butterfly lighting
n.— «I usually place my beauty dish as close to the model as I can. Why? Because the closer the light is to your subject, the softer the light. My dish is placed high above the face, angled down on it at about a 45 degree angle. It also can be placed directly centered above the model’s face. This is normally referred to as “paramount” lighting. It got its name from Paramount Studios. This lighting was used constantly as a female “glamour” light. Remember the old Hollywood portraits made famous by photographers like George Hurrell? He used this lighting to accent the cheekbones and give a broad look to a narrow face. It is also sometimes referred to as “butterfly lighting” because of the small butterfly shadow under the nose.» —“Beauty Lighting” Fashion Photography Blog Sept. 28, 2008.
