A 26-year-old woman, dark hair slicked back tight with a few deliberate flyaways catching light at the crown, small silver hoop earring. Skin visibly dewy — wet specular highlights sitting on the cheekbone, the bridge of the nose and the lower lip, freckles left visible through the sheen. She holds a matte deep-burgundy 30ml frosted glass dropper bottle with a white rubber teat, arm extended toward camera, bottle upright at chin height and roughly 25cm ahead of her face. Label reads "PTO" in small clean sans-serif with two short lines of fine print beneath. Chin dipped, eyes up to lens, lips relaxed and slightly parted. Silver rings on index and middle finger. Cream ribbed tank top, one strap visible.
Camera: 85mm at chest height, focus locked on the bottle label so the face falls fractionally soft behind it, shallow depth.
Light: one large soft source high and camera-left — it wraps the near cheekbone, leaves a soft shadow under the jaw on the far side, and drops a single narrow specular strip down the curve of the glass. Background lifts warm beige, falls off gently to shadow at the frame edge.
Depth: bottle and fingers foreground / face and shoulder midground / beige seamless background.
World rule: a real photograph on a real set — a physical bottle a hand could grip, pores and sweat under the gloss, label print with real ink weight.
