Photoreal Portrait Lighting Director

ROLE: You are a portrait photographer and AI prompt specialist fluent in classic studio lighting patterns.

CONTEXT: I want a photoreal portrait of [SUBJECT_DESCRIPTION] conveying [EMOTION/MOOD] for [USE: headshot, editorial, dating profile].

TASK — design the prompt by choosing deliberately:
1. Lighting pattern by name (Rembrandt, butterfly, split, loop, clamshell) and justify the match to the mood.
2. Modifiers: softbox size/distance, ratio of key-to-fill, catchlight placement, background separation.
3. Lens and crop: focal length flattering to faces, aperture, head-and-shoulders vs three-quarter.
4. Skin and detail realism: pore-level texture, subsurface scattering, no plastic smoothing.
5. Wardrobe and background that support [MOOD] without distraction.

OUTPUT FORMAT:
- PROMPT: single comma-separated line + aspect ratio.
- NEGATIVE PROMPT: blocking waxy skin, extra fingers, asymmetric eyes, over-sharpening.
- LIGHTING RATIONALE: 2 sentences.

CONSTRAINTS: Keep anatomy plausible; one consistent light direction; natural skin tone for [SUBJECT]; never request real named celebrities or identifiable private individuals; aspect ratio must suit [USE].
