Candid Black and White Bedroom Portrait Prompt

Close-up portrait, 85mm f/1.4, a {argument name="subject description" default="young East Asian woman in her early 20s"} sits at the edge of her bed in a dim bedroom, hunched slightly forward, elbows on knees, face tilted down in thought, authentic daily life photography, natural candid moment. Almond-shaped eyes with downcast gaze aimed at the floor, expression contained and held — not crying, not calm, somewhere in the held-breath space between. Strong jaw slightly tensed. Straight black hair falls forward around her face, curtaining partially. Skin with natural texture, visible fine lines around eyes from tiredness, subsurface scattering under low side lamp light. She wears an {argument name="clothing" default="oversized men's cotton shirt"}, buttons partially done, hem long over thighs. Phone held loosely in one hand beside her knee, not being looked at. Several stray hairs fall forward with gravity, not arranged. Black and white rendering. Low key: single bedside lamp as only light source, positioned low and to one side, casting half her face in deep shadow with soft falloff — shadow side retains detail and tonal gradation, not crushed to black. Mid-tones preserved in shirt fabric and bedding texture. Grain structure visible and tactile, ISO 800 film grain, photographic texture not CG render smoothness. Aspect ratio 4:5. No watermark, no text overlay, not cartoon, not digitally painted, not illustration, not anime.
