Butterfly lighting is a three-point lighting setup where the key light is positioned above and centered on the subject.
Technical Details
The light source is placed at an angle of 15-30° above the subject's horizontal eye line, with 22° considered the standard. Typically, 2K-5K Fresnel spotlights or modern LED panels from 200W with CRI values above 95 are used. The nose shadow should extend no further than the upper lip and should be symmetrical to the center of the face. Modifications are made using 60-80cm softboxes or 42-56cm diameter beauty dishes. A fill light is used frontally with a 1:3 to 1:2 light ratio.
History & Development
George Hurrell perfected the technique in 1929 at MGM for star portraits, establishing the visual standard for Hollywood portraits of the 1930s-40s. Cinematographer Gregg Toland adapted Butterfly Lighting in 1941 for "Citizen Kane" in the Susan Alexander scenes. In the 1950s, ASC member George Folsey developed the "Paramount variation" with additional hair lights. Digital LED technology, starting in 2010, enabled more precise color temperature control at 3200K-5600K with ±100K tolerance.
Practical Use in Film
"Casablanca" (1942) utilized Butterfly Lighting for Ingrid Bergman's close-ups, while "Vertigo" (1958) employed the technique for Kim Novak's transformation. Modern applications can be found in "La La Land" (2016) for Emma Stone's audition scenes and "Blade Runner 2049" (2017) for Joi hologram sequences. Setup requires 15-20 minutes for basic configuration, with fine adjustments taking an additional 10-15 minutes. Disadvantages arise with wider faces due to increased shadow formation and with deep-set eyes due to the "raccoon eyes" effect.
Comparison & Alternatives
Rembrandt lighting creates triangular highlights instead of butterfly-shaped shadows and positions the light source laterally rather than frontally. Split lighting divides the face in half, while Butterfly Lighting ensures symmetrical illumination. Loop lighting uses shallower angles of 5-15° and produces rounded nose shadows. Modern clamshell lighting combines a butterfly setup with a floor reflector for softer shadows in beauty shots.
