line of sight to the main subject. The cut-off conversation partner occupies 10-25% of the frame, usually in the first third. Lenses between 35mm and 85mm (full-frame equivalent) are optimal, as they create natural proportions without extreme depth-of-field effects. The depth of field is chosen so that the cut-off person appears slightly out of focus, while the main subject remains sharp.
History & Development
The Dirty Single developed in the 1940s as an evolution of the classic shot-reverse-shot editing. Directors like Orson Welles and William Wyler first systematically experimented with this shot to clarify spatial relationships between characters without hard cuts. By the 1970s, the technique had become a standard tool of New Hollywood cinema. Modern digital cameras with high-resolution sensors now allow for more precise control over focus fall-off and image composition.
Practical Application in Film
A classic application of the Dirty Single can be found in dialogue scenes of "The Godfather" (1972), where Gordon Willis used it to visualize power dynamics between characters. In "Her" (2013), Spike Jonze employs the shot to emphasize the protagonist's emotional distance from others. The technique reduces the editing rate in dialogue scenes by 30-40% compared to classic shot-reverse-shot editing, thereby significantly speeding up the shooting process.
Comparison & Alternatives
In contrast to a pure single shot (Clean Single), the Dirty Single maintains spatial context without needing to cut to a wide or medium shot. The Over-the-Shoulder shot shows more of the conversation partner, while the Dirty Single places a stronger focus on the main subject. Modern alternatives include the "Floating Single," where the cut-off person drifts into frame through camera movement, and the "Echo Single" with reflected image elements in mirrors or windows.
