Like loop lighting, butterfly lighting is named after the specific type of shadow that is created on your model’s face. Position your light in front and above your subject to create a butterfly-shaped shadow under their nose. This lighting is often seen in glamour shots and headshots. It will also serve to highlight the other facial features with the same level of severity, which can be great for accentuating high cheekbones, but may not be useful if your model has deep-set eyes as it can result in too much shadow under the eyes.
