Close-up portrait photograph of a 34-year-old woman with long, straight brown hair, sitting by a window at home. An ordinary face: a few freckles, faint lines at the eyes, visible pores, no makeup. Shot on a full-frame camera with an 85 mm lens at f/2.8, from about 1.2 m, at eye level. Soft daylight comes from a window to her left, out of frame, at about 5500 K: it lights the near side of her face and falls off into shadow on the far side. The look of 35 mm colour negative film: fine grain, natural colour, low saturation. Unretouched skin.

close up portrait of a beautiful woman with long brown hair, realistic, 4k

close up portrait of a beautiful woman with long brown hair, realistic, 4k. Skin: real down to the pores, fine peach fuzz on the cheeks and jaw, a mole or two placed off-center, faint redness where small vessels show, each pore's tiny shadow falling the same way as the scene's light. Light: from the scene's own sources, off-frame to one side, catching the brow, nose and cheekbone, then falling off into shadow; nothing lights the face flat from the front, nothing fills the shadows back in. Finish: skin never glows or shines in hot patches, no retouching or beauty grading, no smoothing, no waxy or CG-perfect skin, no oversharpened edges, a fine even grain.

professional product photography of a perfume bottle, black background, hyperrealistic, 4k

Tabletop product photograph of one clear glass perfume bottle with no label, about 11 cm tall, rectangular with thick walls, a pale amber liquid filled to two thirds and a matte black cap. It stands alone on a black surface against a black background. Shot on a medium-format camera with a 120 mm macro lens at f/11, straight on at the bottle's mid-height, the whole bottle sharp. The light comes from behind the bottle on both sides, out of frame, so the glass edges glow as thin bright lines against the black; no light from the front. Neutral colour, deep blacks, no colour cast. No text, no logo.
