Basic Prompt

Ultra high-definition black-and-white portrait of a mature man aged 60–80, captured in a tight head-and-shoulders composition. He has short white or silver hair, optional light beard stubble, and strikingly masculine features: deep-set eyes, a strong jawline, pronounced cheekbones, and textured skin showing natural pores, fine wrinkles, and age lines no retouching, no smoothing. His expression is calm, confident, and serene radiating quiet authority. Lighting uses dramatic chiaroscuro: sculptural, high-contrast illumination with deep shadows partially veiling one side of the face, while luminous highlights define bone structure. The background is simple, uncluttered, and fades into pure darkness, allowing the subject to emerge from shadow with elegant minimalism.

Known Limitations & Tips

Complex Character Anatomy: In complex multi-subject scenes, run at least 2–3 seed iterations or isolate subjects with regional inpainting to prevent limb or attribute bleeding.
Text Rendering In Art: Place exact desired wording inside double quotes (e.g. "Neon Sign"). Keep rendered words short (1–3 words) for highest accuracy on Midjourney v6 and DALL-E 3.
Lighting Overexposure: If highlights appear clipped, lower your stylize parameter (e.g. --s 150) or append diffused volumetric ambient lighting.
