## Final prompt — portrait

Use case: photorealistic-natural. Asset: source photo for an open-source animated ASCII portrait demo, not ASCII art itself.
Create a visually arresting, photorealistic low-key studio head-and-shoulders portrait of an entirely fictional adult man around 30, short dark slightly tousled hair, sculptural cheekbones, calm serious expression, looking slightly past the camera, plain black shirt. No real person or reference image is to be used. Vertical 4:5, face very large in frame, full crown and chin visible with minimal margins.
The critical requirement is DRAMATIC DIRECTIONAL LIGHTING, not evenly exposed skin: a narrow warm-white key light from well to one side and slightly above creates a clearly illuminated forehead, ridge of nose, one cheekbone and the jaw, while the other half of the face falls into deep near-black shadow. A thin subtle cool rim on the dark-side hair and shoulder. A strong 8:1 or greater key-to-fill ratio, almost no frontal fill. Pure near-black seamless background; about two-thirds of the whole image should be very dark. The illuminated skin must be genuinely luminous, pale warm ivory in its brightest textured areas, with a rich bronze middle transition then charcoal shadows. Smooth modelling between the distinct bright and dark planes, not just an overall underexposed face. Real skin pores, fine stubble, crisp eye and lips. Highlights retain texture, no clipped white patches. Editorial fashion photograph with the drama of chiaroscuro, 85mm portrait lens. No beauty smoothing, gray flat lighting, heavy orange wash, props, lettering, logos, watermark, illustration or 3D face model.

## Final prompt — astronaut

Use case: photorealistic-natural. Asset: source photograph for an open-source animated ASCII art demo, not ASCII art itself.
Create an extremely striking close-up of a NASA Apollo/EMU-style astronaut helmet and upper spacesuit, facing three-quarter toward camera, floating against a completely black empty backdrop. Generic space-program equipment without NASA logos, agency insignia, flags, typography, or any implication of an official photograph. Vertical 4:5 composition, helmet dominates the frame, entire helmet dome visible, cropped upper chest, no scenery, no stars, no Earth. No recognizable face: dark gold reflective sun visor hides the wearer.
Dramatic hard side lighting with near-zero fill: one side of the off-white protective shell catches an intensely luminous but textured ivory light while the other side falls to near-black; a thin cold cyan rim picks out the shadow edge. The curved gold visor has a broad sculptural amber reflection that fades quickly into darkness; no featureless huge white reflection. Bright small mechanical catches, fabric weave, scratches, seals and tubing have believable photo-real texture and rich intermediate tones. Large connected shadow shapes occupy most of the picture, the upper shell and curved visor are described by sharp highlights and smooth graded reflection, not uniform exposure. A photographic space-equipment portrait, powerful, mysterious, exquisitely detailed, high contrast but no clipped white areas. No words, no logo, no watermark, no illustration, no flat frontal lighting.

## Final prompt — mecha

Use case: stylized-concept. Asset: source artwork for an open-source animated ASCII art demo, not ASCII characters itself.
Create an original Gundam-inspired Japanese heroic mecha HEAD AND SHOULDERS portrait, a spectacular realistic physical-model photograph / cinematic hard-surface render against a completely black backdrop. Not a reproduction of a named existing model: original proportions and panel architecture. Distinctive angular ivory armor plates, restrained vermilion chin accent, dark cobalt collar, two small luminous teal optics, an elegant split golden V-shaped crest; crest tips entirely inside the vertical 4:5 frame. Large head fills most of frame, slight three-quarter angle, cropped shoulder armor, no weapons or battle background.
VERY dramatic side lighting: a narrow warm-white key rakes over one side of the forehead, cheek armor and collar while the opposing side is submerged in deep near-black shadow, with a precise thin cyan edge light. At least half of the head is in rich shadow, and most of the whole image is dark. Bright ivory armor highlights remain textured, not blown out; highly readable light-versus-dark planes with metallic midtone gradients across curved pieces. Fine machined seams, restrained weathering, matte ceramic and anodized metal, sharp crisp silhouette. Sophisticated restrained cinematic color, not a uniformly lit toy, no busy colorful background. No text, manufacturer/series logos, typography, watermarks, grids, ASCII overlays or split panels.
