Butterfly Lit Beauty Portrait

A beauty portrait lit with butterfly lighting: one large source directly above and in front of the face, a reflector held just below the chin, casting a small symmetrical shadow under the nose. The subject is a [age range] person with [skin tone] skin, shoulders square to a 100mm lens at f/5.6, pale [backdrop colour] background. Clean even light, glowing skin with pores and fine hairs still visible, catchlights at the top of both eyes. Minimal styling, simple neckline, hair pulled back. Photorealistic, aspect ratio 4:5. No smoothing that removes texture, no text, no watermark.
